FAQ

Q1: Are A0111531728 and SNS744 the same sensor?
A1: Yes. A0111531728 is the Mercedes-Benz OE number, while SNS744 is a Continental/Vitesco reference used for the same NOx sensor module in SCR systems.

Q2: What vehicles use this sensor?
A2: It is mainly used on Mercedes-Benz Actros, Antos, and Arocs trucks, as well as Freightliner Cascadia models equipped with Detroit DD13/DD15/DD16 engines using SCR (AdBlue) emissions systems.

Q3: Is this inlet or outlet sensor?
A3: It is most commonly used as a post-SCR (outlet) NOx sensor, but exact placement depends on the exhaust layout and OEM configuration.

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