I took it in to be serviced, and they did not fix it the first time, in fact deleted that from the service ticket.

Brought it back, and they replaced the gasket - took 2 weeks, and the new sunroof was incorrectly installed - the bellows were bent and ripped the first time I opened the roof. And the paint on the roof was cut through to the metal, apparently in the attempt to remove the gasket. And BTW, the roof still leaked (into the rear storage by the radio).

The third trip to the dealer for this problem resulted in a replaced sunroof cassette and a new paint job. All was fixed.
