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

I accidentally made some changes in the MMI system and now it's not working properly. How can I reset it to its default settings? Will this affect any of the car's features?

To reset the MMI system, press and hold the MENU button for 10 seconds until the system restarts. This should solve any issues you're experiencing. However, please note that this will not affect any of the car's features, since the MMI system is a separate unit. If you're still experiencing issues after resetting, please consult your owner's manual or visit an authorized Audi dealership for further assistance.

Another way to reset the MMI system is by disconnecting the car battery for a few minutes. This will completely shut down the system and reset it to its default settings, but it may also reset some of your personal settings. If you're not comfortable doing this yourself, I would recommend taking it to an authorized Audi dealership.

I also faced a similar issue and found out that there are some hidden buttons on the MMI control panel, which can be used to reset the system. You can try pressing and holding the TONE and SETUP buttons for 10 seconds and then releasing them. This should trigger a system reset. If it doesn't work, try different combinations of buttons. If all else fails, take it to an authorized Audi dealership.
