ghead I have been suffering form some belt noise on cold mornings on my 330i. It is only on initial start-upp and lasts less than a minute, but it is very annoying, and a little embarrassing. It has been to the dealership who cannot find a problem. After complaining to the dealer principle I managed to get them to replace the alternator belt and tensioners on Saturday. This morning it was cold, 3 degrees, and the noise is still there. Any ideas what it could be?
