Hi everybody, you don’t believe what happened to me. Yesterday on the highway while driving I wanted to clean the windows for a short time. I press the button for the window cleaning and suddenly the plastic cover flies away which covers the middle part of the wiper mechanism and it moves only a windscreen wiper. At the control at home I didn’t trust my eyes: the whole arm is broken! How about everything in the world can this happen? I’m curious what my NL says and whether MB acknowledges it as a guarantee case. Things exist … Gruss Uwe
