Hello first of all, I would have a small (big) problem. The roof can no longer be closed. Reason: the right rear window does not move anymore, so there is an error message in the system (thank God) and the process “close roof” is canceled. In the summer I had the same problem before, but after two days everything worked again without a workshop, just like that. But now the roof is open. Also not quite sooo bad, because convertible season at the end of October e h is over and because the roof has to be opened to the rep. of the side window. But now my question; does anyone know the problem? Does someone have experience with it? I will expand the part over the winter, if I can’t get it together, then I always have to drive open Who doesn’t know yet model R230 SL 600 Built. 2003. Thanks already in advance. Greetings Uwe
