I would alos use RECIRC for the reasons you listed. However, the windows will not have condensation on them because the interior moisture will collect on the evaporator and exit the car via the drain. With dryer air in the interior, there is no moisture to plate onto the windshield/windows. That's why the A/C kicks in when you turn on the defroster to clear the windshield/windows.

I found it on the Audi website. It was UK related, but I could not see why it would not apply to US.

But if you set the Recirculate to "Auto" in MMI, you should never have to hit the button correct?

Click on the Air Conditioning tab. There is a video.

"To ensure your air-conditioning system is running at maximum efficiency we recommend that you have an air-conditioning service carried out every two years. Our Audi Trained Technicians will carry out a full drain and recharge of the gas in the system as well as a detailed inspection of hoses and connectors as well as the cooling fan and compressor drive belt."
