Dear SL community, today the weather was fantastic and I wanted to drive open with my SL, but the cover only went up half and then stopped. The cover on the left side was sometimes slightly loose and when it was out of the anchoring came the message “Find the workshop”. After I had locked it in again, everything worked again normal. But now it is very loose and just hangs down. I can’t see how I can fix it tighter again ( See pictures). Does anyone have an idea how to do this or what screw should I use? Thank you and greetings.
