How to troubleshoot a non-responsive infotainment screen in an Audi A3?

My Audi A3's infotainment screen is not responding to touch or button inputs. How can I fix this issue?

Firstly, try restarting your infotainment system by holding down the power button for 5 seconds. If this does not work, check for any loose connections in the wiring or fuses. You can also try resetting the infotainment system by disconnecting the battery for a few minutes and then reconnecting it.

If the issue persists, it could be a software glitch. Try updating the infotainment system software to the latest version. You can do this by connecting your Audi to a Wi-Fi network and going to the settings menu.

Alternatively, you can try a factory reset of the infotainment system. This will erase all personalized settings and data, so make sure to back up anything important before proceeding.
