Hello everybody :)
I post in this section because this engine is used in several BMW models.

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 engine replacement, 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 :

F30 335i klackern

I would like to know your opinions before removal of my transmission which is little pain.
Thanks for help (y)
