Mercedes-Benz NOx Sensor A0009054704 / 5WK97381 / A2C95270000-01 for W213 E-Class & W222 S-Class.

Product Description

Genuine specification NOx Sensor (Nitrogen Oxide Sensor) for modern Mercedes-Benz diesel vehicles.
OEM part numbers: A0009054704, 5WK97381, A2C95270000-01.

This sensor measures NOx levels in the exhaust and communicates with the SCR/AdBlue system to ensure correct dosing, emissions control, and optimal engine efficiency.
A failing NOx sensor can trigger AdBlue warnings, reduced power, limp mode, increased fuel consumption, and emission faults. This replacement restores proper system operation.
