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

[Crasher]

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.

[Adel75]

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

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