FAQ

Q1: Are A0091530128 and 5WK96659A the same sensor?
A1: Yes. A0091530128 is the Mercedes-Benz OE number, and 5WK96659A is the Continental/Vitesco 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 heavy-duty trucks such as Actros, Antos, and Arocs 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 depending on SCR system configuration. The same sensor family is shared across multiple positions with different cable lengths.

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