FAQ

Q1: Are A0065427218 and 5WK96677 the same sensor?
A1: Yes. A0065427218 is the Mercedes-Benz OE number, and 5WK96677 is the sensor reference used for the same NOx sensor module in SCR systems.

Q2: What vehicles use this sensor?
A2: It is commonly used on Mercedes diesel vehicles such as E-Class (W211/W212), ML/GL/GLE, Sprinter (906), and Vito/V-Class models equipped with SCR (AdBlue) emissions systems.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either upstream (inlet) or downstream (outlet) NOx sensor depending on exhaust system configuration. Many Mercedes SCR systems use similar sensor units in multiple positions.

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 dosing to reduce emissions and maintain SCR efficiency.
