Hello everybody
I have a knocking noise on my 640i F06 2013 when engine is
warm and at
idle only in Park or Neutral. Car and shifting runs fine.
If I move to Drive or Reverse the noise goes away.
I have seen many videos on youtube and i don't found the issue in comments.
Sometimes torque converter, rod knock, exhaust bolt, normal..
I have already removed the belt to eliminate noise of front accessories. Noise seems coming from rear of engine or between transmission and engine.
Some links, it is always N55 + ZF 8hp45 combination :
I would like to know your opinions before removal of my transmission which is pain job.
Thanks for help
