I have a 2000 328ci coupe and recently I've been hearing really annoying rattleing sound from my passenger side door. It sounds like something is loose and rattling side to side when I drive. I think the Window maybe loose or something. If I press on the door, the rattling is stopped. Does anybody have any idea to fick this problem without spending alot $$$. Is it possible to take apart door and tighten a bolt or something.... if anybody know please let me know. It's really irritating me.... just thinking my baby is hurting somewhere.... but can't do nothing about it. Your suggestions, ideas, and information is much appreciated. Thanks.

Ive seen before a nut on the window regulator fell off causing the reguator to get outa balance and start destroying its self. THe person before you that owned if (if there is one) might have had to get the reguator replaced and whoever did it didnt tighten down the nuts all the way. Its a bit complicated to take the door pannel off. You need a few tools some might not have.
