FAQ

Q1: Are SNS708 and 4M0907807J the same sensor?
A1: Yes. SNS708 is the Continental/VDO reference, and 4M0907807J is the Volkswagen/Audi-style OE cross number used in shared SCR sensor platforms.

Q2: What vehicles use this sensor?
A2: It is mainly used on Mercedes-Benz GLE, GLS, ML and other diesel models with Euro 6 SCR (AdBlue) systems depending on engine and exhaust layout.

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

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