DPF Error


Registered User
Hey, I was wondering if you guys could help me out.

I have a 2011 2.0 TDI A3 (140) I've been having problems with the DPF since I've owned the car, It continues to have an error then fixes itself then has another error. Took it to the garage (under warranty) and they said they couldn't find anything wrong with the car. but it's just come back again and its seeming to linger this time, Is there a fix or is it a complicated job?

I take it the garage was not a main dealer, what kind of warranty is it?. As TBH most after market warranties aren't worth the paper they are written on when you come to claim on them. You need to find out what fault codes are stored and go from there. Usually with DPF issues a sensor fails and this results in the DPF not regenerating often enough or not completely. The differential pressure senor on the DPF is a common failure.
Either way don't leave this as if the DPF is continuously regenerating , a possibility, then the sump ends up full of diesel and this can wreck the engine.
