Hi guys,

Just bought a 2007 A4 S-Line and it has some quirks with the electrics!

First of all, the controls on the steering wheel don't appear to work with the Audi Concert radio despite both being apparently factory spec fitted.
Secondly, unlike my previous A4s, the radio doesn't switch off when I turn off the engine and remove the key, and whilst the car is unlocked, the electric windows still work with the engine off and the key out of the ignition.

I can live with the radio/ignition thing but would like to get the steering wheel working with the radio etc. Does anyone know what it's likely to be?

Thanks!
