Hello, I need the help of the experts. After I noticed that the Xenon light throws only a few meters in front of the vehicle light I commissioned a well-known friend to check the headlights. We noticed that neither an adjustment of the light throws nor a post-regulation occurs when we load both fenders with our body weight. In the on-board computer no error message is timed. So the Xenon light up But there is no adjustment. I should mention that a lowering set was installed about 2 months ago. Reading the ECU via the Bosch Tester was not possible Does anyone have any idea what’s going on ?? Thank you for your help …
