atment systems to monitor NOx emissions and control AdBlue dosing.

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

Q2: Where is it installed?
A2: It is installed in the SCR exhaust system, typically before or after the catalytic converter depending on engine layout.

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

Q4: Are these part numbers interchangeable?
A4: Yes, these OEM numbers are used across different Opel/Vauxhall SCR system revisions for the same NOx sensor function.
