Expert:  Steve replied 1 year ago.
it is something you mention. it is not a normal sound.
Expert:  Steve replied 1 year ago.
it is hard to tell remotely but I would suspect a belt driven component as the cause or possibly vanos related. definitely have it checked by a BMW specialist garage.

sorry i forgot to tell,i changed bobinas and spark plugs,i put beru bobinas instead delphi,i read one guy solved problem with changing bobinas some upgraded type of bobinas?
Expert:  Steve replied 1 year ago.
I think that is very doubtful, but you should be running Delphi.
Expert:  Steve replied 1 year ago.
unless the noise only started when you changed them, there is no reason to expect this is the cause.

there is no difference when i changed bobinas,that guy also changed vanos before,also i dont hear that sound until 10 min of driving,when motor heat up
Expert:  Steve replied 1 year ago.
exactly, there was no difference from the change, so there would be no difference changing them again, as I said. The noise, as far as I can tell from a phone video on youtube, sounds like vanos or something belt driven. the vehicle needs to be checked hands on with the aid of a mechanic's stethoscope to further diagnose.
