My 2005 A3 8p with normal halogen bulbs has the left headlight not working since today. The DIS shows the `left dipped headlight` error. When I went to replace the bulb I dicovered that there was nothing wrong with it. I checked the fuse and that is also okay. I tried disabling the cold diagnosis with VAGCOM thinking that maybe a faulty measurement that was causing the problem, but unfortunately that didn´t help. Is there anything else I can look at besides bulb and fuse? Maybe a relais?
