How to troubleshoot a non-responsive touchscreen on an Audi A2?

I recently purchased an Audi A2, but the touchscreen display seems to be non-responsive. How can I troubleshoot and fix this issue?

First, try restarting the system by holding the power button for 10 seconds. If that doesn't work, check the cable connections between the display and the main unit. Make sure they are securely connected and not damaged. Sometimes dust or debris can accumulate and cause connection issues. If the problem persists, it may be a hardware issue and you may need to consult a professional or contact Audi customer support.

You can also try resetting the system by disconnecting the car battery for a few minutes and then reconnecting. This can sometimes fix touchscreen issues. If not, you may need to update the software on your Audi A2. Check the Audi website for any available updates and follow the instructions carefully.
