The battery is flat and/or not charging which is a common issue on these when the signal wire from the alternator to the battery controller fails.

At the moment you need a new ignition switch, a fairly common problem and easy to deal with.

HiCrasher

Thank u for the quick reply .

u mean this one :
audi a6 c6 ignition switch replacementþ - ÈÍË Googleþ

does it need programming or coding , I am going to buy a used one , I have VCDS

please help and advise

regards

Adel

Yes, the unit is not keyed to the car, I assume they didn't feel it was necessary so any key of the correct type will turn the switch, the anti theft function is provided by the chip in the key.

Thank u so much , I will buy a used one and let u know .

Crasher by the way do u have wirig diagram to the head light modul Central Electro 4F0 910 279 K

Led light are not working in both side , my car is 2007 model ! please help

Adel

It won't be wiring, get rid of the HID system and recode the central electrics to remove hot bulb monitoring.
