What is the best way to troubleshoot the MMI touch response issue in my Audi A6?

I have encountered an issue where the touch response on my Audi A6's Multi Media Interface (MMI) is not working properly. I have tried restarting the system and adjusting the settings, but the problem persists. Has anyone experienced and solved this issue before?

In most cases, this issue can be resolved by performing a system reset. Hold down the power button for at least 10 seconds until the system shuts down, then turn it back on. If that doesn't work, there may be a hardware issue and you should consult with a certified technician.

One potential solution is to check for any software updates and install them if necessary. It's also a good idea to make sure your screen is clean and free of any debris that may be affecting the touch response.

I had a similar issue and found that resetting the car battery helped resolve it. This is not a guaranteed fix, but could be worth a try before taking it to the dealership.
