Hello guys, I’ve got my Sl R230 ready for the summer. The most important thing, however, is that the roof makes me headache. When I try to open it, he drives down the windows a little bit and then doesn’t do anything. He also doesn’t show an error message on himself in the memory. I just don’t understand what it might be, maybe I’m doing something wrong, am I looking at something? I’m pretty desperate also my workshop doesn’t understand what it’s about The flap in the trunk is closed and the tailgate is also closed correctly. The only thing that is still striking is that the tailgate stays up only when you are held tight. It does not stand up….. Thanks in advance for your help.
