Audi A4 Sedan problems with the DPF
(Translated from German)
Summary of the thread
An Audi A4 Sedan from 2015 is experiencing issues with black smoke emission, decreased engine power, a check engine light, and a strong exhaust smell, suggesting a malfunctioning diesel particulate filter (DPF). The suspected cause is an overloaded DPF, possibly due to high mileage. A similar case with an Audi A6 involved a costly repair to replace the defective diesel particles, which resolved the issue. The suggested solution is to consult a garage for a professional diagnosis and potential repair.

Hey, thanks for your reply! My mileage is now 245678 km and the last service was a short time ago, when everything was still in order. But I'm afraid that, for better or worse, I'll get the same diagnosis as you... Let's see what they say at the garage. Damn, 1550 euros sounds like a lot. Did the repair take a long time? I hope that doesn't mean I'll have to hand in my car for a long time. I'll probably make an appointment tomorrow. Thanks for sharing your experience.

Hey, no problem, you help where you can, right? Well, the repair took me about two days. But that can always vary, of course, depending on how full the garage is and so on. And yes, it was quite a lot of money, but well, what can you do... I guess that's just part and parcel of being on the road a lot. I hope everything goes smoothly for you and it doesn't cost that much. Good luck at the workshop appointment tomorrow! Let us know how it goes.

Yes, you're right, with such high mileages you have to expect something like that. But two days sounds acceptable, if I'm honest. Well, I'll make an appointment and hope it's not too expensive. Thanks for your help and good wishes! I'll keep you posted and let you know how it goes. See you then!

Hey, I had a similar problem with my 2013 Audi A6 Diesel. My experience with cars is rather limited, but you always learn, right? So I took the car to the garage and had to accept the same diagnosis - "diesel particles defective due to high mileage". It cost a good 1550 euros, but afterwards the smoke was gone and the engine performance was the same as before. Could you perhaps give a few more details about your A4? Mileage, regular maintenance, etc.? That might help.
