Check engine

Razvii21 · 03-09-2025, 08:54 AM

I have a BMW 520d G30 Xdrive 2018 amd bought it in December. At first it was a good car, but then it started giving me the drivetrain error but i could continue driving. Then suddenly in traffic it started smoking that i didn t saw my car in my back. It was the AdBlue pipe. Today the check engine light came on and it s smoking black... kinda a lot. Can anyone help me with an explanation?

I’m not a mechanic, but my uneducated guess would be that it might have something to do with the DPF being full and starting to regenerate. Of course, the easiest solution would be to hook up a computer and check for error codes. If you manage to solve it, share your experience—it would be interesting to know what happened!
