Well, I'm fairly new to Audis, but I know 1 thing and will offer
some extra advice.

What I know: Audi seems to use brown for ground wires, so you're
probably using something that's not a ground but seemed to be
at the time.

What I'd advise: NEVER guess on wiring.  When installing the
radio, disconnect the battery, get a good ohmmeter, and check things!
I'm betting you'll find that the grey-blue wire may have a few
ohms to ground.  If you don't know what a particular wire does
or where it goes, and can't deduce it from clever measuring,
don't use it.
