Ikeep getting the Check Engine Light and getting 2 codes. P2002 DPF Filter and P0471 Exhaust Pressure Sensor Genertic codes. Can you advise as Audi say DPF filter although not changed till 12 years old is not covered by warranty.
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.

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.
