I would like to read more about this ramp at the rear they made so it slides up and opens. Mine is jamming at the vent position. I installed new motors.and cables and plastic wear pieces new left and right rear links. Only the left and right camblocks have not been changed.My sunroof issue version 1 sunroof, was a mechanical issue. It was physically being stopped from opening. Service centre fixed by making a ramp at the rear of the sunroof which allows it to slide up and so open.
