Hello, according to TÜV, my left headlight is “substantially” set too low. Now I wanted to see if it is done with a simple adjustment or if something is broken. Can I adjust the headlight with the screw in the green marked area? The screw can not be rotated properly. Since all this is only plastic I also do not want to use too much force. In addition, this “thing” can be pulled in and out in the red circle. The whole reflector moves horizo That’s not normal, is it? The screw can’t be rotated there either. But it certainly only serves the horizontal alignment?
