A0009053403 / 5WK96681D Mercedes NOx Sensor for W212 W222 C218 X218 A207 (2011–2017).

Product Description:

The A0009053403 / 5WK96681D NOx Sensor is a genuine OEM part used in many Mercedes-Benz diesel vehicles from 2011 to 2017. This sensor plays a critical role in your vehicle’s Selective Catalytic Reduction (SCR) system by detecting nitrogen oxide (NOx) levels in the exhaust and sending the data to the engine control unit (ECU). The ECU then adjusts AdBlue injection to reduce emissions and ensure compliance with stringent EURO standards.

Built to OEM specifications, this sensor guarantees a perfect fit, reliable performance, and long-lasting durability. Replacing a malfunctioning NOx sensor can improve fuel efficiency, engine performance, and emissions compliance.
