Vario Roof Will Not Open or Close
If you receive customer reports in the above model vehicles that the vario roof will not open or close, this may be caused by the piston rod of the roll bar
hydraulic cylinder twisting while extending and not being able to lock with the roll bar trigger solenoid. The roof is designed not to move if there are
issues with the roll bar system. Perform the procedure outlined below to resolve.
1. Remove the right side paneling in the rear compartment. Refer to WIS document AR68.30-P-4780R
2. Switch on ignition, press the roll bar switch in the UP direction until the piston rod (Figure 1, 1) is locked with the trigger solenoid Y57/1.
Note:
Aid of helper required. Guide the piston rod by hand so it can't twist while extending.
3. Lower the roll bar completely using switch.
4. Switch off the ignition and remove the transmitter key from the EIS control unit. Note: In vehicles with Keyless-Go (code 889), press the Keyless-Go
