  • 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 a 2017 A4 Allroad and the MMI reset was easy but didn’t solve my problem; Vehicle Drive Select is in Red and won’t let me change the drive mode (into off road or otherwise). Trunk door foot release isn’t working either. What a pain!
