HI All,Found this this great article that should help explain the whole DPF life story, with common problems you may experience. Maybe worthy of a sticky VAG DISESEL PARTICULATE FILTERSCourtesy of David Bodily Volkswagen Technical Support Specialist. Diesel Particulate Filter DPFDetailed below is important information outlining the function and features of the Diesel Particulate filter which all members of your team need to be aware of. Diesel particulate filters are becoming more commonplace on diesel engines, particularly sizes 2. L upwards. This is in order to reduce the exhaust emissions as required by European legislation. The prime reason for a DPF is to reduce particulate matter entering the atmosphere. Particulate matter is found in the form of soot, which is produced during diesel combustion. The DPF traps most of the soot which would normally travel down the exhaust and into the atmosphere. The DPF can hold a certain amount of soot, but not a huge quantity and therefore it needs to go through a process called regeneration in order to clear the soot loading.

The particulate filter warning light has just come on on my 2. 2hdi 406, accompanied by a nice message telling me Diesel antipollution system. The Custom Special File for Each Vehicle. We understand every car is unique and special. That is why we using special software. When the soot goes through a regeneration process it will be converted to a much smaller amount of ash. The ash is non removable. There are two types of regeneration, passive and active. During long motorway journeys, passive regeneration will occur. This needs no intervention from the engine control unit. Due to the raised exhaust temperatures on a long journey temperatures between 3. C, the procedure occurs slowly and continuously across the catalytic coated with platinum DPF. The catalytic coated DPF is situated close to the Engine, therefore the exhaust gas temperature is high enough 5. C to ignite the soot particles. Due to this soot is burned off and is converted into a smaller amount of ash. UKs Leading Nissan DPF Removal Specialists. See Our Nissan Navara DPF Removal with a Lifetime Warranty, No Smoke, No Limp Mode No WorriesActive regeneration is when the ECU intervenes when the soot loading in the DPF is calculated to be 4. The procedure lasts for about 5 1. Specific measures are taken by the ECU to raise the engine exhaust temperature to above 6. C, these include switching off the exhaust gas recirculation and increasing the fuel injection period to include a small injection after the main injection. The soot particles are oxidised at this temperature. The ECU will trigger a regeneration process, if for some reason this is aborted, ie. This will continue for 1. If after 2 attempts of 1. At 5. 0 soot loading, the ECU will continue to maintain maximum exhaust temperatures of 6. C to 6. 50C to cause a regeneration process. The system will try to run a regeneration process for 1. If unsuccessful, the system will repeat this process for a further 1. DPF light on the driver display panel will then be lit. The owners handbook states, the DPF symbol lights up to indicate that the diesel particulate filter has become obstructed with soot due to frequent short trips. When the warning lamp comes on, the driver should drive at a constant speed of at least 6. As a result of the increase in temperature the soot in the filter will be burned off. If the DPF symbol does not go out, the driver should contact an authorised Volkswagen repairer and have the fault rectified. At 5. 5 soot loading the DPF light is lit on driver display panel. At this point the customer should follow the advice in the handbook. If they ignore this information and continue driving the vehicle until the soot loading reaches 7. At this point the customer will also be complaining of lack of power, etc. At 7. 5, regeneration is still possible with the use of the VAS tester. Only when the loading is above 9. DPF unit.

The Warranty department has confirmed that if there is no fault on the vehicle and DPF regeneration has been unsuccessful due to the customers driving style and the customers failure to comply with the instructions in the handbook, DPF replacement will not be paid for by warranty. Common causes for complaint Frequent short journeys Regeneration conditions are not met. Not recommended for sale in the Channel Islands and inner city driving. Customers who continue to drive the vehicle with DPF light on Continueddriving with the DPF light on and without successful regeneration results inexcessive soot loading of the DPF, to a point where it is above 9. At this point regeneration is not an option and replacement of the DPF isnecessary. Fault 1. Common fault code. This doesnot only relate to the DPF itself, but the entire exhaust gas handling system. Thiscan be caused by defective temperature sensors, pressure sensors, additivesystem components if applicable, poor connections, wiring issues, etc. Important Information Before diagnosing a problem vehicle or attempting to perform an emergencyregeneration, it is important to obtain a full diagnostic log and read out relevantmeasured value blocks. These MVBs contain important information on thecondition of the DPF system and are essential in diagnosing the fault. When the. DPF light is illuminated, it does not necessarily mean that the DPF requiresregeneration. For further advice, please contact Technical Support with theinformation from the diagnostic log and MVB data. If a problem vehicle arrives with the DPF light, the engine management light andthe emissions light on. If during your diagnosis and reading of relevant MVBs,you find that the soot loading exceeds 7. VAS tester. Further to this, the customer needs to be educated. They need to understandwhy the lights have appeared on the dash panel. Their attention needs to bebrought to the owners handbook instructions, so that they are aware of what the. DPF light means and what to do when it appears. This should preventunnecessary repeat visits for regeneration purposes. I have also found that as the car gets older 3. K miles, you will notice that the regeneration takes place more often. ALWAYS, check your oil before any long journey, as DPF regeneration can use a fair bit of oil. Some questions and answers that may help Question The glow plug symbol is flashing. Why What should be done Answer The DPF regeneration has not been completed during normal driving and now DPF has reached its maximum saturation at which it can still be regenerated. The limit value depends on variant and Model Year,but is in the range of 1. Possible causes for this are a. Frequent short distance journeys, i. DPF does not take place because the conditions necessary were not fulfilled. Frequent interrupted regenerations, i. Applies to short journey drivers who have at least fulfilled the conditions for triggering regeneration. If the glow plug light flashes, the vehicle a. Engine running since start forlonger than 2 minutes. Calculated saturation higher than 8. Coolant temperature over 7. C for at least 2 minutes. No DPF relevant faults stored in system. A defined vehicle speed threshold must have been exceeded e. Question Under what conditions is regeneration interruptedended once it has started Answer Normally when regeneration has been successfully completed, or a. After a maximum regeneration time 2.

This is the second iteration of this article. It has been updated to reflect the common problems that are encountered when tackling what are understood to be DPF blockages. In this article we will address the following questions What is a DPF Why do DPFs clog up Misdiagnosis and related common faults. Reasons why a DPF cleaner may not work for you The correct logical steps to diagnose and fix a DPF blockage. What is a DPF A DPF or Diesel Particulate Filter is a device integral to the operation of the exhaust emission control system. It captures particulate matter and hydrocarbons, stores them, and every so often a process of regeneration occurs where these deposits and particulates are burned off, converted to CO2 and vented out the exhaust. Why do DPFs clog up There are a number of contributing factors. The first is the quality of the fuel. The second is the quality of the engine oil and the third, driving style and journey type. Diesel engines in particular are not designed for short journeys or stop start driving and such conditions create an excess of particulate matter in the emission control components. That means that the DPF as well as other parts such as the EGR and catalytic convertor have more particulate waste to deal with. The issue arises when the engine is producing more particulate matter than the DPF can cope with. A variety of symptoms may then become evident such as engine hesitation or power loss. Eventually an engine warning light that informs you theres an issue with the system, and if not resolved the vehicle is then put into a limp home mode, with reduced power. If the system is clogged excessively, it is common for the ECU to prevent further regeneration. This is very lucrative for some dealerships and garages, because in their view, it means you have to replace the DPF, which can run four figures in cost. I can tell you categorically, the DPF can be cleaned unless it has failed catastrophically, even if its 1. It can also be cleaned even if the ECU will no longer force a regeneration cycle with the help of diagnostic software. Furthermore, modern cleaning techniques and technology means that the DPF does not have to be removed to be fully cleaned but more on that later. It is important to note that particulate matter that accumulates in the DPF is NOT just from the fuel and the combustion process. Its normally a combination of those elements, as well as engine oil. Oil can be blown through the crankcase breather system, but more commonly on a diesel engine, it bypasses the piston rings and is poorly combusted. Those particulates then accumulate in the DPF. This is the reason you have mid SAP and low SAP oils. The theory is that such oils have lower ash content, which gives the DPF an easier life. In some cases, high ash content can damage the DPF because it isnt able to combust those types of particulates. Our experience actually differs from this as higher ash oils can prevent oil being bypassed in the first place. However, that is a different subject for another day. Resolving a Blocked DPFFirstly, one of the most common mistakes is actually misdiagnosis. An emission control warning light or even a DPF warning light does NOT ALWAYS mean the DPF is blocked. This is much more common than you think so do not assume the DPF must be blocked if your vehicle produces a DPF warning light. For Example Emission warning lights are normally shared across the entire emission control system so an EGR exhaust gas recirculation valve fault or similar can be the root cause of what first appears to be a DPF issue. One of the most common faults is that the Pressure Differential Sensor that calculates the saturation level and reports an over saturation condition to the ECU could be faulty. In other words the DPF is fine but the sensor is reporting excess carbon and preventing a regeneration cycle. These sensors should be one of the first things that are checked but they are often ignored. The result is an unhappy customer as the cleaning product or process didnt work. It probably did but the sensor is just reporting otherwise. The ECU has identified the pressure sensor as faulty and it is this that needs to be replaced rather than the DPF cleaned. Secondly, and more important than the first there MUST be an underlying reason for a DPF blockage if, in fact, it is actually blocked. The underlying reasons should be established and where possible, addressed accordingly. For Example Fuel system deposits resulting in an inefficient combustion process can produce more carbonaceous matter than the DPF can manage. This can also apply to using low quality or incorrect specification oil. Is the engine consuming oilDriving style and journey types. Certain conditions must be met to enable the DPF to regenerate and manage the carbon build up. Continuous low RPMs, stopstart driving and short journeys that do not permit the engine and DPF to reach full operating temperature will eventually take its toll. Other underlying faults such as an injector or EGR issue could be preventing the DPF from regenerating. The ECU recognizes an underlying fault and locks out or prevents DPF regeneration cycles. As above, the pressure differential sensor is just faulty and misreading the level of backpressure between the front and rear of the DPF. Saturation level is only 1. Therefore, as best as you can it is important to establish if there is a DPF blockage and if there is, or high probability that there is, to identify the root causes. If not, you will be fighting a losing battle. This is why fuel based DPF cleaners and professional DPF cleaning is so hit and miss. Many users fail to correctly diagnose andor address the actual root cause. If a fuel based DPF cleaner did not work then there is a good chance that the actual fault is not directly DPF related or that an underlying problem is forcing you into lose lose position. It is not always as straightforward as many make out but I am going to make it as easy as I can for you. Logical Steps to Resolving Suspected DPF Issues. STEPSACTIONAPPROX. COSTS1. Simple. If you suspect the DPF is blocked then before you spend a penny on diagnostics or treatments do this Get the vehicle up the full operating temperature, drive down the road and drop a couple of gears to get the engine revs above 3 3. In other words try to force a DPF regen. Free other than the cost of fuel. Basics. If the above fails then you need to make the choice of using a fuel based cleaner andor investigating further. If using a cleaner then combine it with step 1. It is a reasonable low cost process of elimination. I would recommend a high strength fuel system and engine cleaner first before using a dedicated DPF Cleaner OR use a fuel cleaner with combined DPF cleaning function. A basic OBD CAN BUS code reader can be purchased for as little 1. I recommend everyone keeps one in their car. If warning lights are visible then the ECU will have stored codes and rather than blindly guessing you are well on your way to correctly diagnosing the issue or any underlying problems. If the codes do indicate a DPF saturation issue then this may be enough to justify using a high quality fuel cleaner andor dedicated DPF cleaner.
