The VW supplies +12v permanent on the same pin as the Audi. It also uses the same earth pin as the Audi.
The exception is when you come to the switched live. The VW supplies power via the pin next to the permanent +12v. The Audi doesn't have this cable or a connector in the plug on the loom. I assume this is right as there is no loose cable floating about in the dash.

I have been told by my neighbour since I original posted, that the car was in the garage twice not once as he originally told me. the first time the battery was removed and the radio went into SAFE mode as stated above.

The second time the car went in (a non Audi garage), the battery went flat on the car while it was in the garage and to get the car started, the garage jump started it. Now I've read elsewhere on the forum that this can 'fry' the electronics if not done properly. Is this correct?

I have a now run a full scan on Vag-Com myself and is now reporting back that there are seven faults on car mainly to do with the Alarm and central locking system. It still also cannot read Radio or Central Conveinence Module.

It has reported that the Crash signal is active. Car hasn't been in a bump - well not since he's owned it.
A key fault (Key 1 fault) although no light is showing on dash
There is a fault with alarm sensor for tailgate and general alarm sensor triggers.
Not sure if this would be related to the battery dying or whether the garage have fried something.
