Product Details

Four Seasons 39399 is an A/C expansion valve used to regulate refrigerant flow into the evaporator on BMW HVAC systems. The block-type design, captured O-ring sealing surfaces, and OE-matching connection sizes support accurate refrigerant metering in R134A-equipped vehicles. This part number 39399 cross-references UAC EX10304C for the same application.

Compatible BMW applications include 2006-2011 BMW 323i, 2006 BMW 325xi, 2006 BMW 330xi, 2007-2013 BMW 328i, 2007-2013 BMW 335i, 2008-2013 BMW 128i, 2008-2013 BMW 135i, 2008-2013 BMW M3, 2009-2013 BMW 328i xDrive, 2009-2013 BMW 335i xDrive, 2011-2013 BMW 335is, 2011 BMW 1 Series M, 2011-2015 BMW X3, 2012-2015 BMW X1, 2015 BMW X4, and 2016 BMW X3/X4/X5 to 4/16.

Common A/C Issues This Part Addresses

  • Incorrect refrigerant metering at the evaporator
  • Weak or inconsistent cabin cooling
  • Expansion valve leakage at the O-ring seals
  • Restricted A/C flow caused by a worn internal valve
  • HVAC performance loss on BMW R134A systems

Installation Notes

Verify refrigerant type, connection style, and OE part match before installation. This valve uses female suction and liquid fittings with captured O-ring sealing surfaces, so inspect the mating surfaces and replace damaged seals as needed during service. Confirm the vehicle application by model year, since some 2016 BMW X3, X4, and X5 listings apply only to vehicles built to 4/16.

Quality Assurance

Four Seasons lists this expansion valve as meeting or exceeding OEM specifications for the application. The aluminum construction and OE-style fitment support consistent service replacement on BMW HVAC systems. Part number 39399 is cataloged for direct replacement use in the listed BMW models.
