FAQ

Q1: Are A0101539428 and 5WK96363 related?
A1: They are commonly cross-referenced in the same Mercedes NOx sensor family. 5WK96363 is a sensor manufacturer code used for the same NOx sensor platform linked with A0101539428-type applications.

Q2: What vehicles use this sensor?
A2: It is used on Mercedes-Benz diesel models with SCR (AdBlue) systems such as C-Class (W205), E-Class (W212/W213), GLC, and GLE depending on engine version and exhaust configuration.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either inlet or outlet NOx sensor depending on exhaust layout. Mercedes often uses similar sensor modules in multiple positions.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) levels in the exhaust gas and sends data to the ECU to control AdBlue dosing, ensuring emissions compliance and SCR efficiency.
