Built to OEM specification and matching part numbers A0009052809, A2C16442600-291, A0009058511, A3C01067600-609 and A0009059703.\u003c\/p\u003e\n\u003ch3\u003eCommon signs of failure\u003c\/h3\u003e\n\u003cp\u003eA failing NOx sensor on diesel vehicles typically triggers fault codes P220A, P220B, P220C, P229F or P207F (NOx sensor circuit \/ SCR system efficiency). Drivers see the engine warning light come on, an AdBlue or 'Emissions' warning on the dashboard, often a countdown 'Vehicle will not start in X miles' message, and in many cases the vehicle entering limp mode. Left unaddressed, the ECU will eventually prevent the engine from restarting until the fault is cleared.\u003c\/p\u003e\n\u003ch3\u003eFitment notes\u003c\/h3\u003e\n\u003cp\u003eDirect-fit replacement, with the original wiring harness and ECU connector. After fitting, the sensor needs a short re-learn drive cycle (typically 5–20 minutes of motorway driving) for the ECU to calibrate to the new probe. Some manufacturers recommend resetting adaptations with a diagnostic tool — useful but not strictly required on most models. Standard 5 pin connector.\u003c\/p\u003e\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\u003ch4\u003eWhere is the NOx sensor located?\u003c\/h4\u003e\n\u003cp\u003eMost diesel vehicles have two NOx sensors: one upstream and one downstream of the SCR catalyst\/AdBlue injection point. Identify whether your fault is for the inlet or outlet sensor (the code and live data will tell you) before ordering.\u003c\/p\u003e\n\u003ch4\u003eWill it fix my limp-mode and AdBlue warning?\u003c\/h4\u003e\n\u003cp\u003eYes, if the fault code points to the NOx sensor itself. After fitting, clear the codes and complete a regen drive cycle — warnings usually clear within a few miles.\u003c\/p\u003e\n\u003ch4\u003eHow long do NOx sensors last?\u003c\/h4\u003e\n\u003cp\u003eTypically 80,000–120,000 miles, though heavy stop-start driving and poor-quality AdBlue can shorten lifespan. Replacement at the first sign of failure prevents the vehicle locking you out.\u003c\/p\u003e","brand":"PitShopUK","offers":[{"title":"Default Title","offer_id":57283901555032,"sku":"197","price":145.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0947\/3373\/0136\/files\/SKU197_A0009058411-6_updated_78b1b2bb-b799-4e12-a3ba-5b5cc684618e.jpg?v=1781011498","url":"https:\/\/carpartclubs.com\/products\/nox-sensor-for-mercedes-benz-a0009058411-a0009059603-a0009050008-a0009052709","provider":"CarPartClubs","version":"1.0","type":"link"}
