Audi TT Cabrio problems with the DPF

Hey guys, my 2015 Audi TT Diesel is behaving strangely. When accelerating, black smoke comes out of the exhaust, the check engine light is on and the engine power has decreased. I have also noticed that the DPF regeneration is not working and the exhaust smells strongly. Could it be that the diesel particulate filter is heavily loaded? How have your garages solved this problem and what has been your experience? Any help is welcome. Thanks in advance!

Hi, I had a similar problem with my 2013 Audi A4 diesel, I only have some experience with cars but it sounds like a faulty diesel particulate filter to me too. At my garage they replaced the filter, it cost me about 1550 euros. It was a bit expensive, but apparently the diesel particulate was defective due to high mileage. Could you also tell me how many kilometers your TT has already run? That could help solve the problem. Hope this helps you!

Hey, thanks for the quick reply! My TT already has 224678 km on the clock. The last service was only recently, but the problem was already there. So, it could really be the diesel particulate filter. I hope this helps to narrow down the problem. Your repair costs don't sound too encouraging though, I must say! I really hope it won't be that expensive. Thanks again!

No problem, always welcome! With the number of kilometers and the symptoms already present, I would strongly suspect that it is the diesel particulate filter. With so many kilometers, the filter can already be heavily loaded. And yes, I know the repair costs are really high, but I had peace of mind afterwards. Maybe you can get a second opinion from another garage to reduce the costs a bit. Even if it's going to be expensive, I wouldn't put it off, otherwise it could get even more expensive. Good luck, hopefully you'll get it sorted quickly and cheaply!

Thanks, Dude! Yeah, I'll probably go to the nearest garage and get a second opinion before I make a decision. In any case, I'll tackle the problem now before it gets worse. Thanks for the tips and help, that was really helpful!

Hello everyone, I drive an Audi A4 2.0 TDI 190 hp. Previously, my engine control lamp illuminated... I quickly read it out, error P200200 Efficiency of particulate filter bank 1 below threshold. The car runs without problems and I have no loss of power or smoke formation while driving... What could be the cause?

Start by checking if the diesel particulate filter (DPF) is clogged or partially blocked. Sometimes, a long drive at highway speeds can help regenerate the DPF if it's not too clogged. If the issue persists, it might be worth inspecting the DPF pressure sensor or the exhaust temperature sensors, as they can sometimes cause false readings. Keep an eye on the situation and let us know if the problem continues or if you have any further questions.
