How do I troubleshoot the MMI system on my Audi?

I'm facing issues with connecting my phone to the MMI system in my Audi. It was working fine yesterday but now it won't connect. The Bluetooth keeps turning off when I try to connect. What could be the problem and how do I fix it?

First, try resetting your MMI system by pressing the Menu, Back, and Top Right buttons at the same time. If that doesn't work, make sure your phone is compatible with the MMI system and check if there are any software updates available for your Audi.

Another possibility is that there may be interference from other devices in the car. Try turning off other Bluetooth devices and see if that helps. If not, you may need to reset the Bluetooth connection settings in your MMI system.
