I had the sunroof creak when going over uneven surfaces, driving into/out of the driveway, etc. I noticed the sunroof seal was pretty dirty so I cleaned it, which helped some, as did the weather cooling off I think. I then followed SIB 54 15 19 and bought the special grease (part 83-19-2-458-653; I couldn't get the part in the SIB, and it may be discontinued). I followed the SIB and sprayed it along the seal liberally; it's quiet now. I had a feeling it would work prior to a test drive, because before I could press down on the sunroof from the outside and it would creak loudly; after the grease, there was no noise. We'll see how long it holds up for.
