I'm off to the Nurburgring later this month. And am beginning the preparations for driving on the continent. One thing I really don't want to do is to use those horrible nasty stickers that dim your headlights right down, and leave residue over the lenses forever. Is there any way to adjust the headlights using VAG-COM as I've read on here for newer cars? Or something I can adjust on the light unit itself. I've heard mixed and varied rumours of both working on the B5. But I've not had chance to look. And not wanted to start poking around without knowing quite where I'm needing to look, or wether it's a fruitless search. Car's a B5 S4 Avant. Pre facelift. And has Xenons with auto headlight leveling. TIA.
