The NOx sensor is a central component of exhaust aftertreatment. It consists of
a probe and a control unit, is integrated into the exhaust system as a complete unit,
and detects nitrogen oxides (NOx) in the exhaust flow. Its use ensures compliance
with strict emission standards such as Euro 5 and Euro 6.
Note: Due to the high technical complexity and the required measurement accuracy,
the use of replacement parts in OE quality is recommended.
ORIGINAL Ampro Mercedes Benz NOx Sensor A0009052519 W906 W447 W253 NEW
High-performance Ampro NOx sensor (A1038411) for Mercedes-Benz commercial vehicles.
Measures nitrogen oxides in the exhaust line and supports precise control of the SCR (AdBlue) catalyst to meet Euro VI limits.
Designed for 12 V electrical systems, it delivers accurate signals to the ECU and stabilizes exhaust aftertreatment.
OE-grade build with vibration-resistant housing, heat-resistant electronics, and corrosion-protected connectors—ideal for demanding fleet use.
Exact fit for the listed references; a reliable aftermarket replacement with long-lasting calibration.
Installation: remove the old unit, unplug the connector, screw in and lock the new sensor; then clear fault codes and perform a short adaptation drive.
Delivered with a pre-terminated wiring harness.
Compatible OE/reference numbers (MB): A 000 905 84 11, A 000 905 27 09, A 000 905 00 08, A 000 905 96 03, A 000 905 25 19.
