What do I do if the touchscreen on my Audi A3 is not working?

I recently purchased an Audi A3 and the touchscreen seems to be unresponsive. I have tried restarting the car and checking the settings but it still doesn't work. What could be the issue?

Firstly, make sure that the car's software is up to date. If the issue persists, try resetting the infotainment system by holding down the power button for 30 seconds. If that doesn't work, you may need to bring it to a dealership for further troubleshooting.
