Diagram Ref No 20

The expansion valve is a critical component within the air conditioning system, controlling refrigerant pressure and volume as it enters the evaporator. Over time, contamination, internal wear, corrosion, or blockage can cause the valve to malfunction, resulting in poor cooling performance, fluctuating vent temperatures, or increased strain on the compressor. This OE Match replacement restores correct refrigerant flow and helps return the air conditioning system to reliable, efficient operation.  

What This Product Does:

• Regulates refrigerant flow into the evaporator.
• Controls refrigerant pressure for efficient cooling.
• Maintains consistent air conditioning performance.
• Helps prevent evaporator freezing.
• Protects the air conditioning compressor from excessive system load.
• Restores OE-style refrigerant control.
• Replaces worn, blocked, or faulty original expansion valves.

Symptoms Of Wear Or Failure:

• Weak or insufficient air conditioning cooling.
• Fluctuating vent temperatures.
• Air conditioning system freezing or icing.
• Compressor cycling excessively.
• Poor refrigerant flow through the system.
• Reduced air conditioning efficiency.
• Internal blockage caused by contamination.
• Refrigerant leaks around the valve.
• Increased compressor load or unusual operating behaviour.

Why Replacement Matters:

• The air conditioning expansion valve is essential for maintaining the correct refrigerant flow and pressure throughout the air conditioning system. A faulty or restricted valve can significantly reduce cooling performance, increase compressor wear, and lead to inefficient system operation.
• Replacing a worn expansion valve restores efficient refrigerant control, improves cooling performance, and helps protect expensive air conditioning components from premature failure. Manufactured to OE-style specifications, this OE Match replacement provides the correct fit, dependable operation, and long-lasting durability, making it an essential component for maintaining your Porsche's climate control system.
