Question about 2008 Audi A6

1 Answer

I have been told by Audi that my A6 fitted with the dpf filter is "unsuitable for short journeys"! I have problems with it whilst within the Warranty period but they first appeared towards the warranty cover - now I have had to have the car in the garage 7 times and the filter has been replaced twice as it has failed to clear when carrying out the instructions they give to clear it. It is not easy to carry out the instructions whilst driving in the centre of London or any other town or city for that Surely Audi should have made it clear when buying the car that this problem could occur - if they told people that the car was unsuitable for short journeys then presumably no one would buy them?

SOURCE: Hi, my freelander is a 1998 S reg 2.0TDI.

Best to have a good dealer tech test this...they have more exposure to it and know what to look for... It is inside the transfer case and not easily serviceable unless you have experience with trans type gearsets. Don't forget though that I am not there and can't do more than make an educated guess...I'm wrong here much more often than I am when making hands on diagnosis only because I cant hear, see and drive your vehicle. That is why I always stress that you need to have hands on diagnosis by someone that is well versed in your problem. In your case, I really hope that it turns out to be something simple and less expensive!!!
Good luck!

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

The DPF is designed to be self-cleaning to a certain extent if the engine is run for a good length of time the deposits should burn off. I would kick up a fuss with Audi about the warranty, ask them to show its exclusion. Unless the DPF has become physically damaged by something you have done then they need to have it fixed as it is a result of the deficiency in their design. This is not like some damaged tyre, open to abuse by the driver, the DPF is integral to the vehicle operation and through no commission on your part it is not functioning as it should.

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.

C5 hdi sx 2.2 keeps saying unblock diesel filter


this is not referring to the dieselicon1.png fuel filter. it is referring to the DPF Diesel particulate filter which is located in the exhaust system.
to unblock it you need to make a 40min journey at or over 2500 rpm
(50 mph in 4th gear) this is known as a regeneration run.it brings the DPF up to around 400 degrees which burns out the old soot particles this is a normal process during normal driving but too many short /slow trips can cause a blockage in the filter

DPF FULL


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

2002 audi a6 transmission is in safe mode. What


hi, what it usually mean is that you have shifted down in to a lower gear whilst the revs where to high so then your gearbox goes into safe mode to protect it from further damage the only way to reset this is to take the car to a main dealers and have a diagnostic check done.

Let me know how you get on or if you need further assistance ok

Diesel particle filter keeps blocking


This is down to the way the vehicle is driven, if you are doing a lot of short stop start journeys the dpf will fill up a lot quicker than when driven on a motorway.
If you have an amber light and 'DPF FULL' displayed you can do a particle filter regeneration. To carry out a regeneration the vehicle must be driven on a motorway at around 60mph for approx 20 mins to carry out re-gen, there will also be a burning smell when this is complete.
If you have a red light and 'DPF FULL' displayed then there may be a fault which will require investigation.
