URO 6N0820679C A/C Expansion Valve

OE-Style A/C Expansion Valve

This URO A/C expansion valve restores refrigerant metering in the air conditioning system when the original valve fails or becomes restricted. Built to OE valve dimensions and made from 4043 aluminum, part number 6N0820679C is a direct-fit service replacement for select Volkswagen and Audi applications.

Compatible with 1992-2010 Volkswagen and Audi HVAC systems, including Volkswagen Beetle, Golf, Jetta, Cabrio, Passat, Corrado, and Audi TT/TT Quattro applications. The externally equalized block design helps maintain proper refrigerant flow across a wide range of operating temperatures and pressures.

• 4043 aluminum construction for HVAC service durability
• Externally equalized, block-style valve design
• Manufactured to OE valve dimensions for clearance and installation fit
• Restores proper A/C system refrigerant control after valve failure
• Built for extreme refrigerant pressure and temperature variation
• URO part number 6N0820679C for direct replacement lookup

Detailed Product Information

The expansion valve regulates refrigerant entering the evaporator, which directly affects vent temperature and system performance. When the valve sticks, clogs, or loses control of flow, the A/C system can deliver weak cooling, uneven outlet temperatures, or abnormal pressure behavior. This replacement valve is engineered to match OE dimensions and service requirements for Volkswagen Beetle, Golf, Jetta, Passat, Corrado, Cabrio, and Audi TT/TT Quattro models listed in the fitment data. This part cross-references VEMO V15-77-0004 for the same application.

Common A/C Problems This Part Can Address

• Warm air from the vents during A/C operation
• Erratic cabin cooling or inconsistent vent temperatures
• Restricted refrigerant flow through the evaporator circuit
• Pressure imbalance caused by a worn or stuck expansion valve
• Poor system performance after A/C service or component replacement

Installation Notes and Tips

Replace the expansion valve during A/C system service when the original unit has failed or contamination is present. Verify the system is properly evacuated, inspect the evaporator and lines for debris, and confirm the valve orientation matches the OE block-style layout before reassembly. For best results, follow the vehicle service procedure for the specific Volkswagen or Audi model and year.

Quality Assurance

URO backs this part with a 24 month unlimited mileage warranty. The valve is manufactured from high-quality materials and built to meet OE fitment expectations for the listed applications.
