My 4Motion has Auto Wipers and auto dimming rear view mirror, but has a standard light switch. I'd like to retrofit auto headlights but do it as OE as possible. Because I have the rain sensor etc, I'm assuming that this should be fairly straight forward yet I cannot find any detail on this. Does anyone know what additional wiring I'd need to do & programmign in VCDS outside of buying the OE Switch.
thanks
