Interruptions in engine operation. Opel Astra J

Opel Astra fourth generation(with the J index) debuted in 2009. Its attractive lines make it stand out from its dull predecessors. First-hand cars are very rare. Among the cars imported from the West, the dominant ones are those restored after an accident.

Chassis

In addition to the beautiful “body”, Astra IV received a number of new technical solutions. An example would be suspension design. At the front there are time-tested “McPherson struts”, and at the rear there is a regular beam or a Watt mechanism supplemented with a system of levers. The latter can significantly improve road performance, but significantly increases the cost of repairs. Some owners of cars with innovative rear suspension complain about its loud operation, especially on short transverse joints and bumps.

Sports versions can be equipped with FlexRide adaptive shock absorbers of variable stiffness. However, their service life is shorter than that of conventional shock absorbers.

Massive lower wishbones allow you to change the silent blocks separately. But spherical bearing updated only with the lever. The saving grace is that all elements of the lever are durable.

Interior for a long time saved in good condition. Opel is characterized by the presence of a large number of buttons and switches. There are almost 50 of them on the center console and steering wheel alone.

Another example of technical innovations is electric parking brake. Fortunately (from the point of view operating costs), this solution is offered only as an option (in expensive trim levels, for example Cosmo).

The parking brake mechanism quickly rusts during prolonged inactivity (non-use) and in wet weather.

Over time, the rear brake calipers may rattle. Often the disease can be overcome by filling the caliper guides with lubricants. Souring also occurs brake calipers. For repairs, it is necessary to disassemble and clean the mechanism.

The Opel Astra J was offered with two power steering options - electromechanical and hydraulic. You can determine the type of amplifier by opening the hood. If there is an electric power steering, there is no reservoir and amplifier pump. If there is power steering, there is a reservoir and a pump located on the left side of the engine.

Engines

The high cost of used Asters forces most buyers to look for cheaper options with modest engines. Due to the relatively large Opel weights Astra IV (130 kg heavier than Opel Astra III), base 1.4-liter gasoline engine 100 hp - far from the best the best choice. He is forced to work hard, and therefore consumes a lot of fuel - up to 11 l/100 km. Ultimately, this will affect the resource. The most optimal, in terms of operating and repair costs, is the 1.6-liter 16-valve naturally aspirated A16XER.

Both motors are quite reliable and durable. The timing of the 1.4-liter naturally aspirated engine is driven by a chain, and the 1.6-liter engine is driven by a timing belt. In the basic 1.4, ignition coils sometimes fail. The cause is corrosion inside the rod. The malfunction is accompanied by vibration. It is important that in case of failures in the ignition system, when the engine runs on fewer cylinders, the catalytic converter is not destroyed.

The larger 1.6 uses a phase control valve mounted on the intake and exhaust camshafts. Sometimes he starts making noise. The first thing to go, as a rule, is the intake camshaft phase regulator.

1.6-liter petrol engine with 115 hp. There are not enough stars from the sky. But at least it doesn't cause problems.

Turbo engines with a displacement of 1.4 and 1.6 liters have promising characteristics. Even the 120-horsepower 1.4 Turbo copes confidently with the Astra, thanks to its good elasticity.

The 1.4 Turbo has a fatal defect - cracking of the pistons. The problem occurs in the range of 50-100 thousand.

Problem with the Opel Astra 1.4 turbo engine

km. In this case, the engine stops pulling and begins to consume a large amount of oil. The larger 1.6 Turbo does not show such weakness.

Diesel versions were not officially supplied to Russia. The selection of such specimens must be approached carefully. All of them are equipped particulate filter. The most preferred turbodiesel is the 2.0 CDTI - the successful successor to the 1.9 CDTI. Such cars are very rare, and also very expensive.

Opel Astra with 1.7 CDTI is much cheaper. Average consumption fuel ranges from 5.5-7.5 liters per 100 km. For everyday driving, this advanced Isuzu unit is sufficient. Only sometimes does the differential pressure sensor of the particulate filter or the exhaust gas recirculation valve fail.

The 1.6 CDTi appeared in 2014. It uses Denso injection system. Malfunctions are rare here, but at the same time, some owners had to change the turbocharger under warranty.

Incorrectly seated window seals cause loud aerodynamic wind noise at speeds over 100 km/h.

Headlights often fog up, and a software error causes the automatic headlight leveling to malfunction.

If you operate the lever quickly, it may turn on instead of the first reverse gear. Eliminating the defect involves re-adjusting the gear selection mechanism and installing a new rocker.

On Astras 2010-2011, the clutch pedal return spring breaks. Opel carried out a service campaign to eliminate the defect. In addition, the shaft bearings of the six-speed M32 manual transmission are not durable.

An incorrect operating algorithm of the on-board electronics control module quickly discharges the battery if you leave the low beams or side lights on for a long time. Opel has improved the software.

In cars with 2.0 CDTI (engine code A20DTH), injector malfunctions occurred due to errors in the engine control unit software. Updating the software solved the problem.

The exhaust system is prone to premature corrosion.

engine power limited Opel Astra

Unfortunately, most sedans in the popular golf class look rather unlucky. The trunk seems to have been hastily attached to the body. Fortunately, there are exceptions that, by their appearance, on the contrary, attract and encourage choice.

Most automakers create models that are similar to each other, regardless of class and price category. Therefore, it is sometimes even difficult for inexperienced car enthusiasts to immediately determine what kind of car is in front of them. Fortunately, Opel took a different route. Therefore, the Opel Astra Sedan cannot be confused with the big Insignia. In reality, Astra is much nicer than its older brother. Elegant lines, wheel disks tasteful and interesting Brown color with a golden tint allow you to perceive the car as a prestigious sedan.

Jokes aside, the Opel Astra Sedan really looks beautiful. There is nothing to complain about here, every detail is well thought out. Even the optional spoiler on the trunk lid looks elegant. This is one of the most beautiful sedans currently produced.

If the simple and elegant design delights, then inside there is one significant drawback - ergonomics. The abundance of buttons on the center console causes a headache. There are several buttons that I could not remember even after a week of intense “communication” with the car.

A million buttons is one thing, but there is also something else - control of the on-board computer. In order to confirm that the function has been selected correctly, you need to press not in the usual place - the center of the large round button, but press on the chrome ring surrounding it.

Malfunction in Opel Astra

This decision, although unusual, is to some extent not without logic. This reduces the likelihood of accidentally pressing the button.

There are no complaints about the front panel. Very pleased with the attention to detail. The elegant steering wheel fits nicely in your hands, and the instruments are easy to read. When turned on sport mode The color of the instrument illumination changes from white to fiery red. The handles and gear lever are also illuminated, which looks very nice at night.

The interior of the test Opel Astra Sedan was enriched with beautiful brown leather seats, which were combined brilliantly with chocolate-colored plastics and light leather elements on the dashboard and door panels. This design would be the envy of Bentley, and this is by no means ironic. Of course, the quality of the materials here is much worse, and some of the plastic creaks. And even despite this, the interior still makes a very pleasant impression. In addition, the front seats and steering wheel are heated. Dual-zone climate control and an electric sunroof will ensure a comfortable stay.

When it comes to the level of equipment of the car, it becomes obvious that the manufacturer has not spared any equipment for this example. Navigation, Bluetooth, CD/MP3 radio are just the beginning. The Astra Sedan has rain and light sensors, automatic daytime running lights, a traffic sign recognition and Line Asistant lane keeping system. In addition, the Opel was equipped with very good cruise control, which does not deactivate after pressing the clutch pedal, as often happens. On-board computer suggests the appropriate moment to change gears. Indeed, it is amazing how many gadgets can now be ordered for such a small and not very prestigious car, which is considered an Opel. And it's really great!

There is plenty of space in the cabin, although there could be a little more, especially in the second row. Passengers taller than 185 cm will experience some discomfort due to the tightly hanging roof over their heads. There is not much legroom, but you can hold out for a while until a person over 190 cm tall sits in front.

Of course, for every sedan the trunk volume is considered important: 460 liters is very good result. However, there is a small drawback. The trunk lid has rather large hinges that are not hidden anywhere and can come into contact with luggage. The trunk can only be opened using a key or a button in the cabin.

Under the hood of our Opel Astra Sedan is a 1.4-liter engine that, thanks to a turbocharger, produces 140 hp. and 200 Nm of torque. It would seem that so much power is too much for a car of this class. But that's not true. Firstly, Opel cars have been suffering for many years from the disease of the twenty-first century - excess weight. So the sedan weighs 1490 kg, while its direct competitors are much lighter: Volkswagen Jetta with a similar engine - almost 130 kg, and Ford Focus- almost 200 kg. Therefore, despite good characteristics engine, there is no excess power felt. The situation is slightly improved by the sport mode: reactions to the gas pedal become more lively, but overall the car still remains sluggish. The technical specifications speak for themselves. Acceleration to 100 km/h takes 10.2 seconds.

For those hungry for more in the engine line, there is a more powerful 1.6-liter unit, which, with the help of a turbocharger, develops 180 hp. But something tells me that this won’t be enough...

Fuel consumption is unsensational. On the highway, the recorded minimum is 6 liters per 100 km, and in the city at least 7-8 liters. On crowded streets and intersections with traffic lights, the ECO mode, which is nothing more than a Start/Stop system, helps save fuel. Her work is controversial. The engine stalls before the car comes to a complete stop, which is especially annoying in slow-moving traffic.

The sedan is equipped with an adaptive FlexRide suspension with the ability to adjust the stiffness using the SPORT and TOUR buttons. In normal mode, the Opel Astra Sedan is very comfortable. And this despite the 18-inch wheels. Every bump is stoically swallowed, and silence and calm reign in the cabin. The sedan is also not afraid of turns. After activating the sport mode, the suspension becomes stiffer, but there is no significant difference. The steering is a little worse. The steering wheel is too light. But in this case, the SPORT mode almost completely solves the problem - the steering wheel is filled with pleasant force. When you press the TOUR button, the suspension supposedly becomes softer and is ideal for roads that are not too twisty. But again, not much difference is noticeable.

Due to large trunk you need to be careful when maneuvering backwards. Review via rear window not too good. Parking sensors solve the problem, and those who don’t believe in them should order a rear-view camera.

The Opel Astra Sedan is a real sedan, not a hatchback with a trunk riveted to the rear. In addition, he is one of the most beautiful representatives of his class. Delightful design accompanied good quality execution. The only serious drawback is excess weight, from which, we hope, in the next generation Astra will get rid of it completely.

Automatic transmission device 6T40 for Opel Astra J

Opel Astra J cars are equipped with a six-speed automatic gearbox 6T40, which provides the choice of the optimal gear shift mode for almost any driving style and road conditions.

The 6T40 automatic transmission is configured according to a traditional planetary design with clutch braking and is connected to crankshaft engine through a torque converter.

A special feature of the Opel Astra J automatic transmission is the ability to switch from a fully automatic control mode to a semi-automatic mode, in which the driver, depending on driving conditions, can forcibly block automatic switching to higher gears.

The automatic transmission control drive is cable driven. Lever 7 (Fig. 150) of the gearbox control selector is installed in the same place on the floor tunnel as the manual transmission control lever.

The selector lever is connected to lever 11 of the control unit on the gearbox by cable 4. The differential design is completely similar to the differential manual box transmission

Diagnostics of automatic transmission Opel Astra J

There are several operations and verification tests to help identify faults earlier and more accurately. However, we strongly recommend that you do not abuse them and follow safety precautions to avoid damage.

If the results of a vehicle test are in doubt, you should contact specialists for advice. The simplest is the time delay test.

While the engine is running Idling When moving the drive mode selector lever to "D" or "R" from the neutral position, there must be a time delay before activation is felt. Purpose of the event this test— checking the performance of gearbox components and mechanisms.

For safety purposes and to prevent breakdowns of the 6T40 automatic transmission of the Opel Astra J:

- before performing the test, warm up the box well, the temperature automatic transmission should be at least 50-80 "C;

— to achieve high quality testing, it is necessary to carry out at least three measurements and determine their average value;

— to maintain high performance of the automatic transmission, take one-minute breaks between measurements.

The time delay test for the Opel Astra J automatic transmission is carried out as follows:

Fully raise the parking brake lever. Start the engine.

Check the engine idle speed in the “N” range. The engine idle speed should be 750-900 rpm. If idle speed If the engine does not meet the standard, the measurement results will also be incorrect and the test will have to be repeated.

Move the driving mode selector lever from the “N” range to the “D” range. Using a stopwatch, measure the time from the start of the handle movement to the moment it triggers.

Using the same method, take measurements when switching from the “N” range to the “R” range. In this case, the time delay should not exceed 1.5 s.

When assessing the results of the test, you must assume that if there is any breakdown, the response time can only increase.

Only a professional can find out the cause and fix the malfunction, so you should urgently contact the appropriate service center.

The parking test is also quite simple.

Its purpose is to check the performance of the engine, torque converter and gearbox as a whole.

To ensure safety and avoid breakdowns of the Opel Astra J automatic transmission:

— it is necessary to carry out the test in a sufficiently light and wide area.

— the test must be carried out by two technicians working in pairs: one of them must observe the wheels and their stops and immediately warn about turning the wheels or moving the stops, the second must conduct the tests and record measurements;

— the duration of the test should not be more than 5 s.

Carrying out the test and evaluating its results:

Be sure to secure the front and rear wheels.

If necessary, install a tachometer.

Apply the parking brake.

Press the brake pedal with your left foot and hold it in this position throughout the test.

Start the engine.

Set the driving mode selector lever to the “D” range.

While pressing the gas pedal with your right foot all the way, record the tachometer readings. Take a break for at least one minute.

Repeat the test by setting the Opel Astra J automatic transmission driving mode selector lever to the “R” range. When evaluating this test, you need to know that with each press on the gas pedal, the tachometer needle should smoothly rise and stop in the range of 2400-2700 rpm.

In this case, there should not be any extraneous noise, vibration or shock, and the car should remain in place.

If the tachometer readings:

- less than the nominal value, but the same in both ranges, then most often the reason is insufficient engine power;

- above the nominal value in both ranges, then most likely the reason lies in a malfunction of the torque converter or gearbox;

- higher than the nominal value in one of the ranges, then it is most likely that the fault is only in the automatic transmission.

The most difficult to conduct and evaluate is a road test, which is carried out to determine switching points, detect extraneous noise, vibration and slippage in automatic transmission gear shift Opel Astra J.

To ensure safety, the test should be carried out on a sufficiently wide, level and empty section of the road; Before leaving, you need to warm up the engine and gearbox thoroughly.

Carrying out a “road test” of the Opel Astra J automatic transmission and its evaluation

Set the driving mode selection lever to position “D” and, gradually pressing the gas pedal, check for the presence of gear shifts I-II, II-III, III-IV and IV-V.

If there is no switching, then the automatic transmission or control unit is faulty; If the switching points are too long, then the problem is most likely in the control system.

Fix the speed at 70 km/h in “D” mode and lightly press the gas pedal. Engine speed should not change suddenly. If the tachometer shows a sharp jump in engine speed, then it can be argued that the torque converter is faulty and will soon fail completely.

Stop and move the Opel Astra J automatic transmission mode selection lever into the manual gear shift range.

Gradually pressing the gas pedal, check for 1st shift. While driving in second gear, release the accelerator pedal and notice the presence of engine braking.

Opel Astra J

By repeating this operation several times, make sure that switching I II and II I is not accompanied by vibration, shock or slipping. If there are no negative phenomena, then the box is in good condition.

Stop completely and, by moving the lever to position “1” and smoothly pressing the gas pedal, make sure that there is no switching to the second stage, and also check for engine braking when releasing the gas pedal.

When you repeatedly press and release the gas pedal, listen to the operation of the 6T40 automatic transmission of the Opel Astra J to identify any extraneous noise and vibrations. If there is a switch to the second stage or there is no engine braking, then the control and monitoring unit is faulty.

Stop and, having switched to the “R” range, sharply press the gas pedal. After making sure that there is no slipping, vibration or extraneous noise, continue testing.

With the vehicle parked on a slope of about 5°, move the driving mode selector lever to the “P” position and release the brake. The car must be locked in place; if the car rolls, then the cause should be sought in a malfunction of the box parking mechanism.

We remind you that when performing the test you need to pay attention Special attention for the presence of extraneous noise and vibrations. They must be treated with due responsibility, since these noises and vibrations can be caused by unbalancing of the torque converter, drive shaft, etc., which can lead to damage to the unit.

Checking the level and topping up the working fluid in the automatic transmission of the Opel Astra J

Periodically (but at least after 15,000 km) check the fluid level in the Opel Astra J automatic transmission. The design of the gearbox does not provide for replacement of the fluid during the entire service life of the vehicle.

However, sometimes the need to replace the working fluid may arise, for example, if the quality of the working fluid in the gearbox deteriorates after it overheats, etc.

Replacing the working fluid in an automatic transmission requires certain skills, so to complete replacement working fluid, contact a specialized service.

For automatic transmission Opel Astra J, the manufacturer recommends working fluid GM 93740313 or DEXRON VI.

Start the engine and warm up the transmission. The temperature of the fluid in the box should be 70-80 "C. To speed up warming up, you can take a short drive in the car. Usually at a temperature environment 20 °C is enough to make a 10-minute trip in a quiet driving mode.

Place the car on a flat, horizontal surface. Apply the parking brake. With the engine idling, press the brake pedal and move the selector lever from position “P” to position “D”.

While holding down the brake pedal, let the car run for 1-2 minutes in the “D” position, then move the selector 3-4 seconds sequentially to each of the operating modes and set it to the “P” or “N” position. The engine must be running during the test.

It is unacceptable for even a small amount of mechanical impurities to get into the working fluid of the box, so before removing the liquid level indicator (dipstick), carefully wipe the surface around the meter tube free of dirt.

The fluid level should be between the upper and lower limits of the “HOT” scale on the dipstick.

If checking the level is forced to be carried out in a cold gearbox, use the scale on the dipstick.

The range between the marks is a guideline and should not be used to accurately determine the level of working fluid in the Opel Astra J automatic transmission. At the first opportunity, repeat the check in accordance with the recommendations.

If the fluid level is approaching or below the lower limit of the "HOT" scale, add fluid. Working fluid add small portions through the level meter tube. Add only the operating fluid recommended by the manufacturer.

After adding fluid, be sure to check the level again. The maximum permissible level must not be exceeded, as this may lead to failure of the 6T40 automatic transmission.

In 2010, GM, inspired by the idea of ​​downsizing, released its next engine. With a 1.4-liter volume, thanks to the turbine, there is no high pressure(about 0.5 bar) the power was 140 hp. This power unit in model Opel range known under the designation A14NET, and among Chevrolet models– under the symbol LUJ. The 120-horsepower versions of this engine are designated A14NEL and LUH, respectively.

The 1.4-liter GM turbo engine is widespread not only in Europe, but also in the CIS countries, as well as overseas – in the USA. Thanks to the “pass-through” displacement, cars with a 1.4 Turbo engine are gradually arriving in the states of the customs union. In this case, we are talking not only about compact Opel models, but also about Chevrolet Cruze and Buick Encore, purchased in the USA.

Engine problems 1.4Turbo (A14NET/LUJ). Crankcase ventilation

This engine as a whole does not deliver serious problems, but he has some congenital “sores” that were recognized by the manufacturer. During the warranty period, these problems were fixed free of charge, but most often they appeared after warranty period.

The crankcase ventilation system causes particular trouble. As with any turbo engine, to implement it, engineers had to resort to certain tricks. But practice has shown that the quality of implementation of these tricks is poor. In fact, 100% of A14NET / LUJ engines encountered problems with the crankcase ventilation system (CVV).

All three components of the VKG system fail:

• a diaphragm located directly in the plastic valve cover;
• check valve in the plastic intake manifold;
• corrugated hose running from the intake manifold to the turbine.

Usually problems occur with the first two nodes of the VKG system.

Signs of problems with the VKG system of the 1.4 Turbo engine (A14NET / LUJ) are:

• increased consumption oil (oil burns in the cylinders or in the exhaust manifold, leaking through the turbine cartridge or will go out through the seals and/or through the valve cover);
• smoky exhaust;
• hissing sound in engine compartment(sound of air being bleed);
• floating speed or engine tripping;
• reduction in engine power;
• increased fuel consumption;
• computer diagnostics will show the following errors: P0106, P0171, P0299, P0507, P1101, P2096 (they indicate a lean mixture or a difference in the calculated and actual air flow);
• indirect sign: the inability to unscrew the oil filler plug or after unscrewing it or removing the oil dipstick, the engine speed begins to fluctuate.

Due to the failure of one or another system component, the pressure in the crankcase and in the valve cover cavity will greatly increase under the influence of the air pressurized by the turbine. Problems with the VKG system cannot be ignored: improper mixture formation and detonation occur, oil is squeezed out and shaft seals wear out, the catalyst becomes clogged, and spark plugs fail. Due to high pressure in the crankcase, oil from the turbine cartridge stops flowing into it and is instead squeezed out into the turbine or compressor part.

What to do if the crankcase ventilation system is malfunctioning?

First, you need to make sure that the faults really concern the VCG system. To do this we do the following:

• open the hood and remove the decorative cover from the engine;
• on the driver’s side on the plastic valve cover we see a round casting (see photo below);
• the casting contains a rubber diaphragm-regulator of the VKG system;
• If it is destroyed/torn, then when the motor is running, air is sucked in through the hole, simultaneously making a whistling sound. This whistling stops if you plug this hole with your finger. In this case, the engine speed may begin to “float” and vibration will increase.

This casting contains a rubber diaphragm for the crankcase ventilation system. When the diaphragm is destroyed, air is sucked in through this hole (in some cases, crankcase gases are blown out from here).

Regardless of whether you are convinced that the diaphragm is working, you need to check one more element of the VKG system. The engine must be turned off. Then you need to find the place where the corrugated hose is connected to the plastic intake manifold. The hose must be disconnected by first removing the bracket that secures it.

At this point, crankcase gases enter the intake manifold and, along the hose, into the intake tract in front of the turbine. This ensures crankcase ventilation. The valves block the counterflow of gases from the intake tract (where, thanks to supercharging, the pressure is almost always high and vacuum, as in naturally aspirated engine, does not occur) back into the crankcase.

After disconnecting the hose, you need to look into the hole in the intake manifold. The “nipple” of the mushroom valve should be visible there. It is clearly visible by its bright orange or red color. In some cases, you may need a cotton swab, soaked in solvent: This can be used to feel and lightly clean the valve to confirm its presence. If the valve cannot be detected either visually or with a stick, then it simply does not exist. The fact is that the valve simply rips off its seat, after which it flies somewhere along the hose towards the turbine.

The mushroom valve of the VCG system must be present in the intake manifold.

The next step is to check the permeability of the entire hose and the functionality of the second valve located at the point where the hose is connected to the intake tract near the turbine. You need to blow into the hose - the air should flow freely. And then you need to “inhale” from the hose - while the air from it (i.e. in the opposite direction) should not pass. Often the hose simply cracks, causing air leaks. If none of this happens, the entire hose needs to be replaced.

To solve problems with the VKG system, you have to change the plastic valve cover (there are already offers for used valve covers with a restored diaphragm), a plastic intake manifold (since the check valve located in it is not supplied separately) and a hose with a second valve.

Problems with turbine 1.4Turbo (A14NET/LUJ)

The GM 1.4L turbo doesn't die on its own. Its service life may be greatly reduced due to the described problems with the crankcase ventilation system. Incipient lubrication problems and possible back pressure in the exhaust manifold negatively affect the operating conditions of the shaft support bearings.

The manufacturer recognized one specific problem with the turbine of the 1.4 Turbo engine (A14NET / LUJ). The problem is that the return spring of the actuator that controls the internal turbine bypass valve weakens over time and does not perform its function well. Because of this, more and more slips past the turbine wheel in medium and high load modes. exhaust gases designed to spin the turbine impeller. The engine response and its power generally decrease, and “error” P0299 (low turbine pressure) may be recorded.

The actuator, as intended by the manufacturer, cannot be replaced separately. However, there are already proposals for non-original actuators. But its installation must be entrusted to specialists, since it requires adjustment and a special approach to installing the actuator rod to the valve.

Destruction of engine pistons 1.4Turbo (A14NET/LUJ)

The saddest and fairly common problem of a small GM turbo engine is the destruction of its pistons, the partition between the compression rings.

The problem is known for cars operated in America and the CIS countries. Most often found on cars produced in 2010-2013. Pistons can be destroyed both after a mileage of 20,000 km and well beyond 100,000 km.

The manufacturer does not provide the exact reasons for the destruction of the pistons, but they are easy to determine:

• Piston destruction occurs due to detonation, which occurs when low-quality fuel is used. This reason also covers “chipped” engines, where, due to increased pressure in the combustion chambers, detonation can occur even when operating at fairly high speed. quality fuel;
• a malfunction of the crankcase ventilation system causing incorrect mixture formation (mixture too lean).

The destruction of the pistons of the 1.4 Turbo engine (A14NET / LUJ) occurs due to detonation that occurs when operating on low-quality low-octane fuel or with the wrong composition fuel-air mixtures.

Where to buy a contract 1.4 Turbo engine (A14NET / LUJ)?

Opel motor/ Chevrolet / GM 1.4 Turbo (A14NET / LUJ) can be purchased from the warehouse of the company Ravto.by, which has its own site in North America. In the USA, Ravto.by independently dismantles cars for spare parts and sends the parts to warehouses in Minsk and Moscow. For each part, and especially the engine, Ravto.by stores and transmits to the client information about the actual mileage traveled.

What is very important when purchasing an engine or automatic transmission is that the mileage on power units and transmissions from the USA is an order of magnitude less than on European ones. In addition, motors removed from American cars, differ in the minimum number of engine hours due to less stressful and traffic-free traffic. The Ravto.by site is located in the southern United States and disassembles cars from this warm and not densely populated region.

Not long ago on my . An unpleasant error appeared, or rather there were two of them: 84 and 89, and it was also burning hysterically ABS badge. I press on the gas, but the car doesn’t really move, it barely develops speed, the engine doesn’t want to spin at all above 2000 rpm. A LITTLE SHOCK! I immediately thought that if the ABS came on, it meant that it was the problem, I went to the forums, but the brake system had absolutely nothing to do with it! Errors appear on three cars - a Chevrolet Aveo, a Cruze, and an Opel Astra J - one concern "GM" - the engines are almost the same, and therefore the problems. I’ll say right away that I solved the problem, but I had to drive around and look for an intelligent diagnostician...

What made the situation more complicated was the fact that GM has now left Russia due to sanctions, so there are no officials left in our city (although there used to be two large ones). What to do? They write terrible things on the forums that this is mainly a problem with the throttle valve. And this is already creeping into big money! Guys, for a general understanding, I will use several photos that are not my own, but from open sources!

But first, about the mistakes.

Errorscode 84 and 89

ON the Chevrolet AVEO and CRUZ, they manifest themselves precisely - code 84 and 89 + lights up ABS .

But on the Opel Astra J it appears code 84 + it says that the engine power has been reduced + is on ESP .

Now a little decoding

84 – Engine power reduced.

89 – You need to undergo regular maintenance (vehicle maintenance)

The Astra may be slightly different, but the essence is the same; why the ABS and ESP sensors also light up is not very clear. Apparently the car shows with all its appearance that it is time for it to go to the service station. Reduced power means that it is turned on " emergency mode“, supposedly you just need to get to the service station and get it repaired, so you shouldn’t expect the car to be “quick.”

The car can either stall or start every once in a while, the speed fluctuates, or it won’t work for me.

What is the reason for the errors?

There are a lot of reasons, but it’s worth noting that they are not always critical, so you shouldn’t buy spare parts right away!

Guys, I want to warn you - before sounding the alarm, you must first look for an intelligent diagnostician and only then draw conclusions! After all, my problem was not at all with the throttle. But this became clear later.

Precisely a smart one with a good scanner, who understands your Chevrolet or Opel, because if you connect a cheap scanner like ELM 327, then it simply may not detect the error!

SO, what problems there may be, I’ll start with, perhaps, the most harmless one:

• Not enough coolant . Trite - YES? But for a couple of people, after replenishing the antifreeze, the errors went away. I attribute this to the fact that the coolant pipes pass through the throttle; it can be seen that if air begins to appear there, this causes an error. I did the same, my level was really low, but it didn’t help me!

• Throttle valve contamination . Due to high mileage or “crappy” fuel, after a certain mileage the throttle actually becomes clogged. The position of the damper differs from the normal one (different angle), the ECU sees this and is visible, which is why errors 84 and 89 occur. Just clean the damper and everything can be restored! But again it didn’t help me!

• The heavy artillery begins . This can be said to be a flaw of GM. The whole point is that throttle valve like many modern cars– electronic. If you remove it (and this is quite an undertaking) - remove the side cover (of the control unit), you can see 4 tracks and 4 contacts that run along them. It turns out that contact 4, which is closer to the center, breaks or, as many people write, simply gets erased (although this can manifest itself both with a mileage of 5,000 and 100,000 km, the flaw is still visible). This contact seems to “float” above the track, that is, it does not come into contact with it, and this is where this error appears! The solution here is to carefully, preferably with tweezers, bend the contact onto the track so that a connection occurs, in 80% of cases this helps and 84 - 89 go away. However, for some it didn’t help and they have to order a new throttle. The fact is that the contact is, as it were, complex, it does not consist of 1 metal element, but, as it were, of many metal “hairs”. As I understand it, if not everyone is pressed onto the track, then the error will not go away. But it’s really difficult to do this; it’s almost a piece of work. Therefore, my diagnostician told me that I can try, but this is really not a panacea, anyway, after a certain period of time, it will need to be changed. I want to say right away that the cost is considerable; the Chevrolet Aveo has an original throttle assembly starting from 13,800 rubles. For Chevrolet Cruze and Opel Astra J, prices can range from 15,000 to 21,000 rubles! Not a lot! But I got carried away, it’s not the throttle!

• Gas pedal. Almost the same situation as with the throttle. Only cheaper. The gas pedal also has the same block and 4 tracks with 4 contacts. As you probably understood, contact 4 breaks, only at the pedal. Again, you can bend it and restore it, but you can also replace it immediately with a new pedal. Fortunately, the cost for a Chevrolet Aveo - Cruz is about 3,000 rubles for the original. But the Opel Astra is about 4000 - 5000 rubles. But again, this reason is not mine.

Probably intrigued. To be honest, the diagnostician struggled with the car for almost a day. But I found a problem.

Cheap solution, my problem

I didn’t specifically combine them with the first four; I want to dwell on my problem in more detail. One more warning - before you get into your brains and electronics, let’s remove the battery terminals!

In general, my diagnostician was “from God,” as they say in Chevrolet and Opel, “he ate the dog,” he even worked for the officials for a year, but then he was laid off (GM left Russia). He has a professional scanner, costing 160,000 “our wooden ones”, and he updates the firmware on it every year (about another $300 - $400) - the balalaika is not cheap. Here is a photo.

But as he says, all the latest changes and information on new car models appear immediately (not only GM, all cars from our TAZOVs to Infinity). Not one ELM 327 (from China) has such information, and certainly not! Who will “cover” the annual firmware? That's why many Chinese scanners have errors - CAN'T READ!

Diagnostics - he connected his “miracle device” and it revealed that it was not a choke! Wow, a stone just fell from my soul, it revealed that it was a pedal! To hell with it, I’ll buy a new one for only 3,000 rubles, and replace it myself in a couple of minutes, unscrew one bolt, remove it and connect the cable.

However, the diagnostician told me - let's try to restore this one, if the error goes away then the pedal will be 100%, and then you will decide whether to buy a new one or drive on this one for a while. Okay, I agreed. But first he says - I’ll measure all the circuits - with a multimeter, I didn’t delve further, but it turned out that the pedal does not give any breaks! Unclear! It turns out she's whole?!

He tells me this - he recently came to see me in an Astra, code 84 + ESP was also on, in the end the contact on the ECU oxidized, they cleaned it, and everything worked like clockwork. Let's take a look at you. The 6 Volt load comes from there.

As a result, they oxidized to “green oxide”, in my opinion, from 42 to 46 contacts. When they took it all apart, it was a pity that there were no photos left. They cleaned it, put it back in place, and lo and behold, code 84 - 89 disappeared, the ABS went out, the car began to breathe deeply! Damn, there’s cold and heat and condensation under the hood in the fall. Looks like they got eaten up.

In the end, I didn't have to buy anything! The cost of repairs + diagnostics is 1500 rubles - SATISFIED AS AN ELEPHANT! The master noticed that the voltage at the ECU contacts is only about 3 - 5 Volts (there are a lot of them), therefore - YOU SHOULD NOT APPLY ANY LIQUIDS TO IMPROVE CONTACTS, such as terminal protection, etc. This way you can sag the voltage and simply burn out the ECU! Just needs cleaning, preferably not damaging protective covering contact (wipe with alcohol - carefully), then blow everything with compressed air.

OPEL ASTRA engine - power units made in Germany. Astra is considered one of the most common cars of our time among the middle class of the population. Simplicity of design, reliability and cheap maintenance have made the engines a favorite for many car enthusiasts.

Technical characteristics and volume

Opel Astra cars - vehicles golf class, developed by General Motors. The Astra platform is similar to many other Opel cars, namely Opel Zafira, Chevrolet Cruze, etc. Astra, at one time replaced the outdated Kadett.

Opel Astra has a significant number power units that will appeal to any car enthusiast. The company produces engines with a volume of 1.4 to 2.2 liters.

The brand's main competitor is Volkswagen Golf. Competitors also include: Ford Focus, Skoda Octavia, Toyota Corolla,VW Jetta, Renault Megane, Honda Civic, Mitsubishi Lancer.

Let's look at the main technical characteristics of some Opel Astra J engines:

Opel Astra J. Engine interruptions

During interruptions, the engine idles unstably, does not develop sufficient power, and consumes gasoline more. In addition, exhaust gas converters may fail. Interruptions are usually explained by a malfunction of the injectors or electric fuel pump (see. Engine management system), faulty spark plug of one of the cylinders, air leaks into one of the cylinders. It is necessary to find the fault and, if possible, eliminate it.

1. Start the engine and let it idle. Go to the exhaust pipe and listen to the sound of the exhaust. You can bring your hand to the cut exhaust pipe- this makes interruptions feel better. The sound should be even, “soft”, of the same tone. Popping noises from the exhaust pipe at regular intervals indicate that one cylinder is not working due to a failed spark plug, lack of spark, injector failure, strong air leaks into one cylinder or a significant decrease in compression in it. Popping noises at irregular intervals occur due to contamination of the nozzle nozzles, heavy wear or dirty spark plugs. If popping noises occur at irregular intervals, you can try to replace the entire set of spark plugs yourself, regardless of mileage and appearance, but it is better to do this after contacting a car service center to diagnose and repair the engine control system.

2. If the popping sounds are irregular, stop the engine and open the hood. Check that the wiring harness connector is securely connected to the ignition module...

3. ...and tighten the two screws securing the module.

4. If the wiring harness connector is securely connected and the module mounting screws are tight, remove the module (see Fig. Removing and installing the ignition module).

5. Remove the spark plugs (see Replacement and maintenance of spark plugs), carefully inspect the candles and compare their appearance with the photographs given in the next subsection Diagnostics of the engine condition by the appearance of the spark plugs. If the candle is black and wet, you can throw it away.

6. If all the spark plugs look serviceable, install them in the tips of the ignition module, and screw spare spark plugs into the spark plug holes of the cylinder head.

7. Connect the wiring harness block to the ignition module.

8. Connect the spark plug bodies one by one, for example, with a wire for starting the engine from an external current source to the vehicle ground (for example, to a wire connected to the negative terminal of the battery). Have a helper turn the starter crankshaft engine.

WARNINGS

Reliable contact of the spark plug body with ground is mandatory, since if an additional spark gap appears, larger than the gap between the spark plug electrodes, damage to the engine control system unit or high voltage circuit ignition module.

Carry out this check for no more than five seconds, so that during the subsequent start-up you do not damage the exhaust gas converter with unburnt gasoline that gets into it in the engine cylinders.
