Denso 475-2075 A/C Expansion Valve

Denso New Expansion Valve for BMW A/C

Denso New Expansion Valve 475-2075 is a block valve A/C expansion valve built to regulate refrigerant flow through the evaporator and keep the low and high sides of the air conditioning system properly separated. For BMW owners dealing with weak cooling or unstable evaporator performance, this component supports accurate refrigerant metering in the HVAC system.

Compatible with select BMW 525i, 530i, 545i, 645Ci, 528i, 535i, 550i, 650i, M5, and M6 applications, this Denso 475-2075 expansion valve is a direct-fit service part for specific BMW A/C repairs.

Key Features

• Block valve style A/C expansion valve
• Regulates liquid refrigerant flow into the evaporator
• Helps maintain proper separation between suction and discharge sides
• Built for select BMW HVAC systems
• Denso New Expansion Valve line for OE-style service replacement

Product Details

The expansion valve is a critical control point in the air conditioning circuit. When calibration is off, the evaporator may not exchange heat correctly, which can reduce cooling performance or cause the evaporator to freeze. Denso engineers these A/C flow restrictor components with application-specific calibration in mind, helping restore proper refrigerant control in the vehicle HVAC system. Part number 475-2075 is listed for multiple BMW 5 Series, 6 Series, and M models, including 2004-2007 BMW 525i and 530i, 2006-2010 BMW 550i and 650i, and 2008-2010 BMW 528i and 535i.

This part cross-references Four Seasons 39222 for the same application.

What It Helps Address

• Weak or inconsistent cabin cooling
• Evaporator icing or freeze-up
• Improper refrigerant metering through the evaporator
• A/C performance loss caused by a worn or incorrect expansion valve
• HVAC service needs on BMW 525i, 530i, 535i, 550i, 645Ci, M5, and M6 models

Installation Notes and Tips

Verify the original valve style and OE part number before installation. Because expansion valves are calibration-sensitive, correct vehicle application matters for proper A/C operation. Inspect the system for contamination, leaks, and related wear before replacing the valve, and follow standard HVAC service procedures during reassembly and evacuation.

Quality Assurance

Denso draws on decades of A/C system engineering for automakers, and this New Expansion Valve line is built to meet the application-specific requirements of the vehicle HVAC system. Use the confirmed fitment list to match the correct BMW application before service.
