Lately, my MMI display has been acting up. It randomly freezes, restarts, or fails to turn on at all. What could be causing this and how can I fix it?
ReplyFirst and foremost, try resetting the MMI system by pressing and holding the SETUP button while starting the car. If this doesn't work, check the fuse and wiring for any issues. If those are fine, it could be a faulty control unit or display. I recommend taking it to a certified Audi technician for further diagnosis.
I've encountered this issue before and it turned out to be a software glitch. Try updating the MMI software through the Audi Connect Portal or bring it to a dealership for a software update. If that doesn't work, it could be a hardware issue as mentioned by the other answer.
Before taking it to the dealership, try disconnecting the battery for a few minutes and reconnecting it. This sometimes resets the system and resolves the issue. If not, it could be an issue with the screen itself and it may need to be replaced.
