The Air Conditioning system is an essential component in your Audi. It has many components such as a Compressor, Condenser, Expansion device and many more parts. The main function of the Expansion device is to regulate the flow of gas inside the A/C system. According to how cool you want your car, the flow of refrigerant differs. The Audi Expansion device releases more refrigerant when you want it cooler and less refrigerant when you don’t want it as cold.
The Expansion device allows liquid to pass through an orifice tube by sensing the temperature of the Evaporator. 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.
