Wierd radio problem solved...
 

When I got in the A6 in the morning, the radio was in limbo mode. (radio wouldn't turn on, radio wouldn't turn off, radio cluster lights stayed on with a blank screen).

Opened fuse access, pulled fuse 37, fuse was okay - so put fuse back. Wala... radio worked fine. It didn't even trigger safe mode.

So... what do y'all think? Common issue? If it happens again, how much (typical cost) to replace a radio? I suppose I could source a 3rd party radio. Or, maybe the battery (??)... just too wierd.

Sounds like your "reboot" took care of it...
 

...Pulling the fuse seems to have solved the problem this time, but maybe a VAG COM might give you some hints about what might have happened.

Re: Wow, this is so wierd, I had this exact thing happen to me this past Friday
 

on the way home from work. I did the same thing, and voila, it worked, with no safe mode. I tried turning it on/off a number of times, nothing, start/stopped the car, it stayed "lit up" lights, but no display. strange. Pulled the fuse and put it back in. works fine now, and no safe mode.

yeah... I know. No code. BUT.....
 

I did smell smoething when I opened the fuse
access. I was afraid that I might have an
arcing issue. A799, no code, no fault, and no issue at the time other than the blank "on" radio that wouldn't turn off.

If it happens again, I think I'll take it to the dealer and have them look for a code while it's "on" before I do anything else.

It's the only electrical issue that I've ever had, other than a blinker deallybob replacement.

Be carefull what you say...*knock on wood*

You just might get more than what you bargain for ;-)
