NOx Sensor 4M0907807G Nitrogen oxide Sensor 3.0 TDI V6 Euro 6

Regular price €13995 EUR

New

NOx Sensor – Essential for Modern Emission Control

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.

Areas of Application

  • Modern diesel vehicles with exhaust aftertreatment (e.g., SCR, LNT)
  • On-board monitoring and regulation of emissions

Operating Principle

  • Operation at high exhaust temperatures
  • Dual-chamber principle: NOx is catalytically split, and the resulting oxygen is measured
  • Signal transmission via CAN bus to the Engine Control Unit (ECU)

Technical Highlights

  • High-precision NOx detection under real driving conditions
  • Fast response time during dynamic load changes
  • Robust design for continuous operation at high temperatures
  • Integrated control unit for signal conditioning and diagnostics

Benefits

  • Reliable compliance with Euro 5/Euro 6 limits
  • Optimized exhaust aftertreatment (e.g., AdBlue dosing)
  • Reduced emissions and improved efficiency
  • High measurement accuracy ⇒ reduced need for recalibration
  • Quality replacement available in OE specification

Interfaces & Communication

  • CAN bus for data transmission to the ECU
  • OBD-capable status and error messages

Installation Instructions

  • Mount directly in the exhaust tract according to manufacturer specifications
  • Position thermally correct (observe heat protection)
  • Electrical connection to ECU/CAN network; check tightness and cable routing

Scope of Delivery

  • NOx probe with integrated control unit
  • Mounting hardware (model-dependent)
  • Installation and safety instructions


Note: Due to the high technical complexity and the required measurement accuracy,
the use of replacement parts in OE quality is recommended.
