Further to this sunroof thread I wanted to comment about the sunroof on my 850csi. It rattles and has done so ever since I bought it. Three different dealerships have been unable to fix it. The rattles come from the front of the sunroof whenever I hit small bump at speeds over 50 or 60 mph. It's very annoying to say the least. Sometimes I have to crack the sunroof just a bit in order to quiet it down. Anyone have any ideas on this? Thanks.
