Hello colleagues, It’s probably a bigger evil, recently when it got decently warm I couldn’t open the roof any more. Then found out that the fuse 7 was defective, after exchanges it went through again, then I had a buddy who works at MB read the thing out, that probably didn’t work because on the control board conductor tracks for the pins 58 and 75 had burned down. The buddy meant the exchange of the control board was not risked, because the So it was, I ordered with my son a used control board from the internet, built in the same result. By now, I have recognized a Tw. short circuit for the pin 58, but I continue to tap without detail circuit diagrams in the dark. 1.) Has someone made similar experience, 2.) Can someone give me a source for the plans. so far first, thank you in advance greeting GBD
