The Expansion device is one of the major components in your Audi A/C system. The Expansion valve regulates the flow of gas inside the A/C system and it controls the flow of refrigerant according to how cool you want it to get inside your car. You have the ability to control the temperature of your Audi A/C system. If you crank up the A/C system, the Expansion valve expands and releases more refrigerant through the system. If you turn the A/C System down, the Expansion valve shrinks which decreases the amount of refrigerant.
If the Audi A/C Expansion device does not work properly, you will feel the difference in the usual cooling effect of your Air Conditioning.
