The clacking noise is worse when the shade is fully extended. The noise quiets down when I retract the shade. Interestingly, I have a strong acetone smell that fills the cabin when the sunroof portion is opened up. On monday, as the weather here is now warmer, after driving with the sunroof open for 50 miles I noticed a decent amount of an oily substance that came out of the center hole of the hatchback upper section. I only see 2 rubber bumpers on the left and right side but the middle section there is a hole there with no bumper. Is there supposed to be a bumper there for a total of 3 or is it intentionally left without one? I'll submit pics this morning. Super annoying for sure!
I had a similar rattle in my car, at first I thought it was the sunroof, but after spending some time trying to isolate it, I realized it was really coming for the D-pillar trim. I would only hear my rattle when music was playing, FYI. If I put my hand on those trim pieces the rattle would stop. Ended up taking felt tape, folding it into small squares, and using them as a shim between the trim piece and the trunk cargo cover track.

As for the oily substance, I suspect it's the anti corrosion solution that BMW uses. A lot of users have noticed this substance leaking out of the doors where there's openings to allow water to escape. This is normal. On hot days it will get worse. The good news is, once all of the excess solution is gone, you won't have to worry about it anymore.
