Have you checked to see if there's a wire loose under the passenger seat as this used to be quite a common issue on VAG cars.

Hi Steve is right its normally is the font passenger seat where it gets moved back and forth try disconnecting it and give the terminals a good soak with electrical cleaner, gets rid of years of crud build up, the only sign of a bad ballast is flickering of the light or no light at all.

Hi the most common place for wiring to break is where the door loom travels into the bodywork as for the headlights its normally corrosion in the connection socket that plugs into the back of the unit, bad earthing is the most likely culprit that causes no end of weired problems especially with the shutter system that controls high beam and low beam.
