How do I reset the Audi A6 Multimedia Interface (MMI)?

I am having issues with my MMI in my Audi A6 and I want to reset it. How can I do this on my own without having to take it to the dealership?

To reset the MMI in your Audi A6, first turn off the car and remove the key from the ignition. Then, disconnect the negative terminal of your car's battery and wait at least 15 minutes. Reconnect the battery and start the car. This should reset the system.

Another way to reset the MMI in your Audi A6 is to access the hidden menu on the MMI screen. Press and hold the CAR and SETUP buttons together for 6 seconds to access the menu. From there, you can select the option to reset the MMI.
