How to fix the touch screen in my Audi A7?

The touch screen in my Audi A7 has stopped working. It doesn't respond to touch at all, making it difficult to use the navigation system or adjust any settings. What could be causing this issue and how can it be fixed?

It's possible that the touch screen is simply dirty and needs to be cleaned. Try using a microfiber cloth and some screen cleaner to see if that improves its responsiveness.

If cleaning the screen doesn't work, it may be a software issue. Try resetting the infotainment system by holding down the power button for 10 seconds.

If neither of these solutions work, it could be a hardware problem. In that case, it's best to take your Audi A7 to a certified dealership or mechanic for further diagnosis and repair.
