Detailed Product Information

This Global Parts 3412016 expansion valve is used in the refrigerant circuit to reduce pressure and control flow before the evaporator. That metering action helps the A/C system use refrigerant more effectively, which is important when servicing Audi climate control systems. It is a direct-fit service part for a wide range of Audi platforms, including 2017-2023 Audi A4 allroad, 2017-2023 Audi A4 Quattro, 2018-2022 Audi A5 Sportback, 2019-2022 Audi A6 Quattro, 2019-2022 Audi A7 Sportback, 2018-2022 Audi Q5, and 2022-2023 Audi Q7. The part number 3412016 is also listed for additional Audi applications such as A8 Quattro front, Q8 front, and e-tron models.

What It Helps Address

• Weak or uneven A/C cooling
• Incorrect refrigerant metering at the evaporator
• Reduced evaporator efficiency after A/C service
• Climate control performance issues on Audi A4, A5, Q5, and Q7 models

Installation Notes and Tips

Verify the vehicle’s exact year, model, and position before ordering. This listing includes N/A and Front applications, so match the original part location to the fitment table. During A/C service, inspect the system for contamination and replace the expansion valve/orifice tube when the system is opened, as recommended by the manufacturer. Proper evacuation, recharge, and leak checking are required after installation.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced to help maintain proper refrigerant control and evaporator performance.
