How do I reset the MMI system in an Audi A2?

I recently purchased a used Audi A2 and noticed that the multimedia interface (MMI) system is not functioning properly. How can I reset the system to resolve any potential glitches or issues?

To reset the MMI system on your Audi A2, press and hold down the MENU, center control knob, and top right control button at the same time for 10 seconds. This will restart the system and clear any temporary malfunctions.

If the MMI system is completely unresponsive, you can reset it by disconnecting the car battery for a few minutes and then reconnecting it. This will reboot the system and may solve any issues.

Performing a factory reset on the MMI system should only be done as a last resort, as it will erase all saved settings and data. To do this, go to the SETUP menu, select SYSTEM, and choose FACTORY SETTINGS.
