MMI/stereo Not working 2007 Q7

[RSFourMe]

My radio stopped working a few weeks ago. The splash screen will come on (with a weird red line running top-to-bottom on the far left side) and then go black. The splash screen will only come on once every 5 minutes or so...if I push the power button again after it turns off, it will not come back on. But if I wait a few minutes it will splash again...very strange!
Reverse camera doesn't work, no sound, no other input has any affect, nothing....any ideas?

The 07 Q7 has a manufacture flaw. The drainage from the sunroof goes to the 4 corners of your vehicle through tubes. Unfortunately Audi didn't think this through when they placed one of the drainage tubes directly beside all the electrical components in the rear passenger side panel behind the third row seat. Your Bose amp and other electrical components are located there and most likely the moisture has caused water damage. This happened to me, I speak from experience. If so, the amp may need to be replaced. The drainage tubes regardless if thats the problem or not need to be replaced and sealed properly because if it doesn't happen now it'll happen later.

Having bad MMI controls will do that too. I had this issue when soda got spilled into my MMI controls. PITA.
If nothing bad has happen to the MMI controls, check the amp, and everything else in the back right.

I sorta think this may be the problem. The am/fm button is pretty sticky....

But I'll go and check the electronics in the back as well.

Thanks guys

if the button sticks, separate the buttons from the circuit board and use a little bit of soapy water the run little bits of it around the buttons.

Feel like this is happening to me. Also noticed some water on passenger floor mat. Thing the drains are clogged. Any ideas on where and how best to clean the drains?
