How to enable auxiliary heating in a Audi A6?

I recently purchased a used Audi A6 and noticed that my car does not have auxiliary heating despite being advertised as a feature. How can I enable auxiliary heating in my car?

To enable auxiliary heating in your Audi A6, go to the settings menu on your car's dashboard. From there, navigate to the climate control section and look for the option to turn on auxiliary heating. If this option is not available, it is possible that your car does not have the necessary components for auxiliary heating.

I had a similar issue with my Audi A6 and was able to enable auxiliary heating by using a diagnostic tool to access the car's computer. This may be a more complicated and expensive solution, so try checking the settings first.
