The Audi A/C Expansion device is one of the vital component in the A/C system which helps regulate the flow of refrigerant inside the system. It controls the amount of refrigerant according to what temperature you want it to be inside your car. The amount of liquid refrigerant entering the evaporator must be equal to the amount of refrigerant boils in the Evaporator coils. When you increase the cooling demand the Expansion device expands to release more amount of refrigerant and when you decrease the cooling level, it slows down the flow of refrigerant.
