I recently bought a 01 Screw with a sunroof. When I got it the sunroof was inoperable and leaked badly. I just spent all day rebuilding the track system. I highly recommend
The Sunroof Doctor - Your source for replacement sunroof & t-top parts! for the parts. The sunroof had come apart as described in the TSB. The roof now works perfectly and the rear of the roof no longer leaks because of the correct placement of the water trough. But I washed it right afterwards and I had a leak on the drivers side at the front corner of the roof opening. After seeing the inside of the roof the only place I can figure it is coming from is the drain hose that goes down the A-pillar because the seal doesn't look horribly bad. Anybody got any ideas?
