Hello municipality, I hope someone can give me a tip. to the error: for 1 week I have on the failure symbol, so read out, was brake light at the rear right (right because contact was something “Rostig”, contact ground with Dremel+Wirebrürstchen, again everything ok). However, I don’t understand this with the main light at the front left (outfall ONLY left) driving light (permanent light/light horn no light left) Are now new H1 Osram inside ! (both lamps exchanged). Error deleted, worked wi eder, both lamps light up when pressing the main light lever. Car complete, after 1 hour I wanted to shop…. Error again there = main light left does not work !!! So read out again, (same error) deleted and main light works again…hmmm funny. I was then shopping, the ignition again on….Fernlicht again left does not work (lamp for malfunction of the lighting again) The whole thing has been going like this for a week now. Have checked the contacts and also a bit fes The fact is, the new and old H1 bulbs/lamps are all heals (also cross-changed) and also the driving beam itself works until I close the car and about 1 hour do not drive. After 1 hour of standstill (closed) only the left driving beam is no longer working. What could this be about ??? Is there a relay for it or is there a controller/controller somewhere ? Can someone give me a Ra t. With the exception of the main light on the left, everything else works without any objection. I am grateful for every tip
