SOURCE: p0471 and p2002 codes, Audi A6 2.0 DPF S-Line Auto

A6 2.0 TDI 1997
Got same problem around 35000Km. Engine light on with same error P0471. I was in France, Audi reset error and found nothing suspect. 4 weeks later same problem. (I felt engine was executing filter regeneration cycle very often). After 1 more week, Exhaust symbol came into large display and engine into safe mode (max 90Km/h). Contacted my Audi dealer in Belgium. They immediately told me pressure sensor (measures obstruction over DPF) was defective ; happens more often. Car was just beyond 2 Y old. Replaced under warranty. No more problems.

HOW DO I RESET CODES FOR 2010 D13 ENGINE FOR ATS REQUIRED DERATE ACTIVE.I ALSO HAVE SOOT LEVEL HIGH...--WHATS IS KEEPING MY ENGINE FROM REACHING PROPER TEMERATURE TO DO A SUCCESFUL REGEN


Code Resets are done via a Code Reader.

High soot is caused by rich mixture.

Not reaching proper temperature is either a faulty thermostat, or the fan thermostat is broken and the fan is running all the time.

My bongo is flashing dpf wat should i do. And in gear 3 it stops pulling


Dpf stands for diesel particulate filter which is sooted up in the exhaust system sometimes you can burn the soot out by running at high revs for a while in a low gear to burn out the soot if that don't work a new filter will need to be fitted but don't leave it to long as it can damage the engine and turbo which will need replacing the turbo that is

On my Peugeot 5009, why did the DPF warning light come on after only 23000 miles?


If this is a diesel eng the Diesel Particulate Filter(DPF) is plugged with soot. excessive idling can plug up the filter in several hours on some vehicles. Check your owners manual to see how to do a regen (burn) to clean out the filter. Sometimes just running eng hard at hwy speeds will burn out the soot also.

check your owners manual to see how to do a regen (burn) to clean the soot out of your dpf (diesel particulate filter) do this as soon as possible or the engine may go into derate.

Error code 55 on vauxhall meriva whats it mean


Error 55 is Diesel Particulate Filters (DPF)
Reducing diesel soot emissions by 80%

If you're buying a new car and plan to use it mainly for town-based, stop/start driving it would be wise to avoid a diesel car fitted with a Diesel Particulate Filter (DPF) because of the possible hassle of incomplete 'DPF regeneration'.

The exhaust emissions standards for new cars have effectively required fitment of a DPF in the exhaust of diesel cars since 2009 when the 'Euro 5' standard came into force. In fact, many cars registered before 2009 will have had one fitted too in anticipation of the change in standards.

Standards aim to deliver an 80% reduction in diesel particulate (soot) emissions but the technology's not without problems - AA patrols are regularly called to cars with the particulate filter warning light on indicating a partial blockage of the filter.

Even if your driving isn't mainly urban/stop-start, changes to driving style may be required to get maximum benefit from these systems.

How do they work?
Diesel Particulate filters (DPF) or 'traps' do just that, they catch bits of soot in the exhaust.

As with any filter (think of the bag in your vacuum cleaner) they have to be emptied regularly to maintain performance. For a DPF this process is called 'regeneration' - the collected soot is burnt off at high temperature to leave only a tiny ash residue.

Regeneration may be either passive or active.

Passive regeneration
Passive regeneration takes place automatically on motorway-type runs when the exhaust temperature is high. Because many cars don't get this sort of use car manufacturers have to design-in 'active' regeneration where the engine management computer (ECU) takes control of the process.

Active regeneration
When the soot loading in the filter reaches a set limit (about 45%) the ECU can make small adjustments to the fuel injection timing to increase the exhaust temperature and initiate regeneration. If the journey is a bit stop/start the regeneration may not complete and the warning light will come on to show that the filter is partially blocked.

It should be possible to start a complete regeneration and clear the warning light by driving for 10 minutes or so at speeds greater than 40mph.

If you ignore the warning light and keep driving in a relatively slow, stop/start pattern soot loading will continue to build up until around 75% when you can expect to see other dashboard warning lights come on too. At this point driving at speed alone will not be enough and you will have to take the car to a dealer for regeneration.

Expensive repairs
If you continue to ignore warnings and soot loading keeps increasing then the most likely outcome will be that you will have to get a new DPF costing around £1000.

DPF additives
The most commonly fitted type of DPF has an integrated oxidising catalytic converter and is located very close to the engine where exhaust gases will still be hot. This heat means that passive regeneration is possible.

There's not always space close to the engine though so some manufacturers use a different type of DPF which uses a fuel additive to lower the ignition temperature of the soot particles so that the DPF can be located further from the engine.

The additive is stored in a separate tank and is automatically mixed with the fuel whenever you fill up. Only very small quantities are used though so a litre of additive should treat around 2800 litres of fuel - enough to cover 25,000 miles at 40mpg.

You will have to pay to get the additive tank refilled at some time in the car's life, and we've heard reports of dealers charging up to £200 to re-fill a half empty tank.

AA experience
We're seeing some evidence of DPF systems failing to regenerate even on cars used mainly on motorways.

On cars with a very high sixth gear the engine revs may be too low to generate sufficient exhaust temperature for regeneration. Occasional harder driving in lower gears should be sufficient to burn off the soot in such cases.

With this type of DPF regeneration will be initiated by the ECU every 300 miles or so depending on vehicle use and will take 5 to 10 minutes to complete. You shouldn't notice anything other than perhaps a puff of white smoke from the exhaust when the process is completed.

There's no evidence in AA breakdown data that the problem's going away - newer car models seem just as likely to sufffer DPF problems if not driven 'correctly' as those built when DPF's were introduced.

Check the handbook
If you buy a car with a DPF fitted it's important to read the relevant section of the vehicle handbook so that you understand exactly what actions to take if the warning light illuminates and how, if at all, your driving style may need to be adjusted to ensure maximum DPF efficiency and life.

If your cel is on and engine has derated you will have to take it to a dealer. They will have to clear DPF level in the ECU and then force a regen using a laptop. There is no other way to reset the system.

The DPF is designed to 'Burn off' the soot deposits that accumulate, but in order for this to happen the exhaust has to become really hot. The DPF will fill up if the vehicle does a lot of short trips and the exhaust fails to get hot. The cure is a long hard drive
