Hello, I lost my incandescent bulbs, the next day I changed the bulbs to different ones, the lights still did not work, the next day I bought another, they still do not work. Road and position lights, they function normally, I checked the fuse 3 times, manually and with a multimeter, I turned the light switch on, there was no burning, no smoke. I installed the second switch and no change, I still don't have dipped headlights. I changed the switch the next day from a colleague's Passat, it works with him and is functional for me, there are still no dipped headlights. I don't know what may be wrong anymore. Is there a relay for dipped headlights in a3 8L? to have dipped-beam I changed the pins from the long lights. I just don't have power at the low beam.
