I purchased a 03 a6 4.2 about two weeks ago and realize it had a headlight error on the display,"dynamic dimmer error" or something like that,I pulled the 10amp fuse for now and figured id figure it out sooner or later.
today I decided to replace my front brakes and saw a few missing items,it seems someone had cut the connector the level sensor was suppose to be attached too,see the 3 purple wires.i know I'll need a level sensor but what's the name of part that's at the end of those 3 purple wires??
