FITMENT
Compatible with Volkswagen diesel vehicles equipped with SCR (Selective Catalytic Reduction) AdBlue emission systems requiring NOx monitoring.
Common applications include Euro 6 diesel platforms using reference:

  • 5WK97442A
  • SNS442A
  • A2C38402100-04

Typically used in VW Group diesel aftertreatment systems.

FAQ
Q1: What is the function of this NOx sensor?
A1: It measures nitrogen oxide (NOx) levels in the exhaust system and sends real-time data to the ECU to control AdBlue/DEF injection and reduce emissions.

Q2: Where is it installed?
A2: It is installed in the exhaust system, usually before or after the SCR catalytic converter depending on vehicle configuration.

Q3: What are symptoms of failure?
A3: Check engine light, SCR/AdBlue system warnings, NOx sensor fault codes, reduced engine performance, or limp mode activation.

Q4: Is it compatible with all Volkswagen models?
A4: No, compatibility depends on engine type (TDI variants), model year, and SCR system setup.
