Audi Q2 Diesel with indicator light, DPF regeneration error and black smoke - looking for advice

Hi guys! First of all, thank you very much for all your answers and advice. They have helped me a lot to prepare for what is to come and to better understand the possible causes. Last week I went to the garage to present my problems with the car. Believe it or not, it was exactly as you said - a glow plug wasn't working properly. The mechanic quickly figured it out and was able to replace it immediately. The overall impression was very professional and I felt like they really knew what they were doing. The good news is that the car runs much better now! No more black smoke, the start is back to normal and the Q2 is running much smoother now. The whole process was pretty smooth and stress-free. I was reassured to know that it wasn't anything more serious. In terms of cost, it cost me around 180 euros. So it wasn't as expensive as I had feared. Since then, my car has been totally reliable again and I am very happy with the result. Thanks again for your help and tips. They really made the whole process easier! So, drive carefully and always pull over when the indicator lights start flashing, you never know what it could be. See you next time!

Hi there! I must have had something similar with my 2015 Audi Q5. Don't let it put you off too much - it sounds like a classic DPF problem at first. There is increased soot formation when the glow plug fails, which then causes the regeneration to fail and produces more black smoke. It was the same for me, the cold start also took longer and there were problems with the pre-glow lamp. From your description, I would also guess that one of the glow plugs has given up the ghost. However, this is normal wear and should not usually be a cause for concern. It's best to go to the garage and have it checked, as it's quite easy for them to find and rectify the fault with these typical symptoms. So don't worry, it's really nothing serious. Good luck and let us know how it turns out!

Hey, thanks for the quick reply and the explanation! It sounds logical what you say and definitely takes some of the worry away. I'll pop into the garage as soon as I can. Do you happen to remember how much it cost you when you had the same problem with your Audi? And has anything similar happened again since then? I'd be interested to know so I can maybe plan a bit better. Thanks again and have a great day!

Hi, I had similar problems with my old BMW 530d. The glow plug had a problem, had to be replaced and since then everything has been quiet. The car runs like clockwork again, no annoying indicator light and no more soot. As to your question about how much it all cost back then: That was a bit tricky for me. Not only was the glow plug defective on mine, but there was also a defect in the wiring harness from the glow control unit to the engine control unit. If I remember correctly, it cost me around €395. Since then, I haven't had any more problems along these lines. I hope this helps you and you'll soon be able to enjoy more relaxed driving with your Audi again. Let me know how things turn out. All the best!

First of all, don't panic! As the others have already written, it's probably due to a glow plug that isn't doing its job properly. Such a malfunction could of course also have something to do with your 36,800 km, although that should still be child's play for an Audi diesel from 2018. However, it must also be said that it always depends a little on your driving style and driving style. If you only drive short distances or your engine is often cold, this can affect the service life of the glow plugs. The glow plugs are there to preheat the engine, and if they don't work properly, it will lead to problems with starting and combustion, which can also lead to that black smoke. A broken glow plug should be found quite quickly by the garage - it's not rocket science. Of course, the costs can vary depending on whether only the glow plug needs to be replaced or whether there is more work to be done on the vehicle, as in the BMW example you have already heard here. Anyway, I'll keep my fingers crossed that it's nothing serious and that your Audi will soon be fit again. Keep us up to date and have a good trip!
