Maybe because the sunroof drain tubes run down the C-pillars?

 

Do you guys know if the sunroof cassette is covered in the certified series? If not this is a big job because I remember it got done on my 7-series because the roof was pretty noisy.

 

Okay, so my BMW Stealer fixed the water leaking problem, it was a blockage in the drains by the C-Pillars as some of the members advised and I got dinged for $250.00 labor charge. It's fine that I paid the charge but as soon as I got the car back the moon roof started to make noise sounds when I open or close it and the wind noise got louder than before. I called my BMW stealer and complained about the problem that I never had prior to my service visit, I was asked to bring the car back so they can check it. They had the car for the day then I received a call from the stealer to tell me that the new problem is not related to what they did in the last service and they need to change the seal around the moon roof and it is going to cost ~$350.00. I got upset especially since I did not have this problem before bringing the car to service, I told them not to do anything with it and I got dinged again for a $140 service charge as they claimed they worked on the vehicle for one hour. I pickup the car and this time I got a new noise which I hear all the time when I'm driving on a ruff surface, it is a piece of plastic behind the noon roof that keeps rattling. That being said, I have no idea what to do with the stealer, they told me that all they did to fix the draining problem was to drop the liner from the back. Now what if something got loose when they did that? The rattling noise is driving me crazy especially since my car was pretty quite vehicle. Any advise from you guys would be greatly appreciated. If you have any ideas for me to fix this problem, please share it. Thanks

 

This exact thing happened to me on my E39. The water channel that runs the length of the car, over the roof, down the side and to the back part of the trunk where it lets out was clogged. Water kept building up and eventually just made it's way into the interior and soaked the rear of the car. They ended up having to remove the roof liner and replacing the channels, where the water is supposed to run off through.
They also replaced all the pillars (A, B and C). After that, it never happened again, but my car was in the dealership for over a week. It sucked. Sorry to hear this.

 

This should not happen in a E60.

My 320iC '99's widows did leak some in the car wash.

 

lol this has happen to my e39 water ran in from the exact place... I replaced the trim, that fixed it....

 

This just happend to me today
Same deal: touchless carwash... I'm sitting there while it does its thing when I hear water dripping in the back. I turn around and sure enough water is dripping all over the seats from around both rear doors
What annoys me most is that I now have two water stains around the C-pillars.
In the six months I've owned this car I've gone to the touchless wash many times without any problems. Of course, over the past 15 years I've owned two Hondas, a GMC, and an Izuzu, and none of them ever leaked! I expected the same problem-free trips to the carwash with my $40K BMW.
I guess I'm sorta glad I'm not the only one to have had this problem. Back to the dealer for me... fortunately I'm still under warranty.
If anyone knows any quick fixes for this or preventative maintenance on the door seals, I'd love to know about it.
