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

I accidentally changed some settings in the infotainment system of my Audi A4 and now it's not functioning properly. How can I reset it to its default settings?

To reset the infotainment system in an Audi A4, go to the main menu and select 'Settings'. Then, scroll down and select 'Factory reset'. This will reset all settings to their default values.

If the above method doesn't work, you can also try disconnecting the car battery for a couple of minutes. This will also reset the infotainment system.

Sometimes a software update can also cause issues with the infotainment system. Make sure your system is up to date by checking for any updates on the Audi website.
