I'm looking at a used RS6 that has a few gremlins, and I'm trying to put a price on them all before I (maybe) go forward with the purchase. One in particular is that the headlight height level sensor -- the car is on KW V3 coil-overs, and the symbol on the center digital display shows the headlights with a question mark (NOT the "dynamic headlight range control faulty" symbol). Tech confirmed the height level sensor is UNPLUGGED, but can't find the wiring harness that would plug into it (maybe it gets removed with the conversion?)... is there some sort of blank-off harness that should've been installed? Hoping someone with coil-over experience can advise how things fit back together with the mod, and how to get rid of the dashboard caution.

Thank you in advance!
