Detailed Product Information

This expansion valve is used in the HVAC refrigerant circuit to meter refrigerant before it enters the evaporator. That metering action helps the system deliver consistent cooling performance when the rest of the A/C components are in good condition. Part number 3411445 is listed for a wide range of BMW and Mini vehicles, including BMW 323i, 325Ci, 330i, M3, X3, and Mini Cooper Countryman and Paceman applications.

Common A/C Problems It Can Address

• Weak cabin cooling from incorrect refrigerant metering
• Erratic vent temperatures during A/C operation
• Restricted refrigerant flow at the evaporator inlet
• Service-related wear in the expansion valve/orifice tube
• Reduced A/C efficiency after system maintenance

Installation Notes and Tips

Replace the expansion valve during A/C service when the system is opened for repair. Verify the vehicle’s exact year, make, and model before ordering, since fitment varies across BMW and Mini platforms. For best results, inspect the refrigerant circuit for contamination, leaks, and related wear before reassembly.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced. This part number 3411445 is listed with multiple interchange references, including DENSO Auto Parts 475-2079 and Four Seasons 39035, for the same application family.
