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.

This high-quality NOx sensor (A1031412) for Mercedes-Benz monitors nitrogen oxide levels in the exhaust system and works together with the SCR catalytic converter (AdBlue) to regulate emissions in compliance with the Euro 6 standard.
It operates reliably with a 12 V power supply and provides precise measurement signals to the engine control unit (ECU), ensuring emission limits are maintained and preventing error messages (e.g., NOx efficiency faults). Manufactured in OE quality: robust sensor design with an integrated control unit, heat-resistant electronics, and corrosion-proof connectors ensure a long service life even under high exhaust temperatures. Installation is straightforward: remove the old sensor, disconnect the connector, insert the new sensor, and lock the plug; then clear fault codes and perform a short test drive. Technical notes: vehicle-specific connector, preassembled wiring harness; cable length and pin configuration correspond to the OE specifications of the listed references. Compatible with common Euro 6 diesel engines on the Mercedes-Benz platform. Fast delivery and warranty included.
Compatible OE numbers: A 000 905 14 12, A 000 905 35 06, A 000 905 50 06, 1793379, 1836060, 2011649.

A strong ammonia smell from the exhaust (often described as a sharp “AdBlue®/DEF smell”) is a warning sign that something is wrong in the SCR exhaust aftertreatment system. In Euro...
