All, I have a 2005 A8 and on my morning errands this morning, the MMI screen stopped working (but the radio stayed on) and after turning my car off, the radio stays on?! I've done several MMI resets and no luck. I've had quite a few issues with this car over the years but this is a particularly unique one. Any ideas on where to start would be most appreciated. Thank you.

What happens if you press down the volume control and hold it down for a few seconds?

VCDS scan? That will tell you a lot about what is going on.
