VW AC Expansion Valve - Vemo 5Q0820679B

Product Information

An A/C expansion valve's primary function is to regulate the flow of refrigerant into the evaporator, where it absorbs heat and cools the air inside the vehicle. The expansion valve reduces the pressure of the refrigerant, allowing it to expand and cool before it enters the evaporator coils. This process is essential for efficient cooling and overall performance of the A/C system.

• Poor Cooling Performance: One of the most common symptoms of a failing expansion valve is reduced cooling efficiency. The air coming from the vents may not be as cold as expected, even when the A/C system is running
• Frost or Ice Build-Up: If the expansion valve is stuck open, too much refrigerant may enter the evaporator, leading to excessive cooling and ice formation on the evaporator coils. This can cause airflow restrictions and further decrease cooling efficiency
