    Default Dipped/Low Beam no 12v on them

    Hello, so my car's low beam lights are not working, the high beam and the other lights are working fine.I've checked the fuses everything seems fine there, when i check on the low beam "sockets" they don't have the 12v they should have (0 power).What can cause this problem? Any help would be much appreciated.

    UEC is normally the culprit but did you check the fuse f8 (and f9 if you got HIDs) on the fusebox next to the UEC? if those seem to be fine replace them anyway... I found that old fuses cause problems on these cars... if that doesn't help you might want to take the UEC apart and clean it as the circuit-board within can have some corrosion on it causing the problem...

    and make sure you clean the connectors to both the headlights with an electrical cleaner just to make sure..

    also you missed this
