BMW X6 M e71 2011 : black smoke, may long crank when warm, small irregular vibrations
Hi
No error code for the engine after diagnostic When cold start , start hardly (with pop and bang lol), smoke a lot (gray/black), gray smoke when full load on roads Fuel pressure regulator ? Oxygen sensor tired and reading bad value ? Injectors to be replaced ? Air filter ? https://youtube.com/shorts/5bWVbpVvryQ?feature=share Thanks for your help Patrick Last edited by kensou; 08-20-2022 at 11:25 AM.. |

thanks for your reply.
I think so also. BUt i wanna know others opinions. because no CEL, no logged error. Only one time, on a hard throttle on higwhay, after 20 mn of hard drive, i got LIMP mode, et got oxygen sensor voltage value excessive (after cat). and got something like injector issue on cylinder 1. If injectors are faulty , why i didn't get any error like mixture too rich ?.... |

Use BEST Fuel
The top-tier petrol has the best additive packages. Use the cheap stuff and you will see Reduced Power faults... even after ONE USE!
