Why does my Audi A6's start-stop function not activate?

I noticed that the start-stop function on my Audi A6 is not working, even though it is enabled in the settings. Is there a specific requirement for it to work properly?

The start-stop function may not activate if your car battery is not fully charged. It is recommended to regularly check your battery's health and replace it when necessary.

Another potential reason for the start-stop function not activating could be a fault in the electrical system. It is recommended to have your car inspected by a certified mechanic to diagnose and fix any potential issues.
