Not really the place to ask, but since i'm comfortable in the Amibay forums i'll have a go anyway 
When the soft top is closed on my 2000 model BMW 3 series convertible there is a horrible rattle (heard on rough bumps on the lovely Maltese roads) coming from the front center part of the top (between the locking latches). Basically from where near the interior courtesy light is but obviously on the roof part.
Sometimes opening and closing again the soft top fixes the problem. Sometimes not.
In both cases (rattle or no rattle) the top locks properly.
