FAQ

Q1: Are A0111537328 and SNS1025 the same sensor?
A1: Yes. A0111537328 is the Mercedes-Benz OE number, and SNS1025 is the sensor family 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 commercial and heavy-duty vehicles such as Actros, Arocs, Atego, and Unimog 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 systems, but exact placement depends on exhaust configuration.

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