Product Overview
This NOx sensor is a critical emissions control component for BMW vehicles equipped with Selective Catalytic Reduction (SCR) systems. It continuously monitors nitrogen oxide levels in exhaust gases, enabling precise urea (AdBlue/DEF) dosing to maintain compliance with Euro 5/6 and EPA Tier 2 Bin 5 emissions standards.
Key Features
- Wide-band lambda sensing with dual-chamber design
- Integrated control unit with CAN bus communication
- OEM-grade YSZ (Yttria-Stabilized Zirconia) ceramic element
- Self-diagnostic function with fault code storage
- Plug-and-play installation with factory connector

Important Notes
After installation, the engine control module (ECM) must perform a NOx sensor calibration cycle. This typically requires 10-15 minutes of mixed driving conditions. Some vehicles may require dealer-level diagnostic tool to clear adaptation values.
