Exhaust weird sound

[Phahadx]

Hello,
I have this sound i will upload a video and im having a code saying its too rich.. the tuner says the car is totaly fine and there is no misfire codes or anything regarding injectors or coils or plugs. spark plugs, coils, injectors are all replaced theyre new just installed but i dont know what is this sound i think its o2 sensors or MAF sensors. its saying the car is too rich. the code is. 118111 mixture control 2, cross bank: fuel-air mixture too rich. and i cant post the vids of the sounds is there a way so i could upload the videos?

Id be asking bmw and checking injectors were programmed to car as they are piezo high pressure i believe and flow rate is stamped on each injector and has to be programmed

they are programmed there is no fault about injectors only this fault too rich. so injectors isnt a issue theyre new spark plugs new and coils new all new. i think o2 sensors or MAF sensors. but i dont know which.

had same codes and issues ended up being MAFS the second time I had this issue it ended up being the O2s. I would replace your MAF and O2s and that will fix the problem

hi

Did you fix this issue in the end ?

Your MAF or o2 sensor. I had the issue on my first m5 and one time new MAF resolved it and second time new o2.
