Product overview

Genuine OEM Volkswagen A/C Expansion Valve, part number 4M0816679. This critical component is located within the air conditioning system, typically at the inlet of the evaporator. Its primary function is to regulate the flow of high-pressure liquid refrigerant, expanding it into a low-pressure gas as it enters the evaporator, which facilitates heat absorption from the cabin air.
