So i think our cars need to be driven often and longer trips !
Here is a video it's "not" my car ,but here the clunk noise is "very loud" !
This sound....sounds very bad,and can not be good for our engine
I have about 50 % loudness of the noise in the video !
There are a lot of people with this problem !

So in the video is the clunk noise very clear and loud........and hope that we can find a solution for this problem !

A buddy of mine was here yesterday who is a mechanic. Not a BMW mechanic but a good one just the same.

He said it sounds like the slack coming out of the timing chains on start up.

Do the tensioner's rely on oil pressure at all?
