Summer filter on a diesel engine where is located. Safety filter on the diesel: what it is

In this article, let's talk about what a diesel filter is. And what to do if he clogged.

Caring for ecology that actively unfolded in the past few decades has become a real challenge for automotive engineers.

Every year emissions harmful substances tightened, which means that you need to invent new ways to clean exhaust gases.

Consider the diesel filter, what it is, can it be without it and what to do if he came into disrepair.

The first serial attempts to install the particulate filter on dieselle are among the early 2000s, and already a decade later, in 2011, these devices have become mandatory for all cars with a motor on diesel.

Thank you for the appearance of the particulate filter included in, the ecological standards of Euro 4 and Euro 5 are needed.

The function that this filter performs is clear from its name and without unnecessary explanations - it should remove the smallest particles of soot from the exhaust gases resulting from incomplete combustion diesel fuel.

The filter is located as close as possible to the exhaust collector, where the gases temperature is still quite high, which helps to survive harmful substances right in it.

Sometimes the diesel filter is constructively combined with a catalytic neutralizer.

The construction of our today's hero is quite simple. Inside the device there is a special matrix made of silicon carbide and having a cellular structure.

This structure allows you to delay small particles. In addition, there are also various sensors related to the engine control unit.

They signal the computer at the right time that the filter has already been hammered and it is time to take measures to clean or so-called regeneration.

With the second problems, the regeneration, as a rule, occurs in an automatic mode, but in the stems cars with simpler and more cheap nodes can wait for the washing filter performed by specialists to a hundred.

Than older filterThe more often it requires one of these procedures, and sooner or later the question arises about his replacement. And here the owners of diesel cars, which can boast of compliance with the norms of Euro 4 and Euro 5, is waiting for an unpleasant surprise, and about it further ...

Replace or delete?

What is so unpleasant, the replacement of the particulate filter? The main problem of this procedure is the impressive price of the new node, which sometimes achieves 1000 euros and more.

Replace

It is clear to spend such money on a device that, in fact, is a whim of ecologists, not many car owners want. What to do? Is it possible to remove the scene filter at all?

Yes, it is possible to do it, but you need to remember:

When removing this device, the car will begin to correspond only to the norms of Euro 3.

In our country, this fact is permissible, but if you suddenly want to travel on your car to Europe, then there, when checking, you may be forced to immediately proceed to the local car service to install the filter.

Delete!

As the removal of the particulate filter occurs, because in reality, this process also has its own nuances.

Just dismantle it from exhaust systemUnfortunately, it will not work. The fact is that it is programmatically tied to a car's computer, and the system, finding the absence of this device, may even block the operation of the engine.

Therefore, the craftsmen came up with several options for how to remove the diesel particulate filter without any problems. Methods are:

• modernization of the electronic engine control unit, with the help of a special programmer in Brains, an updated version of the software is poured, in which there is no filter as such. The problem of the method is that the implementation of the machine in the program can entail the most unpredictable consequences, so deciding to carry out this procedure, find out from other car owners with the same car on the quality of work in a hundred years;
• installing the scenery of the scene filter - in fact, in this case a new small block appears in the machine, connected to its electronics and imitating all filter signals. This option is more preferable than the previous one, since no destructive interventions in the power electronics occurs.

The question is quite logical: the removal of the particulate filter is the effect on the diesel engine from this procedure? You will get about the following:

• due to the reduction of obstacles in the exhaust system for gases, the engine power will rise slightly;
• savings on the maintenance of the exhaust system;
• lack of boring errors in the onboard computer from the filter.

So, dear colleagues, we looked at the nuances that give the particulate filter on the diesel.

To new publications and meetings on the blog pages!

Such a device as a diesel filter is available in all diesel cars manufactured since 2011 (as well as on a number of models released after 2000 - then it has not yet been a mandatory element, but has already been used by some car manufacturers) in the territories of countries belonging to WTO (standard "Euro-5" adopted by the Customs Union).

The main task of such an element is to maximize exhaust gases from impurities harmful to the environment.

The use of particulate filters made it possible to reduce the content of soot particles in the exhaust of diesel cars almost 100% - if more precisely, by 99.9%.

What is needed and how the car filter is working

Currently, two types of soot cleaners are used in cars:

SAILE filter DPF. (Abbreviation from the words Diesel Particulate Filte) for diesel car Causes particles of soot with a size of up to 1 μm, which are formed as a result of fuel combustion. Such a filter is characterized by the simplicity of the device, but it requires regular cleaning actions (regeneration).

FAP type filter (Filtre a Particules Reduction) is a more complex device that does not require regular intervention. Regeneration (cleansing) occurs here in automatic mode.

The location of the particulate filter (see Fig. 1) - in the system of output of exhaust gases, behind a catalytic neutralizer. In some cases, it can also be combined with a neutralizer, and then its location is right behind the exhaust manifold.

This is a place where the exhaust gases have the highest temperature. In this embodiment, the device is called a "sabotic coating" filter.

The average resource of the particulate filters is designed for 150 thousand miles. But this is a European standard. On Russian fuel, according to the reviews of owners and workers of car service, this indicator is reduced almost three times.

At the moment when the on-board computer is issued an error saying that the scene filter clogged, the car owner will need to take one of the following solutions:

1. Full replacement of the particulate filter. Very expensive event. Of course, the price is very dependent on the brand and the model of the car, but in any case, this action is much more expensive than all items below. For example, on BMW, the replacement of the particulate filter will cost approximately 1500 euros.
2. Physical removal of the diesel filter. The procedure is also not cheap, and has a number of shortcomings. It is not enough to just take and cut the filter by replacing the pipe area. On the data coming from the sensors of the Symbhal filters, a number of procedures are tied on-board computer, which means that it will be necessary to replace its firmware. Replacing the firmware does not always happen smoothly, in some cases errors occur (false indication responses, other problems with an on-board computer).
3. Cheating sensor size filter. Lies in the installation of a separate device that emulates the normal operation of the sensors (forging signals) or software deletion Squeezing filter from the electronic control unit system. This procedure does not exempt the owner of the car from cleaning the filter itself. However, it significantly prolongs the life of its work or allows you to silently remove the particle filter with the smallest errors in the operation of the onboard computer.
4. Regeneration. The most correct procedure, because the removal of the filter increases emissions of harmful substances into the atmosphere, despite the fact that even without this element, European cars successfully pass technical inspection According to Russian standards. In this case, the cost of filter regeneration remains acceptable in comparison with the same removal or replacement, although they require periodic repeat.

Regeneration Types - Cleaning Methods

In essence, the diesel filter is a container filled with a substance with a porous structure (the ceramics is most often used). When passing exhaust gases through these "honeycombs" of soot and Gare settle on the pores of the filler.

Over time, the passage of exhaust gases is cleaned and the passage of exhaust gases is difficult, which leads to an increase in fuel consumption and reduce engine power, risk risk of various problems.

To restore the filter properties, the regeneration procedure is performed, which can be two types:

1. Active. Pore \u200b\u200bcleansing is due to an increase in temperature inside the filter to 600-1000 degrees Celsius. At such a temperature of the soot completely burns.
2. Passive. Here, the removal of soot occurs also due to its combustion, but the combustion occurs at a temperature of about 350 ° C (this is the normal temperature of the exhaust gases of diesel). For soot oxidation, a special catalyst is needed, lowering the reaction temperature - for example, platinum in filters volkswagen. (The largest catalytic coating filters that were previously mentioned).

Active regeneration requires the fulfillment of special procedures from the car owner, and passive occurs without any participation of the driver's driver.

If regeneration does not have the desired effect, you can always just wash the filter. Flushing of the particulate filter Performed after removing it from the car. The unit is placed in a special chemical composition for a while, and then skip the same composition through a pressure filter.

How to start the regeneration of the scene filter

Increase the temperature inside the sump filter for complete combustion of soot can be one of the following methods (active regeneration):

1. Introduction to fuel mixture Special additives (most often based on cerium), which when passing, along with exhaust gases continue to burn. In this case, the removal of the node of the car is not required. The disadvantage of this method is its low efficiency - the method can give a positive effect only at the initial stage of pollution (no more than 2000 - 3000 kilometers from the moment of the error indicator on the on-board computer panel).
2. Run a special engine operation procedure through an automotive electronic control unit. In this case, the air supply is reduced, the fuel is injected on the release tact (that is, it falls into the exhaust gases unborn in the system). In certain models of cars, original technologies are used, for example, a additive is additionally introduced, or the outflow of burnt gases is reduced, etc.

If regeneration does not help - need repair of scented filter.

It will be removed, will figure it out and refund manually or completely replace in the workshop. Of course, it can be done with your own hands, but it is better to trust specialists.

The regeneration procedure is started most often without user participation:

1. The soot rate increase sensor in the filter is triggered.
2. In the process of movement, the control unit will independently increase the revolutions, reduce the air flow and clears the particulate filter.

But if the attempts of cleaning are not crowned with success, or the level of soot will be critical, the control unit will refuse to clean the attempts and will highlight the error.

In this case, you can try to start the procedure yourself through the control menu of the electronic control unit (EFP) and follow the instructions of the system (if the automatic speed control mode is not supported).

It all depends on the model of the car and the firmware of the EPP. In some cases, it may be necessary to know the knowledge of service codes or connecting external diagnostic devices.

What fluid will help for the regeneration of the diesel auto filter

If you have not become the owner of a car with a sabotic coating filter or built-in automatic regeneration procedure, you can always resort to the use of special services.

You can try to restore the particulate filter, for example, using universal funds:

1. Regeneration catalysts from ARDINA - Diesel Particulate Filter Regeneration AID (poured into a tank with fuel as a additive).
2. Liqui Moly Pro-Line Diesel PartikelFilter Reiniger is a cleaner that requires forced injection, after use it must be neutralized with another solution (Pro-Line Diesel PartikelFilter Spulung).
3. Liqui Moly Diesel PartikelFilter Schutz is another additive that serves as a catalyst.

Video Description

If the car uses the original additive (for automatic feeding from a special tank in the regeneration mode of the particulate filter), then it is necessary to order it from official dealers.

In Europe, they are considered one of the most popular. BUT B. diesel engine, as in gasoline, fuel does not burn completely. As a result, various poisonous and additions are also formed in the exhaust gases, there are also soot in them, because the hydrocarbons are not completely burned. In Europe in 2000, the fighters for the environment developed a standard for harmful emissions in environment. Automakers, in order for their products to be suitable for these standards, the particulate filter on the diesel should be installed. What it works and how it works, you need to know those who drive on diesels. Today we will try to answer all these questions.

Main functions

In order to better understand the purpose of these devices, it is necessary to touch the topic of exhaust gases. The automotive exhaust contains a mass of particularly toxic and carcinogenic substances.

Thus, carbon monoxide, unburned hydrocarbons, aldehydes, sulfur oxides, tetraethylsvinets have a very harmful effect on the environment. In addition, the exhaust gases diesel carIn particular, heavy trucks, large quantities contain soot.

In order to reduce the concentration of this component, in the design modern carmobile An oil filter was introduced on the diesel. What is this detail? This is something similar to the catalyst in the gasoline engine.

What does item look like

So, this device is intended to neutralize the soot - the product formed during the combustion process of diesel fuel. There are two species - this is closed (DPF) and closed with the possibility of regeneration (FAP).

With all its simplicity, in fact, these auto parts for foreign cars have a rather complex device. Regardless of performance, the filter is a metal cylinder. It contains nozzles - input and output. The output is connected to the exhaust gas purification system.

The main element of the filter is a special matrix, which is made of silicon carbide.

It is concluded in a metal cylinder. The structure of this matrix is \u200b\u200bcelly. As for the cross section of the cells, it is often square. But more efficient cells having an octagonal form.

In addition, a diesel filter has several sensors in the design. This is a sensor that captures the pressure difference, and the sensor of the input and output temperature.

Principle of operation

The size of one soot particle is approximately 0.05 μm. By chemical composition, this product is nothing but ordinary carbon. To delay these particles using conventional tools is very difficult due to the size of the element. To capture South, it is necessary to use the diffusion principle. To understand what is a typical particulate filter on a diesel engine, which is the device, it is necessary to look inside it.

So, the filter inside is a ceramic matrix. This is a whole series of tubes, while the ends are closed. Inside this matrix, the exhaust gases come from the motor side, however, when the gases fall into the tubes, they simply cannot move on to move. Then through the walls of the tubes, they fall into the adjacent open cavities and can then get out of the matrix. In the process of diffusion, even the smallest particles remain inside the filter, which means it performs its task.

Where is the diesel filter

Find this item will not be difficult. The filter is often installed in exhaust system car.

Due to the design features, the part can be found between the silencer and the catalyst. In some cases, the device can be combined with the catalyst and is located directly at the exhaust manifold. There is a maximum temperature of gases, and such a filter has a catalytic coating.

Receptions

To effectively use on a diesel engine, the price of which is quite high (about 900 euros), it is necessary to properly operate the car. The thing is that in the process of cleaning the exhaust gases, the cells and tubes are clogged with soot. This leads to a decrease in the efficiency of the diesel engine.

The filter bandwidth decreases and the resistance to the exhaust of waste gases increases. Many manufacturers in order to increase the service life of this stock without need frequent replacementThe special filter operation algorithm was applied when the fill level is controlled. If the filter is filled in so that the engine power is lost, the filter regeneration is started.

Causes of reducing efficiency

There are several reasons why filters are clogged. The main reason is the quality when the car is refueling by poor-quality fuel, a large amount of soot is formed - the filter is quickly clogged, which reduces its service life.

Another reason is insufficient temperature. So, the soot burns not completely.

The thing is that it is a diesel particulate filter. What is it? It not only delays particles, but also maintains the temperature for burning them. However, it should be said that this happens when the heating of the spent gases is high and is no less than 600 degrees Celsius. With smaller indicators, the soot will not burn.

Among the reasons for reducing the temperature of the gases also allocate several. These are motion modes, traffic jams, violation of the combustion process of fuel. Thus, the temperature in the system will not rise if the speed is low, and the movement is accompanied by frequent stops.

Monitoring status

In order to control the status of the Diesel engine path is equipped with control and measuring equipment. It includes temperature and pressure sensors. These elements form signals for the electronic control unit, and it determines whether the filter is filled or not yet. When the element is strongly filled, the cleaning process begins.

How to clean

In order to restore the efficiency of the engine when filled with a sump filter, it is enough to use several simple methodsthat will help run self-cleaning. Regeneration can be both passive and active type.

In any case, the process occurs through the combustion of the soot and the release of tubes and channels.

For the regeneration process, it can be used to increase the level of heating of exhaust gases, additives, or washing the sump filter. Additives will help reduce the temperature at which the soot will burn. A flushing with special substances will help clean the filter.

Passive regeneration method

Such cleaning can be carried out directly by car enthusiast. The need for regeneration will report the corresponding indicator. Also run this process is necessary if the dynamics or power of the engine decreases.

The most important thing is to increase the temperature for spent gases. This is done by movement by car with full load. It is enough to drive 30-40 km so that the filter is completely cleaned and the whole soot burned out. The second option is to use special fuel additives.

Active regeneration

This mode can be run by automatically controller. For this, the electronics analyzes information from the temperature sensor and pressure sensor. He informs the electronic unit The control that the filter is scored, and the sensor reports the temperature. If it is not enough so that the soot is completely burned, the ECU may additionally inject fuel in the process of producing exhaust gases. This will burn soot in the exhaust. It also allows you to raise the temperature to the desired level.

If there are other equipment in the graduation path, which also increases the heating, the ECU can also use them.

Flushing

For this procedure, special fluids are needed.

The procedure itself as a whole depends only on the type of means.

So, the filter is removed and closed its holes. Then the cleaning fluid is then poured in such a way as to fill the entire filter volume. Next, the product must be left alone for ten o'clock, while to shake the filter from time to time. After that, the part is washed with warm water and installed back to the car. There are several types of liquids, and for each - your flushing method. It should be remembered before performing these procedures.

Flushing and cleaning will help extend the operation of the element, because the replacement of the scene filter is a very good pleasure.

But sooner or later, the term will come after all. It is recommended to change filters after 180 thousand kilometers.

The depreciation of this design affects primarily the conditions of movement, the quality of fuel, as well as the driving style. If the machine is experiencing significant loads, the replacement of this item may be required earlier.

So, we found out why this detail is served in the car. The particulate filter, like the other auto parts for foreign cars, is an important detail of a modern car. This element improves the environmental situation in the world, and this is the health of people. High-quality ecology is a healthy society and happy children.

Compliance with the norms of environmental friendliness often turns into vehicle owners with additional problems due to the complexity of the design separate nodes and machine units. In particular, the sage filters installed on modern diesel engines are clogged and quickly come into disrepair, which is why certain failures appear in the operation of the machine. What to do in this case? There are two outputs: either remove the diesel filter, or clean, but for some reason many motorists choose the first option.

Why remove the diesel filter

Highly contaminated diesel fatter adversely affects the performance of the entire car, and which owner will like that his car has decreased, the fuel consumption increased markedly, and the annoying light bulbs are constantly lighted. Of course, you can resolve the question of the substitute part, but it will be necessary to pay a fairly decent amount for it. In such a situation, the only reasonable way out, at least from the point of view of many motorists, is the complete removal of the particulate filter from the car, that's just not everyone is thinking about possible consequences.

According to experts, the view is that the extraction of this detail favorably affects "well-being" iron horse - No more than a myth, because even despite temporary improvements in the speakers, problems will still have problems.

Methods for removing the size filter

You can remove the sump filter from your car in two ways: Through the physical removal of all components, the part or by software deactivation, which is a more competent approach to the question.

In the first case, you need to get to the placement of DPF and with the help of a grinder cut a block with the filter element itself and catalyst. After that, a special flamesteller is installed on their place or a conventional piece of pipe is welded. The installation of the plane sensor allows to increase the durability of the exhaust system, in particular, and the muffler. Moreover, due to this device, the power of the motor is significantly increasing, and the sound of the exhaust becomes much quieter.

The software removal of the particulate filter on the diesel is considered a more humane method of dismantling the part. It is used when they want to avoid errors in the operation of the engine ECU, which is achieved by adding an exhaust temperature measurement sensor and lambda-probe temperature into a piece of welded metal pipe. Also, after removal of the sump filter, you will have to perform a car tuning chip, which eliminates the combustion products of black.

After performing the specified procedure, you will notice a decrease in the "capriciousness" of the motor in terms of service, although the warranty from the manufacturer will have to forget. DPF Removal Procedure at Station maintenance It will cost approximately 25-30 thousand rubles, but it all depends on the complexity of the work and the location of the element itself.

What will happen if you remove the filter

Duck scored filter with your vehicleYou, of course, solve the problem with power and fuel consumption, but at the same time some other inaccuracies will appear in the car. Outsided sounds With running force aggregate And the incorrect display of the status of the part is just a few of them. The system will see that the particulate filter is not clogged, and such just can not be, then decides that he is simply faulty, and translates the car into the "emergency" mode. To avoid all these nuances, you should reprogram (or, as the people they say, "reflash") the control unit, otherwise the ECU will constantly give out the fault codes. There are two main options as you can do it.

In the first case, take the "firmware" of the versions of the vehicle to which the diesel filter is not installed, and load it into your control unit. However, no one can know exactly what is not yet in this firmware, and what consequences of the removal of the particulate filter here "get out". It is likely that staten parameters The car will not be able to "get along" with new changes, as a result of which it can stop working or any other function that was not in the old program.

You can download the desired firmware on the Internet, but in this case it is impossible to predict the result at all. If such a firmware also works for a while, then no one can guarantee her good operation a year later. Floating speeds, forever shaking speedometer arrow and uneven injection - Not everyone possible consequences Use of low-quality software.

Most the best way Solutions of problems with software is the installation of programs that the manufacturer uses, but supplemented by some changes made by an experienced programmer. Such software is loaded into the control chip via a special programmer.

Did you know? The particulate filter is the development of Peugeot Concern's specialists who installed the first in history of the particulate filter on their car 607 model Row 2000th year.

There is another way to avoid problems associated with the removal of the sump filter. You need to install an emulator that would imitate the availability of a new particulate filter machine. That electronic device Sends signals identical to a real filter signals thus deceiving on-board computer.

Advantages and disadvantages of filter removal

Why remove the diesel filter, you have already learned, but you should always consider not only the advantages, but also the disadvantages of any action performed. To the positive moments of seizure of the particulate filter include:

an increase in the power and thrust of the engine (it is possible to achieve due to the reduction of resistance in the exhaust pipe);

Lack of need for expensive maintenance and filter cleaning;

Savings of motor resources due to the lack of regeneration processes;

Lack of pop-up errors that are associated with the work of the particulate filter.

As for the shortcomings, they are not so much. The main - the car ceases to comply with the standards standards of Euro-4 / Euro-5, which means that the inspection machine will no longer pass, at least without additional material spending. True, if you look at the problem on the other side, this nuance will not be so significant, especially in comparison with the value of the procedure for replacing the part. Do not forget about the above described technical problemsassociated with the absence of a smbed filter that appear as a result of its removal from the vehicle.

What is a diesel filter and why you need you can read in one of our articles - link

On this page, we will try to describe the main symptoms that indicate a malfunction of the diesel vehicle diesel filter system (the manufacturer is not important - consider the general problems inherent in all cars with Euro-4 and higher standards). After all, exploiting a modern diesel car in our modern conditions, especially within the city, the sage filters often fail under the range of Kolo 70-90 thousand km, and the problems with them sometimes begin earlier, already at 40-60 km. Run.

Why the particulate filter fails so quickly:

Here it is just worth remembering the device of the filter itself and its principle of operation. The filter is always installed for the exhaust manifold, in the immediate vicinity of the engine and exhaust gases pass through the filter before entering the rest of the exhaust system and further into the atmosphere. The main filtering element of the particulate filter is a ceramic matrix, usually made from silicon carbide. It has a cellular mesh structure inside and porous channel walls that perform the role of filters and detains particles of soot from the engine exhaust gases. Over time, the filter begins to be clogged with soot, but the system provides the possibility of cleansing the particulate filter (called regeneration). This feature is controlled using an engine ECU, which polls a number of sensors (pressure drop sensors before and after the sump and filter and temperature sensors) And based on their testimony, the ECU includes regeneration.

I would like to see that poor-quality fuel also strongly affects the resource. squeeze filter And the engine as a whole. The amount of soot directly depends on the sulfur content in the fuel, and when its overestimated parameters, the filter is clogged faster. worsen.

Regeneration is two types - passive and active.

Passive regeneration is more efficient and is usually occurring when traveling more than half an hour in the rustic cycle during engine revolutions about 2500 rub / min. When passive regeneration of soot in the filter, the catalyst account is oxidized and high temperatures Exhaust gases (the passive regeneration of soot occurs only when the constant temperature is reached 350-550 ° C). Such regeneration is more effective and if the car is operated in country conditions - it is undoubted that the diesel filter will serve much longer.

In the conditions of the city and dense traffic, heat the diesel filter to such a temperature with normal ride is almost impossible, so when the filter is stuck, the ECU uses active regeneration, injected the diesel engine to the engine in excess (while from the exhaust pipe on idling It goes smoke white and turns can be slightly overpriced), which would heat up the sump filter to a temperature of 600-650 ° C. Upon reaching this temperature, the soot particles in the filter react with oxygen and as a result, harmless carbon dioxide is formed. But such regeneration is less effective, so often the "urban" diesel car already has problems with a filter on very small runs. In addition, the car may not include regeneration with a number of reasons - an active error in the computer, incorrectly closed tank cover, malfunction of the EPR, etc.) and then the sump filter will come to the unsuitable state very soon and the ECU, based on sensor readings. Exterminating the limit the filter slaughter will write a constant unstained error and the car will only move in emergency mode (up to 3000 per. without inclusion of the turbocharger). In this case, the filter is replaced with a new or Software removal of the diesel filter And his physical removal.

Of course, you should not forget about the quality of fuel, often sold at the gas station in our country, especially diesel, because the quality of diesel fuel is a very important factor for all modern diesel engines high pressure from direct injection Fuel.

Main cons operating a vehicle with faulty summer filter:

power loss

increase the fuel consumption

as a result of a strong filter charge, the exhaust gas recirculation system (EGR) is much faster "Clear", which leads to the failure of the expensive valve, and in some cases the turbocharger

the engine works in emergency mode "to wear", the turbocharger does not turn on and turns up to 3000 rpm. - In the investigation of this automatic transmission receives an insufficient torque from the engine and manages packages with high load (shocks when switching)

if the filter bundle is close to critical, and the car continues to be operated, then possible failure of the engine

Symptoms talking about possible malfunction the sump filter of his stuffiness and necessity removal of the diesel filter :

The emergence of increased flow and fuel consumption, frequent regeneration ( white smoke When parking at idle turns testifies to the passing active regeneration)

Reduced power and motor thrust

N. establish engine work and increased smoke when working

Sh cocking sound when operating the engine

Per level left motor oil in engine(subject to the norm)

Engine transition in emergency mode(up to 3000 rpm without the normal operation of the turbocharger).

Indication on dashboard:

part of the car on the instrument panel is present Syptizer indicator- Usually it lights up or starts blinking when malfunction, sometimes the check-eng indicator flashes.

All the signs indicated here are not one hundred percentage of the defect of the particulate filter system and for the full identification of the problem before you begin to any interference in the car, you need to make a qualified car diagnostics. After identifying the problem by a specialist, you will understand whether it is necessary to change or remove the diesel filter .
