Audi A4 Sedan problems with the DPF

Black smoke from exhaust on acceleration

Check engine light on

Strong exhaust smell

DPF regeneration failure

Loss of engine power

Hey guys, I have a problem with my Audi A4 Diesel, year 2015. On the highway I notice that it emits black smoke while I accelerate and the engine power has also decreased significantly. The check engine light is on and I've noticed that the DPF regeneration is not working properly - I also have a pretty strong exhaust smell. My guess is that the diesel particulate filter could be overloaded. Have any of you had similar symptoms in your car? I'm particularly curious to hear what the garage did to your car and what your experiences were. Looking forward to your tips and advice!

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.

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!
