I suffer from this same annoying noise!! I was thinking of trying to put some thin foam on the upper side to lesson the noise! I'll be curious to see if anyone else has resolved this in some manner!

I have the same issue....makes noise when Open, not closed. I have not had a chance to work on this since my car has been in the shop since November. LOL...

awaiting solution. Doesn't happen to me except on tilt. Full open or partway not an issue.
I got tired of mine making noise so I got rid of the guts and disconnected the motor. Used a s small amount of clear silicone caulk around the gasket. Now it's "permanent". One of these days, when it's a fun day track car, and it no longer has a headliner, I'll get rid of all of it and have someone weld in a panel.

Mine did the same thing. The pivot for that metal piece in cruzan's picture above comes un-clipped from the piece that slides on the track and let's that metal piece rattle when the sunroof is tilted up. It's pretty easy to slide the "slider" into position and clip the pivot back in (with a coat hanger or similar), but on mine it came unclipped again a short while later. I think the tabs that hold the pivot in place just get looser over time. I intended to come up with a more permanent fix but then my car ended up totalled... Hope this helps.

Fix it correctly. Replace the entire roof with a carbon fiber one of a kind roof. It's just the thing to make it really pop!
