I have a 99 318is coupe and in the morning it starts grand and no noise from engine as such. when engine is warm and im changing gear when pressure comes off engine its lets a loud couple of knocks from engine. If i have car stopped and jus rev it the knocking comes in about 2500rpm and goes again after 3000rpm. Any ideas?? thanks

Problems like these are very difficult to diagnose over the Internet, but I would guess that it would be a chain tensioner that is beginning to fail. Replacement isn't too difficult. I can't think of anything else that would be obvious.
