FAQ

Q1: Are A0009056900 and 5WK96681A the same sensor?
A1: Yes. A0009056900 is the Mercedes-Benz OEM part number, and 5WK96681A is the Continental/VDO NOx sensor reference used in SCR diesel systems.

Q2: What vehicles use this sensor?
A2: It is widely used on Mercedes-Benz diesel models such as C-Class W204, E-Class W212, CLS C218, Sprinter, Vito, and R-Class equipped with Euro 5 / Euro 6 SCR AdBlue systems.

Q3: What does this sensor do?
A3: It measures nitrogen oxide (NOx) levels in exhaust gases and sends real-time data to the ECU to control AdBlue dosing and reduce emissions in SCR systems.

Q4: Is it inlet or outlet sensor?
A4: It can be used as either upstream or downstream NOx sensor depending on the vehicle’s exhaust layout and SCR configuration.
