FAQ

Q1: Are A0091530728 and 5WK96657B the same sensor?
A1: Yes. A0091530728 is the Mercedes-Benz OE number, and 5WK96657B 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 Sprinter (W906) and E-Class E250 BlueTEC diesel models equipped with SCR (AdBlue) emissions systems.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either inlet or outlet depending on SCR configuration. The same sensor family is used with different harness lengths and mounting positions.

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