How to fix a non-functioning touch screen in Audi cars?

The touch screen in my Audi car has suddenly stopped working. How can I troubleshoot and fix this issue on my own?

First, try restarting the car's infotainment system by pressing and holding the power button for 10 seconds. If that doesn't work, check for any software updates for the touch screen. If there aren't any updates available, you may need to reset the system to its factory settings. This can usually be done through the settings menu. If all else fails, it may be a hardware issue and you should take your car to a certified Audi technician for repair.

Make sure your hands are clean and free of any lotion or oils before using the touch screen. Sometimes, residue on your fingertips can interfere with the touch sensitivity. You can also try adjusting the touch screen sensitivity settings in the car's menu. If the issue persists, it's best to have a professional inspect and repair the touch screen.

I had a similar issue with my Audi and found that the problem was with the touch screen protector film that I had applied. When I removed it, the touch screen started working again. Make sure you don't have any films or screen protectors that could be hindering the touch sensitivity.
