OK a n00bish question I admit (but I did search the forum extensively with no luck before asking!!
I've just got an 2001 A6 2.5 TDI Quattro and the main beam and dip headlights are way off. I see one screw at the top of the headlight unit which appears to adjust height of the dip but not the left/right.
I'm driving the car back home tomorrow (looooong way) so need a bit of quick advice!
