Engine misfire & Drivetrain malfunction
I have a 2015 x4 35i m package(180,000miles).
I drove on the misfires for much longer than I liked and the car threw itself into a limp mode after driving moderately through a neighborhood with a drive train malfunction and an occasional flashing engine light. After that I parked it and towed it to the dealer they recommended plugs, coils and all injectors for under 6k... took it home with the advice from the dealer. I've been chasing multiple misfires and lean bank codes. I've replace the coils, plugs, and injectors(EU5). I'm still reading misfire in cylinder 1 and 6 after replacement but the lean bank 1 & 2 are gone. The engine sounds terrible but better than it did before and is still in a "limp mode" and shows drive train malfunction. Thinking maybe its still fuel related HPFP or LP. I've also been told it could be VANOS solenoids. The injectors were mapped to the old ones when I replaced them. The pervious owner had EU6 injectors. Looking for any advice, thanks. |

OK reading live data is new to me I couldn’t find anything on my scanner about individual cylinders, but a lot of different readings in the live data stream. I was looking at the long term fuel trim I wonder if that percentage is too high?
Everything done at idle for five minutes See attached. |

Yeah, I’ve already swapped them along with the coils and plugs, also something to note it almost has a jerking motion when it’s in drive, pretty strong smell of something burning, no smoke seen. And a flashing engine light.
