FAQ

Q1: Are A0009057100 and 5WK96683A the same sensor?
A1: Yes. A0009057100 is the Mercedes-Benz OE number, and 5WK96683A 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 vehicles such as C-Class (W205), E-Class (W212/W213), GLC, GLE, ML, and S-Class equipped with Euro 6 SCR (AdBlue) emissions systems.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either inlet or outlet NOx sensor depending on exhaust layout. Many Mercedes SCR systems use identical sensor units in different positions.

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