How do I reset the MMI system in an Audi A1?

I recently bought a used Audi A1 and the MMI system seems to be malfunctioning. How can I reset it to factory settings?

To reset the MMI system in an Audi A1, you need to press and hold the MENU and CAR buttons for about 5 seconds. This will bring up the MMI screen with the reset option. Just follow the instructions on the screen and your system will be reset to factory settings.

If the above method doesn't work, try disconnecting the car battery for 15-20 minutes and reconnecting it. This will also reset the MMI system. However, keep in mind that this may also reset other systems in your car, so it's best to do this only as a last resort.

You can also try doing a hard reset by holding down the NAV and SETUP buttons for about 10 seconds. This will completely wipe all settings and data from the system. Make sure you have any important data backed up before trying this method.
