E53 X5 Stuck Panoramic Roof - FIX
============================

Apparently, there are many E53 x5's with panoramic roofs that have suffered operating faults in the cassette mechanism which opens and closes the pano roof. The problem is that the rear portion of the roof sticks in the open position and does not close. If you do not want to run to the dealer to spend a huge sum in having the cassette mechanism replaced, a simple fix allows you close the rear panel permanently by disabling the rear roof mechanism.
The fix involves mechanically disconnecting the rear glass to allow the rest of the sunroof to function as usual. The “fix” is actually an irreversible modification to a portion of the cable drive mechanism, but the alternative is to go to the dealer and have them replace the entire cassette, which reportedly costs thousands of dollars.

The procedure is surprisingly simple & straightforward: manually crank open the sunroof, remove a retaining spring & guide bar, use a cutting tool (e.g. Dremel) to remove a triangular tab on the drive cable plate, repeat on the other side, then reinitialize the sunroof’s range of motion.
After the “modification”, all other functions of the front roof will work as usual. The front roof will tilt (vent position) and it will fully open (slide back). The rear roof will stay closed, but you will have saved on an expensive repair bill.
