Hi all

New to this so please bare with.

Recently bought a3 2.0tdi 2006, the previous owner has fitted genuine zenons from what i can only think have come off an S3 or something that comes with zenons.
Problem being when i switch the lights to main beam they flicker and just give no light out at all, therefore not being able to use them on main beam.
Bought the car private sale so cant take it back!
The zenons have obviously not been fitted properly and on closer inspection have found 4 x grey wires coming out of the haeadlight on the drivers side that go nowhere .
Could anyone give me advice on hoe these can be fixed so that they work corectly, also keep getting bulb faults on the dash.

Would appreciate anyones perspective on this as i have read various different threads on the net but they dont sem to cover all aspects of my problem.

Please help!!
