Expansion Valve

WARNING: This page does not describe the selected car, but rather 33 other vehicles, including the 2010 BMW M5, 2009 BMW M5, 2008 BMW M5, 2008 BMW 760Li, and 2007 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.

The expansion valve is directly on the evaporator in the heating/air-conditioning system. The valve regulates the injection rate in the evaporator. Only as much liquid refrigerant is permitted to enter the evaporator as the evaporator is able to completely evaporate. Drops of liquid that have not been evaporated could cause damage in the A/C compressor.
