Problems ml 166 with mileage. Mercedes-Benz introduced the new ML-Class W166

Mercedes W166 differs from most in compact dimensions, a high level of safety and a wealth of equipment. German designers have developed universal car according to the canons of the US market - with a voluminous trunk, fast on the highway and providing high permeability off the roads. In front of the body, the W166 resembles the more expensive Mercedes-Benz GL-Class - almond-shaped headlights are located high on the ledges of the front fenders, the radiator grill has similar three horizontal bars and the Mercedes logo. The W166 has the same huge bumper, equipped with multi-level air intakes, bright inserts and stylish strips of LED daytime running lights. The hood is raised above the front, which gives the appearance of the car a solid haughty look.

The history of the Mercedes Benz ML W166

It was shown in 1997. These cars were intended primarily for the North American market. AT Western Europe they appeared in the spring of 1998. Three versions of the model were proposed with . The vehicles are equipped with hydromechanical automatic transmissions with a speed limiter system. Also included in the package was an independent suspension of all wheels, a transfer case with a reduction gear, a frame chassis.

Mercedes Benz ML-Class (W166) was officially presented in autumn 2011 at the Frankfurt Motor Show. It appeared in Russia in the spring of 2012. When changing generations, the SUV retained the platform of the previous W164 model, but increased in size.

Technical features of the Mercedes Benz ML-Class W166

Initially, the car was designed in such a way as to ensure the greatest possible safety in a collision. The Mercedes M-Class provides passengers with above-average protection potential. The SUV is made on the basis of a frame structure. Three crossbeams and two rigid box profiles are welded into a ladder-like structure.

The body is securely connected to the frame with ten rubber mounts, which minimize vibrations and noise while driving. Thanks to such a strong design, in any collision, Mercedes passengers are practically not endangered due to the fact that the body is deformed, while the cabin volume remains constant and leaves enough space for survival.

This model implements original technical ideas, first of all, it is an all-wheel drive, constantly on. The specialists did not use differential locks in the junction box and drive axles, but at the same time they provided an electronic traction control system on each wheel. All models except the ML 230 are equipped with Dynamic Stability Control, which improves vehicle stability on all roads.

Mercedes Benz ML-Class (W166) is equipped as standard with an active ASSYST service system, electric windows and mirrors, airbags, anti-theft system, power steering, light-alloy rims, central locking with remote control, air conditioning.

The body colors are quite diverse: standard black, white tones, obsidian black, tenorite gray, iridium silver, tanzanite blue, citrine brown, pearl beige, palladium silver. The salon is spacious and bright, has many functions. But the basic features for comfortable driving are provided in additional options.

Interesting facts about the Mercedes Benz ML-Class W166

The Mercedes logo was designed in 1909. According to the official version, it symbolizes the company's success on land, in water and in the air, as the company was engaged in the production of not only cars, but also engines for aircraft and ships. There is also an option according to which three beams mean the trinity of the driver, passenger and mechanic, which guarantees safety for the driver, convenience for the passenger, reliability for the mechanic.

A test drive of the Mercedes Benz ML-Class (W166) in Russia took place on July 21 at Panavto. Two versions were presented on the test: Mercedes ML350 gasoline and ML350 with sports equipment. Participants agreed that diesel showed itself better than gasoline. Good acceleration, pleasant sound, silence in the cabin. Mercedes ML has become more luxurious, more ergonomic, but at the same time has not lost touch with previous generations.

Pros and cons of Mercedes Benz ML-Class W166

Mercedes Benz ML-Class (W166) has several advantages: a pleasant and spacious interior, reliable engine, optimal flow fuel, a large user-friendly display and a roomy trunk.

Among the minuses, one can note not the most convenient flat mirrors, thick A-pillars, somewhat limiting the view, uncontrolled automatic switch on passing light, high price auto.

The steering wheel in the parking lot and when driving in the city is very light, on the highway it becomes heavier, which is convenient. The suspension is soft, comfortable, but if you get into a hole, the impact is well felt. rear seats folded flush with the floor, a large flat surface is obtained.

In the 90s, SUVs gained immense popularity, even a brand that had not previously had a “civilian” SUV, in addition to the militarized “G” class, released the first generation “ML”. The production of Mercedes ML began in 1997, the model carried the W163 index, and the second generation began to be produced in 2005, the index is W164. The first two generations were sold around the world with a circulation of 1.1 million copies. The third generation of the Mercedes SUV is produced on a common platform with. The third ML received an index - W166. Mercedes is somewhat inferior in size to such cars as, or, but this is also an advantage in city traffic. The first two generations were very popular in the CIS, proof of this is the fact that every Mercedes sold in 2012 in Russia was exactly the ML - class.

Appearance:

The appearance of the new Mercedes B166, in comparison with its predecessors, can be characterized as more sporty. The car retained the branded rear pillar, which was also found on the W163. Compared to the previous -W164, the drag coefficient has dropped from 0.34 to 0.32 - a positive factor affecting fuel economy and acoustic comfort. In comparison with its predecessor, the length of the novelty has increased by 24mm, the width by 15mm, and the height by 14mm. In the basic version, tires of 235/65 R17, 255/55 R18 dimensions are installed, but twenty-inch tires are offered as an option for all-wheel drive Mercedes. The horizontal line of LEDs installed in the side air intakes looks very impressive.

Salon:

Words about the highest quality of performance will be superfluous. The car is equipped with the Pre-Safe system, which, if necessary (in the event of an impact), tightens the seat belts, closes the windows and the sunroof, and sets the seats in the optimal position from a safety point of view. An optional night vision system is offered - Night Viev Assist Plus, which is known for executive S-class sedans W221. The night vision system can recognize people. On the armrest, between the seats, there is a washer that controls all-wheel drive, the system has six modes: automatic - for daily driving, light off-road - dirt roads and country roads, serious off-road - terrain where you need to "climb", Winter - mode for roads covered with snow and ice, trailer - mode for towing a trailer, and mode - Sport. It's very interesting that sports mode available only to cars with the optional offroad package, as you know, good cross-country ability contradicts perfect handling, it seems that the Germans decided to create the most versatile vehicle. The suspension control buttons are also located on the armrest, it is interesting that they are even present in the base, on a car with spring suspension(settings are made using special shock absorbers). The basic equipment of the Mercedes ML W166 includes Thermatic dual-zone climate control and cruise control. The seat adjustment buttons are located in the Mercedes style - on the door cards. For the legs of second-row passengers, compared to the W166, 15mm has increased. The luggage compartment holds 690 liters.

Specifications Mercedes W166

The second EmElka from Mercedes in the back of the B166 was equipped with permanent all-wheel drive, as well as a start / stop system already in the basic configuration. A car with a spring suspension is able to overcome a ford with a depth of 50mm, and a Mercedes with an Airmatic suspension with the possibility of increasing the ground clearance up to 285mm can overcome a ford with a depth of 600mm. Versions with on&offroad package besides air suspension are equipped with additional body protection from below, as well as a cross-axle differential lock, not to mention the hill start assist system, as well as the hill descent assist system. The optional Active Cruve System minimizes roll in corners. the option is only available in Mercedes with air suspension. On off-road, the offroad button helps a lot, which allows the wheels to spin, and also includes higher gears for more high revs than usual.

As a gearbox for any of the versions, only one is available - a seven-speed automatic transmission 7-G Tronic Plus. In tests conducted by foreign journalists, the SUV withstood, without skidding, lateral acceleration with a force of 0.85g.

The base diesel - ML 250CDI produces 204hp and 500N.M of torque - this allows you to gain a hundred kilometers in 9s, and maximum speed, even with such the least powerful engine - 210 km. A more powerful diesel engine - 350CDI develops 258 forces and 620 N.M, with such a diesel engine an SUV picks up a hundred in 7.4 seconds, and on the highway it can develop 224 km. Petrol ML350 with a capacity of 306 horses and a torque of 370 N.M is gaining the first hundred in 7.6 seconds, the maximum speed is 235 km. The top-end ML500 develops 408 horsepower, which allows you to accelerate to hundreds in 5.6 seconds. ML 63AMG develops 525hp and 700Nm. ML63AMG accelerates to hundreds in 4.8s, the maximum speed is electronically limited to 250 kilometers.

Let's pay attention to the technical characteristics of the gasoline Mercedes ML350 W166 with a conventional spring suspension.

Mercedes Vito W638 - Mini Review and Specifications

01.05.2017

Mercedes ML (Mercedes-Benz W164) - the second generation of the popular M-class SUV from the German automotive Mercedes-Benz brands. The three-beam star on the hood has always caused a special thrill among most motorists, but not everyone can afford a new car of this class. At the moment, prices for a used ML have become more affordable, thanks to which motorists, for whom status and prestige play an important role, can fulfill their old dream. When buying a car at the age of 7-10 years, you need to be aware that such an acquisition is fraught with additional costs. But what they are, and what you should pay attention to when choosing a Mercedes ML (W164) with a range of secondary market, I will tell in this article.

A bit of history:

Work on the development of the Mercedes ML (W164) began back in 1999 and lasted 6 years. Steve Mattin worked on the car design project under the strict guidance of Peter Pfeiffer for more than 2 years. Testing of the prototype was carried out during 2003 - 2004 and ended in early 2005. The debut of the Mercedes ML (W164) took place in 2005 at the International Auto Show in North America. In April of the same year, mass production was launched. The car was assembled in the USA at the Chrysler plant located in Tuscaloosa (Alabama).

The novelty was built on a common platform with the GL-class, thanks to which it was possible to increase the size of the body and wheelbase compared to its predecessor (W163). In 2008, a restyled version of the car was presented to the public at the New York Auto Show. The main changes affected the front and rear bumpers, optics and radiator grille (it was enlarged and equipped with chrome inserts along the edges). The changes also affected model range, albeit slightly: updated diesel model ML 420 CDI, ML 280 CDI renamed to ML 300 CDI, ML 320 CDI to ML 350 CDI, and ML 420 CDI became known as ML 450 CDI. In 2009, the new ML 450 Hybrid SUV was introduced at the New York Auto Show. The production of the second generation of the M-class lasted 6 years and ended in 2011, and was replaced by a car Mercedes-Benz series W166.

Weaknesses Mercedes ML (W164) with mileage

The body of the Mercedes ML (W164) has practically no weak points - it is not afraid of corrosion, but only on condition that the car was not restored after an accident. But chrome elements do not tolerate the harsh realities of our winters and quickly become cloudy, after which they begin to bloom. When inspecting the car, be sure to check the tailgate, on most copies it is skewed (the screws holding the door hinge are destroyed). Also, there may be problems with door locks (mechanism breakdown, failures in the Keyless Go software). If there is moisture in the trunk, the problem most likely lies in the worn lamp seals. If you do not pay attention to this for a long time, over time, problems will begin with the SAM unit, since its electronic board is located in the right niche of the trunk.

Engine

Depending on the engine size of the Mercedes ML (W164), the corresponding index was assigned: gasoline - 3.5-ML350 (272 hp), 5.0-ML500 (308 hp), 5.5-ML550 (388 hp) 6, 2-ML 63 AMG (510 hp); diesel - 3.0-ML280 CDI, ML320 CDI (190 and 224 hp) since 2009 ML300 CDI (190 and 204 hp) ML350 CDI (224 hp), 4.0-ML420 CDI (306 hp).

Petrol

Most often in the secondary market there is a 3.5-liter gasoline power unit. Operating experience has shown that the engine is generally reliable, but, nevertheless, some shortcomings in it have been identified. As a rule, problems begin after the first 100,000 runs. The most common drawback is the wear of the cermet sprockets of the balance shaft. In the presence of a breakdown, in most cases, the error “ check engine". Also, a signal about the presence of a problem will be the “dieselization” of the motor, vibrations and metallic ringing when starting a cold engine. Another problem with characteristic symptoms is the stretching of the timing chain, this happens on a run of 100-150 thousand km.

Replacing the chain and shaft sprockets is a rather laborious process (to perform the work, it is necessary to remove the motor), which is why the cost of the work is quite high (1500-3000 USD). It is this fact that makes many owners get rid of the car at the first alarm bells (before buying, be sure to carry out a complete engine diagnostics). When performing repairs, it is advisable to immediately replace the chain damper, the magnets of the camshaft adjustment mechanism and the oil pump, so as not to pay twice for the removal and installation of the power unit. Often, owners of cars with a 5.5 engine (388 hp) also face the same problems, however, in this case, removing the engine is not required to eliminate most of the shortcomings, which significantly reduces the cost of repairs. Closer to a run of 150,000 km, many owners of the Mercedes ML (W164) have to change the exhaust manifold due to problems with the vacuum rods of the adjustable dampers (on copies after 2007, this problem was eliminated). A signal about the presence of problems will be walking speeds at idle.

All gasoline engines suffer from oil leakage, most often leaks appear on the plastic plugs of the cylinder head. Also, on cars with a mileage of more than 100,000 km, oil smudges can be found at the junction of the filter housing and the oil cooler heat exchanger due to a leaky seal. Owners of pre-styling cars often encountered such a problem as the “freezing” of plastic swirl flaps intake manifold, because of which it was necessary to change the entire manifold. When using low quality fuel, catalysts die prematurely. The problem is solved by replacing them with flame arresters. The 5.0 engine has proven to be the most reliable, of its shortcomings, only high flow fuel and high transport tax, otherwise, there are practically no complaints about him. The car uses 2 batteries, they usually last about 5 years, to replace them you will have to pay almost 100 USD. for every. Once every 100,000 km, you have to change the starter retractor relay, they ask for 40-70 USD for a replacement.

Diesel Mercedes ML (W164)

On diesel engines, during long trips, a decrease in the life of the turbine is observed (during normal operation, the turbine nurses up to 300,000 km). The main reason for premature wear of the part lies in not the best location (installed in the place where the temperature is highest). The cost of the turbine will surprise even wealthy ML owners (about 2000 USD). Also, the rapid appearance of soot on the exhaust manifold can be attributed to the common disadvantages of diesel engines, which eventually begins to fall off and can “kill” the turbine. Significant costs may be required for untimely replacement glow plugs. The fact is that when a candle burns out, it is unlikely that it will be possible to unscrew it naturally, and in order to replace them, you will have to remove the engine head and drill out the burnt candle.

If extraneous vibrations appear on the car, you need to pay attention to the crankshaft pulley clutch, it may have begun to fail. Also, due to the weight power units quite often you have to change the engine mounts. Diesel engines equipped with the Common Rail system, which is an advantage and, at the same time, a disadvantage. The advantages include the efficiency of motors. The disadvantages are the sensitivity of the system to fuel quality. If there are no good gas stations in your area, you need to be prepared for frequent expensive repairs to injectors, high pressure fuel pumps and the EGR valve.

Transmission

Mercedes ML (W164) is equipped with only automatic transmission 7G Tronic. The automatic transmission has a number of problems, most often jerks when starting, accelerating and stopping. In most cases, flashing the transmission control unit helps to cope with this trouble. The valve body is not famous for its reliability either, its resource rarely exceeds 100,000 km. The main signal about the presence of a problem will be jerks during acceleration. If you do not contact the service in time, you will soon need to replace the clutch package. Replacing the valve body costs 1500 USD, but you can save money by buying a repair kit, in which case it will be possible to fix the problem for 500 USD. By 150,000 km of run, on most instances, the oil pump “dies”, if it is not replaced in time, then from high temperatures will fail the electronic unit ECM control. All these defects, except for one - the leaks of the "machine" cooling tubes, were eliminated after restyling.

Of the shortcomings of the system all-wheel drive problems with the front axle gearbox (100-150 thousand km) can be identified. The imminent death of the gearbox will be notified by vibrations and hum. To fix the breakdown, you will have to pay 500-700 USD. The front propeller shaft does not live much longer either. On a run of 120-170 thousand km (depending on operating conditions), bearings begin to buzz. Often, the soundtrack can also come from the outboard bearing, which dealers, as a rule, change in tandem with the cardan shaft; for non-officials, the bearing can be changed separately. At active use all-wheel drive system to 100,000 km of run the chain is stretched transfer box. The disease is accompanied by cracking and grinding under stress. The razdatka, like the automatic transmission, with proper operation does not cause serious problems up to 200-250 thousand kilometers.

Suspension reliability Mercedes ML (W164)

This model is presented on the market with two types of suspension - independent spring and air suspension. If we talk about which of the two types of chassis to give preference to, then, in terms of reliability, the usual suspension will be preferable, in terms of comfort - pneumatic. In a spring suspension, most often you have to change the stabilizer struts, about once every 60-70 thousand km. After 50,000 km, ball bearings begin to creak, and after 20-30 thousand km they have to be changed. Once every 100-120 thousand km, replacement is required: shock absorbers, wheel bearings and silent blocks of levers (they change as an assembly with levers). The rear suspension does not require intervention up to 150,000 km, only shock absorbers can be an exception (their resource rarely exceeds 130,000 km).

Mercedes ML (W164) air suspension repair will have to be done every 80-100 thousand km. The cost of one original front pneumocylinder is about 1000 USD, the rear is about 500 USD. If, in time, you do not change worn air bellows, this will negatively affect the life of the compressor, the replacement of which costs 2000-3000 USD. To check the condition of the pneuma, raise the machine to the maximum level and leave it in this position for half an hour (the machine should not lower a single mm.).

Often, when driving on a rough road, extraneous knocks are heard from the suspension, check the fastening of the front pneumatic elements to the racks - the fasteners weaken over time and require a banal broach. steering rack generally reliable and able to last up to 200,000 km without repair, but there have been cases when it started to flow at a range of 100-120 thousand km (it is eliminated by replacing oil seals and seals). Weaknesses in the steering are: thrust (go up to 90-110 thousand km) and the steering shaft cardan. Also, there is a complaint about the reliability of the power steering pump, when replacing the pump, it is recommended to change the tank as well, since the filter mesh quickly clogs in it. Brake system reliable, but, due to the considerable weight of the car, brake pads wear out quickly enough (30-35 thousand km).

Salon

The quality of the interior finishing materials of the Mercedes ML (W164) leaves an ambiguous impression. The plastic from which the central panel and other interior elements are made is of high quality and retains its original appearance for a long time. And, here, the seat trim does not correspond to the class of the car, the fact is that the seats are made of eco-leather, which cracks and begins to climb by 100,000 km. As for the electrics, over the years, it begins to present unpleasant surprises, such as malfunctions in the climate control (“servos” are buggy). electronic dampers), sound signal and standard audio system (does not return discs). Eliminating even minor problems in electronics is not cheap.

Outcome:

Mercedes ML (W164) is generally sufficient reliable car, however, copies released after 2009 are considered less problematic. Unfortunately, air suspension presents a lot of problems, and the cost of individual spare parts and work exceeds all reasonable limits.

If you are the owner of this car model, please describe the problems that you had to face during the operation of the car. Perhaps it is your review that will help readers of our site when choosing a car.

To begin with, let's decide what can be called a hi-fi level system, and what falls short of this understanding. In the environment of car audio, certain stereotypes have developed on this topic. And I will present them here.

Stock-style system (when all equipment is installed in regular places) cannot be hi-fi level. Many people think so, and for good reason. The main disadvantage is the location of regular speakers. Despite the fact that the acoustics are changing to high-quality ones, regular grills remain. Few of the owners are willing to go to the bottom of the alteration, for example, door skins, in order to properly place the non-standard midbass.

The same story with the tweeters (tweeters). Often, a regular place is not the best option for placing a tweeter, but few people want to go for a radical revision.

It is for this reason that most installs (and about 90% of installs are made in the Stock style by all studios) do not reach a serious hi-fi level. This is not just a theory, but a practice proven in car audio competitions.

The other extreme is serious hi-fi, and sometimes Hi-end. There is no point in talking about this. I'll just say that in serious systems, the price levels for equipment are so serious that any sane person, having heard how much, for example, a set of top acoustics from Focal, will simply twist his finger at his temple (secretly -under a million rubles )

But there is also golden mean. Regular hi-fi. Let's call it that. Or - the initial level of a serious approach to car audio. This is when a system is built that takes into account to the maximum both the wishes of the client regarding the preservation of the interior and free space and the requests of the installer, who needs space and something needs to be redone.

It is about such a system based on the Mercedes ML in the back of the W166 that I will tell.

The car was once bought in the simplest (in terms of sound) equipment. There was a simple command and 2 sets of acoustics. Over time, the owner did only one, but the right action - he changed the simple Command to Command 4.5 NTG. The difference is not only in the quality of these devices, but in the fact that the 4.5NTG has an optical MOST bus output. And this means that you can remove an almost perfect broadband signal from it and apply it to new system. Actually, optics is, as it were, an ideal signal transmission medium (pure figure, no distortion or interference).

At the time of the visit to our studio, the client did not think about the Hifi system. The conversation began with the classical system. Here's one:

But at the time of the conversation, it was decided that we would build the initial hifi.

Here is the scheme

the main interesting technical solutions are described in our , which was conducted on this car at the time of work. Here I will talk about the main points of the installation and show what happened at the end.

So the car

the regular location of the mid-bass speakers is the same in almost all cars - the lower front part of the door. The location of the tweeters is different for everyone. at Mercedes they are in plastic overlays - "triangles" of rear-view mirrors. Those. the car has 2-component front speakers

the same for the back door. And also - 2-component acoustics

in design - complete harmony. That is why few people want to interfere in it and change something.

and here is the trunk. The trunk is the place where spears always break when discussing a project with the owner. Many people want a lot of bass, with a margin, and at the same time they are not ready to give anything in the trunk. I'm talking about the place. You can't deceive physics for a 10-inch subwoofer, you need to take at least 15-20 liters of volume in the trunk. And for a 12-inch subwoofer - even more. In this case, a stealth enclosure for a subwoofer comes to our aid. An enclosure that we can hide behind the skin of the car and install a subwoofer speaker in it. We save trunk space and get bass. But stealth is not cheap.

We dismantle the doors. Without complete soundproofing of 4 doors (this is the minimum), you should not talk about installing car audio at all. If someone tells you that you can just change the acoustics in a car and you will get a noticeable difference, feel free to leave this place. Throw money away.

The photo shows the standard vibration isolation of the rear door

We remove the command and send it to the Erta service to decode and activate the MOST output

the photo shows the MOST connector above the yellow fuse

dismantling and salon, tk. we will do soundproofing floor and trunk.

We came across a car with air suspension, which means that 2 receivers from it settled in the trunk. in the right sidewall (where we usually put amplifiers in such Mercedes) and in the trunk subfield. This restricts us quite a lot in place.

in the left sidewall there is a place for placing equipment. But this is if we talk about a simple classic circuit on 1 or 2 amplifiers. We have three of them + a processor.

here is another receiver

regular vibration isolation of the floor does not stand up to criticism

but there is also positive sides in this car - under the driver there is a large niche in which we will put part of the equipment

As I wrote above, we carry out a fairly serious noise and vibration isolation for this machine

Trunk

doors

lining of all doors and trunk

here is the standard soundproofing of the door trim. A piece of pressed synthetic winterizer

and here is the result of our processing. The gray material is noise isolation. Under it, the skin is also treated with vibration isolation. And along the perimeter - Antiskripom

Well, now I'll tell you about the music.

For the subwoofer section, we chose the best subwoofer according to EISA for 2013 - Audison Voce AV10. Although not the smallest speaker, it works great in volumes from 17 liters.

and this volume (even more - which is better) we find in the left side trim. We start manufacturing a stealth hull from composite materials: resin + glass mat

frontal part of the case - plywood 21 mm

the speaker has a fairly large magnetic system and because of this it has to be moved a little to the right, which leads to the modernization of the standard casing

in order to beat it beautifully, we are making a new grill cover that will cover the subwoofer

it is completely transparent

the car will have three new amplifiers. We need a lot of good food. Therefore, from the battery that stands under the passenger, we pull the Stinger power cables of 2Ga caliber

we pull to the universal distributor, which stands under the rear sofa. Here are all the fuses for the amplifiers. If something closes somewhere, then the fuse "flies" first. From the distributor, power of various calibers is distributed throughout the car - to amplifiers

the main fuse, which protects the entire power circuit, is installed right next to the battery.

in the niche under the driver, we are building a two-story podium, which will accommodate almost all the equipment. In the subfield there will be an Alpine monoblock that rocks the subwoofer

above it are placed: the Audison Bit One processor and a 4-channel amplifier for the front midbass and rear acoustics - Hertz

niche is closed. For cooling, we cut two low-noise fans into the lid: one is an exhaust fan, the other is a supply fan. Thus, we ensure a constant circulation of air in this volume and cooling of the amplifiers

in a regular carpet for this we make ventilation holes

but we have one more amplifier. It works with tweeters / midrange speakers front acoustics. And this part of the story is just about HiFi. Many car audio lovers who are not particularly versed in the topic of the question ask - why did you implement the mid/high range on passive crossovers? After all, you have an 8-channel processor. Of course, yes, there is, but only if you look closely at the diagram, you can see that we have REAR speakers in the system. This is the wish of the client. It is believed that rear speakers are not needed for high-quality music playback, but only for multimedia formats (watching movies and concerts), but if someone drives behind, then many owners want to keep these speakers.

In this case, we do not have enough channels to implement the "per-channel" scheme and we reduce 4 channels into two. And to separate the signal, a regular passive crossover is installed, which came complete with CDT Audio ES632 acoustics. Such a scheme is called in our jargon - "semi-channel" or - "2.5"

and this is where we do the "feint with the ears". The amplifier that will play on the midrange / tweeters, although small (CDT Audio MXMX1502), still has dimensions and needs to be placed somewhere. Under the driver, he just does not fit. In addition, we have 2 crossovers of very decent sizes. And we decide to put all this link - under the subwoofer, in the left wing. Moreover, leaving the possibility of operational adjustment of passive crossovers.

It looks like this (crossovers are closed with regular grids, and on top - with a false panel)

the processor control panel settled in the place where the ashtray was. We are for car audio and healthy lifestyle, and smoking is a fight!

now a minute of sparkling humor and jokes.

This is standard acoustics from Mercedes Benz ML, which costs, please note, from 2.5 million.

Ours is much more serious. To install new midbass and rear speakers, we make adapter rings

they will be installed on glass sealant (to enhance contact)

and on bolts

front midbass are connected to acoustic wiring with spring clamps (this is an indicator of serious acoustics, by the way)

and finished look like this

rear coaxial acoustics CDT Audio HD6EX (in the CDT Audio CL61CV scheme, but it was not there and we chose another one) is soldered to the wiring

as interconnect cables in this installation, we use a pre-top cable from Tchernov Cables and Chernov RCA connectors

ML machine is quite convenient in terms of speaker wiring. You can easily "pass" through the standard connectors in the doors and lay the cable without breaking: from the amplifier to the speaker. Which positively affects the sound quality (as we remember, we have a hi-fi system). All wiring is tinned copper from Stinger

all wiring fits into the "snake"

and now we have smoothly approached the hifi part of the system - this is mid/high front acoustics. In the photo below - a midrange speaker, which in a three-component system scores for the most difficult range: 500 Hz - 4 kHz. In this range we have many instruments and vocals. It is believed (and not just so) that a three-component system is the maximum that can be implemented in a car. And in home acoustics, the situation is about the same.

You have already seen the size of such a speaker. It is unrealistic to put it in some regular Mercedes place. There are simply no such places. Therefore, we follow the classical path and place the midrange / tweeter link on racks windshield with a slight turn into the salon

the direction of the speakers - to the opposite center pillars. Turning the speakers helps us finally set up the system with maximum quality and "build" the desired sound stage. Wide and deep. For the sake of this, all this hi-fi is conceived

racks are manufactured according to the classical technology: supplex + resin + glass mat + putty and hours of sanding

upholstered in black Alcantara

speakers soldered to wiring

this is the result

and take another look at the trunk, which we saved completely

To set up such systems, we involve professional "hearers" who have authority in the car audio environment. Such systems need to be "opened" in terms of sound and this requires talent and experience.

Here is the frequency response of an unheated system immediately after tuning

Frequency response of the left and right channels

Frequency response by components (sub, midbass, midrange, treble)

after warming up the system, we will "comb" the system a little

third generation mercedes-benz m-class(factory index W166) was officially presented at the Frankfurt Motor Show in autumn 2011. New Mercedes ML appeared in Russia in the spring of 2012. In our review, we will try to understand the technical characteristics of the 2013 Mercedes-Benz ML crossover (engine, gearbox, 4Matic all-wheel drive, Airmatic air suspension), evaluate dimensions body, the possibility of equipping with rims and tires, choose the color of the SUV, sit in the cabin, look into the trunk, conduct a test drive, find out prices and find out the nuances of operation and fuel consumption. Our traditional assistants will be photo and video materials, analysis of numerous reviews of the owners of the Mercedes M-class of the 2012-2013 model.

With the change of generations, the German premium crossover SUV Mercedes M L (W166) retained the platform of the previous generation of the model (W164), but slightly increased in size. External dimensions dimensions The bodies of the new ML are: 4804 mm long, 1926 mm (with mirrors 2141 mm) wide, 1796 mm high, 2915 mm wheelbase.

• Ground clearance Mercedes Benz ML - 191 mm or 202 mm for crossovers with spring suspension, adjustable for cars with air springs clearance from 180 mm to 255 mm.
• Depending on the wishes of the car owner, the car can be shod in tires on light alloy disks different sizes: 235/65 R17, 255/55 R18, 255/50 R19, 265/45 R20, 265/40 R21 and it is even possible to install rubber 265/35 R22, 285/30 R22, 295/30 R22.

A wide palette is offered for painting the body colors: non-metallics - Black and White Calcite, and metallics - Black Obsidian, Tanzanite Blue, Tenorite Gray, Iridium Silver, Palladium Silver, Pearl Beige, Citrine Brown, the cost of the color is included in the price of the car. For a special metallic White Diamond, an additional payment of 53,789 rubles is required.
Let's evaluate the appearance of the new Merce Emel visually. It's no secret that the crossover is market oriented. North America and, of course, German designers tried to make the car truly American - plump, with a lot of chrome elements. The front part of the body of the Mercedes-Benz M-class (W166) is similar to the design of a larger and more expensive one. Neat almond-shaped headlights (xenon) are located high on the ledges of the front fenders, a large radiator grille with three horizontal lintels and a large Mercedes logo, a huge front bumper with multi-level air intakes, bright chrome inserts and stylish LED strips for daytime running lights. The hood rises above the general architecture of the front end, giving the appearance of the car a solid haughty look.
When reviewing the body from the side, we observe the familiar proportions of previous generations of the M-class, but the sidewalls of the body now prescribe more pronounced stampings, the window sill line has become higher, and original solution the rear roof pillar and an increase in the glazing area of ​​​​the stern gives the body monumentality. Rear end looks a little heavy, but at the same time solid. Huge chandeliers of overall lighting equipment go far to the sidewalls, a large tailgate with panoramic glass, a powerful bumper is trimmed from below and decorated with a chrome insert.
We would like to note that the body of the crossover SUV is made of high-strength and heavy-duty steels, aluminum (hood and front fenders) and magnesium alloy parts (crossbar between the front pillars). The design of the power frame (cabin capsule) has become more rigid, while the deformation zones have increased, designed to minimize the impact on passengers in the event of an accident. As standard, the new ML is equipped with an active hood that can rise when a pedestrian is hit. Also, the developers managed to reduce the drag coefficient to the air flow to 0.32 Cx.

Salon new Mercedes-Benz ML 2013 meets its five passengers with high-quality finishing materials (fabric, soft plastics, artificial and natural leather, wood or aluminum inserts), there are a lot of variations. Power front seats with heating (ventilation option) are comfortable and comfortable, but with insufficient lateral support. A grippy four-spoke steering wheel dashboard consisting of two dials in deep wells, only the black-and-white multifunctional screen seems somewhat out of place in a premium car.
The controls are placed in a traditional Mercedes style: on the steering column on the left side is a multifunctional lever (turn signals, wipers, high beam), below it is the cruise control knob. With right side joystick automatic transmission. At first glance, it seems that it is very difficult to deal with the switches, but after a couple of days you understand how everything is correctly and logically placed. The design of the front dashboard and center console echoes the GL-class.
In the basic version, the top of the console is crowned with a monochrome 11.4 cm screen of the Audio 20 CD audio system (CD MP3 AUX USB Bluetooth), for an extra charge, an advanced Comand Online multimedia system with a 17.8 cm color screen (navigation, DVD) and Harman Kardon Logic Bang and Olufsen Beo Sound. Below the dual-zone climate control unit (three-zone option), the console goes into a high tunnel, on which the washers for controlling suspension settings and electronic systems are conveniently and correctly located. Seats in front in all directions with an enviable margin, the driver and passenger of large build will not interfere with each other. The rear row of seats will comfortably accommodate three passengers, the separate backrest changes the angle of inclination, as an additional equipment for the rear riders, you can install a multimedia system with two color screens. Legroom, headroom and width may not be record-breaking, but it will be easy to sit comfortably.
Impressive huge luggage compartment new ML. With five crew members, the trunk of a car is capable of absorbing 690 liters of cargo, when transforming the back row, a flat cargo area is formed with a width of 1034 mm and a length of 1700 mm to 1833 mm (depending on the position of the first row seats), with a maximum possible volume of 2010 liters.
The salon is bright, comfortable and cozy, the interior pleases with thoughtfulness, a lot of containers for storing small items and a rich level of equipment. But, alas, the main functions of comfort and systems that make driving easier are available as options. And there is something to order: Distronic Plus (active cruise control with the ability to stop the car), Intelligent Light System ( adaptive system lighting), night vision system Plus, automatic valet parking, rear view camera, tracking systems road signs, driver status (Attention Assist), centerline crossing and blind spots, Keyless-go (keyless entry and push-button start), a panoramic glass sunroof with a sliding sunroof and, of course, accessories for the Mercedes-Benz ML.

Specifications Mercedes M-Class 2012-2013: basic equipment The M-Class crossover (W166) is equipped with 4Matic permanent all-wheel drive, ESP, 4ETS, ABS and ASR ensure its correct operation.

In Russia, the 2013 Mercedes-Benz ML is offered with one diesel and three gasoline engines.

• Diesel V6 ML 350 CDI 4Matic (258 hp) accelerates a car weighing 2175 kg to 100 mph in 7.4 seconds, top speed 224 mph, fuel consumption in the combined cycle according to the manufacturer will be 6.8-7.4 liters. An analysis of the reviews of the owners speaks of real consumption fuel in the city at the level of 11.5-12 liters, and in mixed mode 8.5-9.5 liters.

Petrol engines

• V6 ML 350 4Matic (306 hp) will provide the dynamics of a car weighing 2130 kg to the first hundred in 7.6 seconds at a top speed of 235 mph. Passport fuel consumption ranges from 7.4 liters on the highway to 11.3 liters in the city, in real conditions the engine consumes 13-14 liters in mixed mode, and in urban driving conditions the consumption can rise up to 15-16 liters.
• V8 ML 500 4Matic (408 hp) shoots a crossover weighing from 2130 kg to hundreds in 5.6 seconds, acceleration will slow down when it reaches a maximum value of 250 mph. Based on the feedback from the owners, we can conclude that the engine actually consumes 12-13 liters on the highway, and in urban conditions at least 17-18 liters of gasoline.
• The 5.5-liter V8 Biturbo ML 63 AMG (525 hp) shoots the car from AMG to 100 km / h in 4.8 seconds, the maximum speed is electronically limited to 250 km / h, you can remove the limiter and then the maximum speed will be 280 km / h. Factory data on fuel consumption from 9.6 liters on the highway to 15.7 liters in the city, in real operating conditions result in average consumption fuel, which rarely falls below 17 liters, in the city can be more than 22 liters.

Test Drive Mercedes M-Class 2012-2013: it’s simply not possible to drive the new Emel calmly and measuredly, even the power diesel engine in excess, the machine is fast and willingly switches up, the suspension settings are pronounced sporty. With a mass of over 2 tons, the crossover is obedient and adequate - the new ML gives drive, speed and adrenaline in the blood. The most interesting thing is that despite the correct and stable behavior on paved roads, Merce did not lose its off-road potential, although it lost the rear differential lock. Of course, off-road storming is better on a crossover with air suspension and the On&Offroad package.
According to statistics, only 1% of Mercedes Benz M-class owners are ready to drive their beautiful and expensive car into impassable mud, where a thoroughbred Mercedes will climb and drive forward until at least one wheel can find proper support. You can also safely force a water barrier up to 60 cm deep. Of course, the M-Class is not, but for the remaining 99% of the owners of the off-road capabilities of the car, it will be more than enough.
I would like to say a few words about typical breakdowns of Mercedes in recent years: the main problems will be delivered by air suspension elements, an automatic transmission electronic control unit, engine sensors and electrical equipment. Given these possible shortcomings and malfunctions, we can assume how much it will cost to buy spare parts, diagnose and repair a Mercedes M-class. It is clear that they will also cost a pretty penny service maintenance and tuning ML, which is usually carried out by a car dealership (official dealers).
