Hello, I had a defective dipped-beam, I changed the bulb and that was still not possible, then in the engine room driver side replaced the 15s fuse and that still can not work. At the moment I do not really know, so I can start the other headlight works perfectly. Can possibly help me where the problem can be, so bulb and fuse are new. Would be happy about help. Thanks! Bulb for standlight is also through. But that’s not gan z so important. There is also a loose plug in it, I can’t assign it at all, it has such a white / yellowish housing, while the plug from the dipped-beam has a black housing, as if mass is missing, but everything else works, turn signals and driving lights no problem. H1 bulb and headlights with such a piston in Xenon optics, but no XenoN!
