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

Q2: Where is it installed?
A2: It is installed in the SCR exhaust system, usually before or after the catalytic converter depending on engine 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 A2C95362100-01 the same as 5WK9 7319?
A4: Yes, A2C95362100-01 is the OEM/reference number and 5WK9 7319 is the manufacturer cross-reference for the same NOx sensor unit.
