Got in from work tonight with my 90 Quattro(1988) to find the Nearside tailight out.
Bulb me thinks No Umm Fuse (No7 in box ) no...Front sidelight on.
Strange one? 12v missing to tailight grey black wire traced her back to a strange junction box screwed into the inside of the rear Nearside wing. Still no 12v getting to that.
Haynes has this joining the front circuit before the fuse and therefore the dash switch is this right, Have I missed something obvious .
