The Expansion device is one of the major components in your BMW A/C system. It regulates the flow of gas inside the A/C system and it allows the flow of refrigerant. You can change the cooling level in your car A/C system. According to your needs, the car A/C system will act accordingly. If you want the A/C system to get colder, the Expansion valve expands and releases the refrigerant through the system. If you decrease the cooling level, the expansion valve shrinks and slows down the release level.
