b mike w 0 Report post Posted April 27, 2010 hey guys just wondering if anyone can help me. when accelerating under load (not in neutral) in between the rev range 1500-2000 there is a rattle in the engine bay. it goes away after 2000rpm and doesn't occur when i give it some guts. just wondering if this is anything to be worried about or if it could be a loose spring or bit of metal. thanks guys Quote Share this post Link to post Share on other sites

If you can't isolate the fault yourself I would suggest to be on the safe side to get it checked by a professional conversant with BMW's. It may be something minor, then again it may not. What fuel do you use ? are you sure it's not detonation (pinking) ? Quote Share this post Link to post Share on other sites
