I’ve been trying for days to find a solution to my problem, but some threads end up only in the Nirvana and don’t get any further. The following: A workmate brought me his SL 500 Bj. 2005 because neither roof nor central locking went. I could do that with the roof by changing the fuse. However, the ZV still doesn’t go. When the remote control is activated you hear a clear cracking out of the trunk. I guess that comes from the ZV pump. The turn signals are turned on and the alarm system also seems to go partially. Partly because when the vehicle is locked with the emergency key and I then close with the remote control, then open again manually with the emergency key, without opening previously with the remote control, the headlights flash, but there is no sound. The thing is now complicated because my colleague has previously made the roof, but not already brought the trunk separation into the correct position. Now also the roof is not open and we do not have to turn under the battery. But the handle is still there.
