How do I reset the MMI system in an Audi A4?

The MMI (Multi Media Interface) system in the Audi A4 controls various functions such as radio, navigation, and vehicle settings. However, sometimes it can become unresponsive or glitchy and require a reset. How can I do this?

To reset the MMI system in an Audi A4, simply press and hold the rotary knob (located to the right of the screen) and the upper right button at the same time. Hold for about 10 seconds until the MMI system restarts. This can help resolve any software issues that may be causing glitches or unresponsiveness.
