Your Audi A/C system involves a Compressor, Condenser, Evaporator, and Expansion device. Expansion device is a major component which regulates the flow of refrigerant based on the preferred temperature set by the driver. When that temperature is cooler, the Audi A/C Expansion device expands its valve to allow more refrigerant to flow into the system and it shrinks when the desired temperature is hotter.
If the Audi S5 A/C Expansion device is damaged, it will also affect other parts in the vehicle, so it must be replaced as soon as possible.
