Audi A3 Cabrio problems with the DPF

Hi guys, I have a problem with my Audi A3 Diesel, built in 2016. It smokes heavily when accelerating, the indicator light is on and the power is gone. Even DPF regeneration doesn't work and the exhaust stinks. I think the particulate filter could be heavily loaded. Has anyone ever had similar problems and can recommend a workshop that could solve this well? I would also like to hear your experiences. Thanks in advance!

Summary of the thread

An Audi A3 Cabrio from 2016 is experiencing heavy smoke during acceleration, a warning light, loss of power, and a foul exhaust smell, suggesting a potential issue with the diesel particulate filter (DPF). The problem may be due to a heavily loaded or faulty DPF, possibly from high mileage. A suggested solution is to have the vehicle diagnosed by a reputable garage, where options like DPF cleaning or replacement can be explored.

Hi, I have had to deal with a similar problem on my 2014 Audi A4 diesel. I would say I have some experience with cars, but I'm not a real professional. My garage diagnosed that the diesel particulate filter was faulty due to high mileage, just as you suspected. The repair was not exactly cheap at 1550 euros, but the problem has since been solved. Can you provide more detailed information about your car, e.g. mileage, service history, etc.? It could be that your problem is similar, but without this information I can't get a clear picture. It's always best to get a proper diagnosis from a trustworthy garage. Best regards.

Hey, thanks for your quick reply. My Audi A3 Diesel has already done 223456 km and the last service was a few months ago. I also thought that the particulate filter could be the problem. 1550 euros is expensive, but if it solves the problem, I'm willing to pay. I will get an appointment with a good garage next week to have the exact problem diagnosed. Thanks for your advice and I'll let you know when I know more. Best regards back!

Hey, no problem, always happy to help! If your A3 has already run 223456 km, then the probability is indeed high that the particulate filter could be heavily loaded or even damaged. The cost of a new DPF can indeed be quite high, but it's usually worth it in the long run. It's a good idea to make an appointment at the garage. They can then check what's wrong in more detail and give you a specific cost estimate. It may be that only a thorough cleaning of the filter is necessary, which is usually cheaper. I'll keep my fingers crossed that it's nothing too serious and that it can be repaired in time. And please keep us posted on how it turns out. Best regards back!

Hello again, great that you are keeping your fingers crossed for me. Yes, I also hope that a thorough cleaning of the filter will be enough to avoid an expensive repair. Your information was really helpful. I will take your advice to heart and take my Audi in for diagnosis next week. I'll let you know as soon as I have any news. See you soon, and thanks again for your support. Bye!
