Detailed Description

Global Parts 3412063 is built for HVAC flow control in the A/C system, where refrigerant must be metered before entering the evaporator. By regulating that flow, the valve helps the evaporator operate within the correct pressure and temperature range for consistent cabin cooling. This part number 3412063 is used on front-position BMW applications including 2022-2026 BMW 230i, 2023-2026 BMW 230i xDrive, 2024-2026 BMW 430i, 2021 BMW 430i, 2023-2026 BMW 430i Gran Coupe, 2023-2026 BMW 430i xDrive Gran Coupe, 2024-2026 BMW M4, 2026 BMW M440i, 2024 BMW M440i, 2022-2026 BMW M440i Gran Coupe, 2021-2026 BMW M440i xDrive, 2022-2026 BMW M440i xDrive Gran Coupe, 2024-2026 BMW Z4, 2024-2025 BMW 330i, 2024-2025 BMW 330i xDrive, 2024-2025 BMW 430i xDrive, 2021 BMW 430i xDrive, 2023-2025 BMW M2, 2023-2025 BMW M240i, 2022-2025 BMW M240i xDrive, 2023-2025 BMW M3, 2024-2025 BMW M340i, 2024-2025 BMW M340i xDrive, 2024-2025 BMW X4, and 2024 BMW X3. It also covers N/A-position BMW 330i, 330i xDrive, M340i, M340i xDrive, M440i, X3, X4, Z4, 430i, 430i Gran Coupe, 430i xDrive, M3, and M4 applications listed in the fitment data.

What It Can Help Resolve

• Weak or uneven cabin cooling
• Incorrect refrigerant metering at the evaporator
• A/C performance loss after system service
• Restricted refrigerant flow in the front HVAC circuit
• Expansion valve wear found during BMW A/C repair

Installation Notes and Tips

Replace the expansion valve during A/C system service when the circuit is opened, and verify the correct BMW application by year, model, and position before installation. Proper evacuation, recharge, and leak checking are required after service. This part number 3412063 is commonly searched for BMW 230i expansion valve, BMW 330i A/C expansion valve, and BMW M440i front HVAC repair.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced. This part cross-references Four Seasons 39647 and UAC EX10717C for the same application.
