FAQ

Q1: Are A0009053009, SNS381B, and 5WK97424 the same sensor?
A1: Yes. A0009053009 is the Mercedes-Benz OE number, SNS381B is the sensor family code, and 5WK97424 is the Continental/VDO 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 diesel models such as C-Class (W205), E-Class (W212/W213), CLS, GLC, GLE, and Sprinter vehicles equipped with Euro 6 SCR (AdBlue) systems.

Q3: Is this inlet or outlet sensor?
A3: It is typically used as a post-catalyst (downstream) NOx sensor in SCR systems, but exact placement depends on engine and exhaust configuration.

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