To reset the MMI infotainment system in your Audi A4, you will need to press and hold the power button, the Radio button, and the TONE button simultaneously for about 10 seconds. This should reset the system back to its factory settings.

If the above method does not work, you can also reset the MMI system by disconnecting the car battery for a few minutes and then reconnecting it. This should also reset the system.
