Sunroof / Moonroof Clutch: Service and Repair
ADJUSTING SLIP CLUTCH ON SUN ROOF MOTOR
Note: The slip clutch was adjusted in the factory and only has to be readjusted, if the adjusting screw had been removed for manual operation of the roof. The lock nut is cemented on the adjusting screw at a distance of 2.5 mm from the screw's head.
To guarantee perfect operation of the slip clutch, the adjustment should be made by measuring the power input of the sun roof motor.
1. Remove fuse no.9 in extra fuse box. Connect ammeter on fuse carrier no.9.
2. Screw in adjusting screw on slip clutch and tighten slightly.
3. Turn on ignition and operate switch to move lifting roof lid to final position of drive. Measure power input in final position (clutch slips).
4. Tighten adjusting screw until power input is 12 to 14 amperes.
5. Disconnect ammeter and install 25 ampere fuse again.
