Hello. I discovered yesterday that the motor that moves the sunroof forwards and backwards had fallen down from its mounting. I took the headlining out and found the two screws had come loose and the motor dropped down slightly meaning the sunroof did not move (the gear was not in place). It was a reasonably easy fix but there is no way of "torquing" the screws and I fear this may happen often. Anybody else had the same problem before?
