Hi, i got problems with the bad sounds comming from the timing at cold start. Although it is just been changed at a mini/bmw workshop. They have changed everyting in there including the both of the vanos and one of the valve for the vanos. What can still be wrong? They say the sound i normal and shuld be there?!? Can it be a faulty new chain tensoner? Or a wrong one?
please help me.
thanks for any reply.

 

Could you post video/audio?


Year?

Are you the original owner?
Other service/repair done during your ownership?

 

Here is a video of the car and the nois.
