[Es2] Help with RS2 headlight leveling electronics

[Steve Eiche]

Mike,
The headlight level control was mandated in Germany around 1990, so all 
vehicles manufactured after that time will have the ability to accept 
the motors.   All cars have some version of this system in Germany.

1.  Yes, the system is simple, if you already have the motors you are 
half way there.  You just need the control switch and some wiring.  Each 
servo gets three wires (X contact power, control and gnd) that go to the 
control switch.

2.  Active headlight control is required by law in the US with HIDs.  I 
have them for my ur quattro (factory on the '90 quattro 20V)

3.  It already is manual.  Only the new cars with HIDs got the automatic 
system.

If you want to adapt the automatic system from a new Audi with HIDs, 
that wouldn't be too difficult, but you would have to add the sensors to 
the suspension and add the control module.
