i had a very similar problem with my '02's moonroof. it got stuck open, the manual winding tool did not work, reset got it closed but not fully engaged. It was as if it were in the vent position but with the glass not popped up. I could simply push the rear part of the moonroof up and it would drop back down. The sliding shade would not completely close either.

i did some research and I think there are some clips that are prone to breaking. There are replacement kits available. The motor seemed to work fine. I live in a very hot and sandy area as well so maybe there is something to that theory.

I did not ultimately resolve this issue because I disposed of the X5, partly due to this problem.
