FAQ

Q1: Are A0111536228 and SNS3043 the same sensor?
A1: Yes. A0111536228 is the Mercedes-Benz OE number, and SNS3043 / 5WK97210 are matching NOx sensor references used in the same SCR system.

Q2: What vehicles use this sensor?
A2: It is commonly used on Mercedes-Benz heavy-duty trucks such as Actros, Antos, Arocs, Atego, and Econic equipped with Euro 5 / Euro 6 SCR (AdBlue) emissions systems.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either upstream or downstream NOx sensor depending on exhaust configuration in the SCR system.

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