I have a 2007 550i which I purchased about six months ago. I didn't notice it at first but it seems like the cabin is a bit loud at highway speeds. The noise comes mainly from the sunroof area, especially when the sunshade is open. Never had this problem with my 335i coupe.
I'm not getting any water penetrating when it rains or from the car wash. The dealer thinks replacing the seal and reprogramming the sunroof
might help -- at a cost of $400+.
Anyone have any experience with something like this? Ideas?
(and because everyone hates posts without pics I'm attaching an old favorite)
