Head lamp bulb chance on audi a6 2005?

BULB SOCKET HAS SOME CORROSION IN THEM NEED SPRAY SOME ELECTRICAL CLEANER CLEAN CORROSION. OR YOU HAVE ELECTRICAL PROBLEM IN THE CONTROL MODULE THAT CONTROLS REAR LIGHTS.

Front bumper cover has to be dropped down to be able to loosen headlamp unit enough to get to the back of it. Dealer will probably charge an hour for labor.

how do you remove headlight assembly drivers side on audi a6 2001

If you have headlamps failing and bulbs do not do the trick, the headlamp switch is your culprit and should be changed very very soon. Let me know if you need anything else. I have diagrams.

First remove the driver's side fog lamp plastic cover out from front bumper. After that you will find torx socket head panel screws from fog lamp. See picture below:

I am not sure but I think you need to change the whole headlamp, at least that is how it works in A4.

pull it away from left to right it is only pushfit...

I had a problem with rear left side signal brake and reversing lamps not working on my 2007 A6 2.L Tdi SE.( Intermittent fault for 2 months)
I think I have identified the problem.
The seal between the Lens and the bulb plate had allowed moisture into the lamp.
During sunny days the water evaporates and enters the multi pin connector at the rear of the lamp.
On close examination of the connector I noticed minor discolouring of the ground ( Heavy Brown Wire connector Causing intermitting lamp failure )
SOLUTION
I expelled all moisture from the lamp and multi-pin connector.
I removed the neoprene seal from the lamp and refitted it good side up
I cleaned the ground pin on the connector with 600 grade paper and contact cleaner
I put a slight twist in this pin with long nose pliers so as to get better connection.
Lamp is working fine since.
Changing the bulb plate may also work
Great care must be taken when changing bulbs or this problem will reoccur

you need to remove the headlamp assembly to change the bulb should be held in with 3-4 10mm bolts

lights are on
