How can I reset the MMI system in an Audi A6?

I'm having trouble with the MMI system in my Audi A6 and it's not responding. How can I reset it so that it starts working again?

To reset the MMI system in your Audi A6, first try turning off the ignition and removing the key for a few minutes. If that doesn't work, you can perform a hard reset by pressing the top right button and the control knob on the MMI system simultaneously for 10 seconds.

If the MMI system is still not responding after a reset, it may be a faulty control unit. Consider taking your Audi A6 to an authorized dealership for further diagnosis and repair.

Another possible solution is to disconnect the car battery for a few minutes and then reconnect it. This can sometimes reset the MMI system and resolve any issues.
