FAQ

Q1: Are A0101539428 and 5WK96653C the same sensor?
A1: Yes. A0101539428 is the Mercedes-Benz OE number, and 5WK96653C is the sensor manufacturer reference used for the same NOx sensor module in SCR systems.

Q2: What vehicles use this sensor?
A2: It is commonly used on Mercedes-Benz heavy-duty trucks such as Actros, Arocs, and Antos equipped with Euro 6 SCR (AdBlue) emissions systems.

Q3: Is this inlet or outlet sensor?
A3: It is typically used as a downstream (post-catalyst / SCR outlet) NOx sensor in heavy-duty diesel aftertreatment systems.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) in exhaust gases and sends data to the ECU, which controls AdBlue dosing to reduce emissions and ensure SCR system efficiency.
