Sorry to bring this thread up but recently my 12 month old E92 M3 has started doing this in the last couple of weeks.. took it to the dealer who just said there was nothing wrong with it and just handed it back to me still doing the random rev drop at idle.

I would appreciate anyone's comments as to what it could be or what I can do?

Thank you!
