So I posted before about how something might be messed up in VCDS with my fog lights. But now my headlights no longer turn on automatically. I have been through VCDS and made sure nothing was checked that would disable this feature (unless I'm missing something). I had a Euro switch (with Auto). Car came with auto headlights that worked up until recently. Now I have to manually put the switch to ON for the headlights for them to turn on, no matter the light level outside (could be middle of the night). I have checked the switch and it's not that (put the old US Spec one back in). This leads me to think that the light sensor which tells your lights when to turn on and off may be bad. Does anyone know where this is located and what the P/N is? Any help is appreciated. Thanks!
