I have a 56 plate 3.0tdi quattro cabriolet. I've had a read through the posts to try and point me in the right direction. The dpf light came on two days ago. Its happened before but driving as instruceted as always cleared it. This time I've done the same but the light wont go out. I've driven near enough a hundred miles in the two to two and half thousand rpm range but it looks like its not working this time. Spoken to Audi, the car is booked in and I'm advised it will cost around a hundered and thirty to resolve the issue. Im also advised I can still drive the car provided there is no loss of power! I happy to take it to the main dealer but at the same time I don't want to pay over the odds if a resolution could be found cheaper elsewhere? Also from experience is their a better way to drive the car to get the light out, have to admit I got a little frustrasted yesterday and used all the rev range but it didn't make a difference!
