Detailed Description

Universal Air EX10304C is an A/C expansion valve used in BMW HVAC systems to regulate refrigerant flow through the evaporator circuit. This block-style valve is listed for applications including 2011-2017 BMW X3, 2015-2016 BMW X4, 2013-2015 BMW X1, and multiple BMW 128i, 135i, 328i, 335i, M3, M5, and M6 models. If you are searching for a BMW A/C expansion valve, BMW block expansion valve, or EX10304C replacement for a specific chassis, this part number helps narrow the correct service match.

The Universal Air Block Expansion Valve line focuses on this specific HVAC control component rather than a broad accessory range. For BMW owners and technicians, EX10304C is a catalog-ready reference when replacing a faulty A/C flow restrictor on supported vehicles.

Common Problems This Part Can Address

  • Weak or inconsistent cabin cooling
  • Improper refrigerant metering at the evaporator
  • A/C performance loss on BMW HVAC systems
  • Temperature fluctuations from a worn expansion valve
  • Service replacement for a leaking or restricted block valve

Installation Notes and Tips

Verify the vehicle’s exact year, model, and HVAC configuration before ordering. Confirm the existing valve style matches a block expansion valve application, and compare the original part number EX10304C when available. Because this is an HVAC refrigerant control component, proper evacuation, recovery, and recharge procedures should be followed during installation.

Quality Assurance
