Hello people. The TÜV has criticized the light output of my left headlamp. According to the workshop, the whole headlight has to be changed for 1100 €. I almost dropped the beer…. They could not tell me exactly what exactly should be defective of the headlight. I assume that maybe the reflector is blind? But I have no idea. What can I do now to fix the problem as cheaply as possible. Buy a used one? n new one at Ebay? Can you also change the reflector if it is at all? Thank you for your tips Greetings Guido
