  • What do you do next if the re-boot doesn’t work? I have a 2008 Q7 and the MMI went dark abruptly just like a lot of the other vehicles. I checked all the fuses, connections etc etc and everything checks out fine. Tried the re-boot a few times and the system is dead as a door nail.


  • On a 2009 Q7 (LHD) the above procedure does not work. The SW version is 5570. Is there any other way to reset MMI? I am trying to do it because the Reversing camera stopped working and the Navigation says “Please enter the DVD” even though the Map DVD is in the changer in the boot…

    • Please check if you don’t have a leak in your trunk. Check all modules under the floor.

  • I have removed battery terminal and when I fix it then music system show the Audi infotainment system and music system does not work

  • Sorry for hijacking thread. I have a 2010 Q7 and I have to reboot my MMI if the car sits off for more than 45 minutes. why is it doing this?

  • Is there a button combination for the red (engineering) screen for the rear seat entertainment?

  • Hi,
    I had a liquid spill on my MMI control panel (A6 Avant 2008). Over time all the buttons ceased to work but I could still control it from the steering wheel. Every so often the control panel would light up and some buttons would work but very rarely. I’m guessing that one of these times I accidentally hit the off button and then had no way of turning the system back on.

    I managed to take the centre console apart and open the control panel. The circuit board was pretty sticky but I gave it a good clean and everything bar one function works now. Unfortunately the one thing not working is the centre knob/wheel. The press down button on the function of the knob works fine but when I turn it, it doesn’t scroll through the options like it should. When I have the face off I can control the censors on the circuit board with my finger but when I put the face back on and trythe knob for real I get nothing.

    Could you please give me some advice or trouble shooting tips.

    I thought about resetting the system but didn’t know if that would work also I was worried that I would lose all my programmed stations and have no way of retuning because the knob isn’t working (I’m guessing that a reset clears all tuned stations?).

  • 2012 Q7 with 3G+ now has red screen on when starting after trying to update to 2019 firmware. Any way to fix this or is it bricked!?
