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 (A10203L7AF) for VAG (VW/Audi/Seat/Skoda) 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 vehicle power supply and provides precise measurement signals to the engine control unit (ECU), ensuring that emission limits are maintained and error messages (e.g., NOx efficiency faults) are avoided. 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 at high exhaust temperatures. Installation is simple: remove the old sensor, disconnect the connector, insert the new sensor, and lock the plug; then clear the 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 specification of the listed references. Compatible with common Euro 6 diesel engines of the VAG (VW/Audi/Seat/Skoda) platform. Fast delivery and warranty included.
Compatible OE numbers: 03L 907 807 AF, 03L 907 807 AD, 8K0 907 807 C, 8K0 907 807 E, 265 9849.
