Your Audi A/C system has a number of components working together to provide a cool and comfortable atmosphere. One such component is the Expansion device. The Audi A/C Expansion device regulates the flow of gas inside the Air Conditioning system. The primary function of the Expansion device is to allow the correct amount of refrigerant according to your cooling requirements. If you turn up your Air Conditioning, the Expansion device expands to release refrigerant through the system and when you turn it down, it shrinks and slows down the refrigerant flow.
An Expansion device opens and closes to keep the Evaporator core temperature from freezing. If you find any difference in the working of the A/C system, you need to check the issue as soon as possible. If you do not, it will affect the performance of the Air Conditioning system.
