FITMENT
Compatible with Mercedes-Benz heavy-duty diesel vehicles equipped with SCR (Selective Catalytic Reduction) AdBlue emission systems requiring NOx monitoring.
Common applications include:

• Mercedes-Benz Actros (Euro 6 variants)
• Mercedes-Benz Arocs
• Mercedes-Benz Antos
• Select Mercedes-Benz commercial trucks and bus platforms with SCR systems
  Using reference numbers:
• A0111536428

This NOx sensor is used in SCR exhaust aftertreatment systems to monitor emissions and control AdBlue dosing for compliance.

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 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 configuration.

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: Is SNS3045 compatible with SNS3044 or SNS3042?
A4: They belong to the same Mercedes SCR NOx sensor family, but compatibility depends on engine version and ECU calibration.
