Cayenne TXV specification varies by refrigerant type (R134A vs R1234yf) and hybrid\/non-hybrid configuration — this part is for R134A non-hybrid variants only. Confirm fitment against your VIN and option codes before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe expansion valve meters liquid refrigerant flow into the evaporator core — the component that directly governs A\/C cooling output and cabin temperature response. A failed or degraded TXV presents as inconsistent A\/C output, compressor cycling at incorrect intervals, or complete A\/C loss. The Cayenne 9YA circuit runs at full demand under GCC conditions, exposing the valve to sustained high refrigerant mass flow and pressure differentials. Factory valve calibration — superheat setpoint and flow orifice geometry — is matched to the 9YA evaporator core dimensions and compressor displacement. Aftermarket valves frequently present calibration deviations that produce evaporator flooding, compressor liquid slugging, or insufficient cooling capacity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation Note\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eRequires full refrigerant recovery. Replace all disturbed O-rings with new factory seals. Verify evaporator core condition before installation. Recharge to Porsche-specified refrigerant weight and verify system pressures and superheat before returning to service.\u003c\/p\u003e","brand":"Porsche","offers":[{"title":"Default Title","offer_id":52221136830754,"sku":null,"price":550.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0944\/3957\/1746\/files\/066-20.webp?v=1786001394","url":"https:\/\/europarts360.com\/fr\/products\/porsche-cayenne-a-c-expansion-valve-txv-oem-pab82067900","provider":"Europarts360","version":"1.0","type":"link"}
