FAQ

Q1: Are 059907807C, 5WK96637B, and SNS458 the same sensor?
A1: Yes. 059907807C is the Volkswagen OE number, 5WK96637B is the Continental reference, and SNS458 is the sensor family code used for the same NOx sensor module in VAG SCR systems.

Q2: What vehicles use this sensor?
A2: It is commonly used on Volkswagen Touareg 3.0 TDI, Audi Q7 diesel, and Porsche Cayenne diesel models equipped with SCR (AdBlue) emissions systems.

Q3: Is this inlet or outlet sensor?
A3: It can be used as inlet or outlet NOx sensor depending on exhaust layout. The same sensor design is used in multiple positions with different harness lengths.

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