How to fix a malfunctioning touchscreen in an Audi?

The touchscreen in my Audi has been acting up, sometimes it doesn't respond to touch and other times it freezes. How can I fix this issue?

First, try restarting your car's infotainment system by pressing and holding the power button for 10 seconds. If that doesn't work, try calibrating the touchscreen by going to the settings menu and following the instructions for touchscreen calibration.

If the issue persists, it could be a hardware problem. You may need to take your Audi to a mechanic or dealership for further diagnosis and potential repair. Be sure to check your car's warranty to see if this issue is covered.
