Looks like this maybe my problem as well after water got into my unit.

I have the exact same problem, I'm an engineer so went ahead and disassemble the center console and remove the MMI controls, it had and awful lot of gunk and spilled liquid just dried up. I cleaned the board with circuit cleaner, reflow the soldering
Joints and thought that would solve the problem, Nop it didn't I can't get pass the legal disclaimer. Before I buy a new control unit what would you guys recommend?

If you actually reflowed the solder and attempted to reset the unit and still get no where...I think you might be at the end of the proverbial road with the unit.

Sorry to hear that, but had you posted here a week ago, a friend of mine just sold there new (reman) MMI control unit in the center console for about $220 on ebay.

I can't say definitively that a new MMI unit will remedy your issue, but if you've already done the troubleshooting and are seeing the SAME issues as the OP (original poster), then I'd give it a go.

Have you check the amp? There's posting here or Audizine where the amp's went out and others where the MMI head unit fried. Have you checked the fuses in the boot has well?
Have you ran a diagnostics with Ross Tech Cable or VAG?

I have an 2008 Audi Q7 and MMI has been disabled for quite some time. I did however figure out how to reboot and bring temporary life back to the MMI screen. If you disable the negative battery cable for 5 minutes and fasten it back on, the MMI reboots and is operating. My problem if anyone has a solution is it turns back off within 48 hours? My guess is there is not enough power in the amp? Any solutions would be greatly appreciated!

2009 Audi A4 MMI boots up and shuts off
So I have been searching everywhere and tried just about everything in the book besides taking it to the dealer to figure out this problem. I ran the fibre optic loop back through each of the components, including underneath the glovebox. No joy. Checked all of the fuses and they all come back good.
One thing I have noticed though. All of the loop connections don’t blink at all, which I’ve been told isn’t a big deal, or have I been given wrong information? I haven’t seen anything like this online anywhere.
