Installed in the A/C system, positioned between the condenser and the evaporator.

What this product does:
• Controls refrigerant flow between the condenser and evaporator
• Maintains optimal pressure for consistent cabin cooling
• Prevents evaporator freeze-up and protects the A/C compressor

Expansion valves wear out over time, becoming clogged, sticky, or unresponsive. Symptoms include weak or inconsistent cooling, fluctuating cabin temperatures, or compressor strain. Replacing with a genuine Porsche 95557231901 valve restores proper cooling efficiency, ensures system longevity, and maintains comfort in your Cayenne.
