I've been having some trouble with my MMI system in my Audi A4. Sometimes the screen freezes or it doesn't respond to my touch. How can I fix this issue?
ReplyFirst, try restarting the system by pressing and holding the power button for 10 seconds. If that doesn't work, check if there are any software updates available for your MMI system. If there are, make sure to install them to see if that resolves the issue.
If updating the software doesn't help, you can try resetting the MMI unit by disconnecting the car battery for a few minutes. Just be sure to have your radio code handy as you will need to re-enter it after the reset.
If all else fails, it may be an issue with the hardware. In this case, it's best to take your Audi to a certified technician who can properly diagnose and fix the problem.
