looking for s4 wiring diagrams

[thejimrose]

well mark r has come thru for me in minutes. thanks mark!!

thanks to anyone else that was GOING to help but isn't as quick on the
'ol pdf-er-izer.

so it looks like the headlight leveling system consists of F+R level
sensors, a controller doohickey, and the adjusters servo's, which  use
a power, ground and some kid of reference. i guess i need to find a
car to play with to see what that reference signal looks like? then
figure out how to replicate it?

if there are any bored EE's out there who might have some input on how
to replicate what would be coming out of the control doohickey i'd
love some input. i'm crap with electrics and wouldn't even know if
what i'm thinking is feasible / possible. what i'd like to do is add
some kind of switch / controller to manually adjust the adjusters
[well, electrically/manually, not like, actually manually].

thanks all.
jim

ps ECS sells the adjusters for 35$ each 'for vw's only' but the part #
matches the b5 audi s4 part #. dealer gets $75.
