Same with my 95 M3, got it for 2 weeks now, I thought the iddle was a lil bit rough when i bought my car. Replaced spark plugs, clean air filter. Still run the same, then I just bought the Fault scanner, and says i have Knock sensor 4-6? Im not sure if its a bad sensor? or it means something bad going inside my engine.

Engine runs perfect when stepping on gas, its just when its idling. Engine light is not On, I guess its not a priority error?


Needs your guys input, me and driva looks like have the same problem.

Thank you guys,
Will appreciate for any inputs or suggestions

yeah me too, engine knock while idling, my mechanic ran my codes, then cleared the codes, then told me to drive it for a week and then to come back and he would make his decision on what to do, im guessing hes gonna tell me to replace knocksensors
