FAQ

Q1: Are 059907807AP, SNS0480B, and AAA9188880000 the same sensor?
A1: Yes. 059907807AP is the Volkswagen OE number, SNS0480B is the sensor family reference, and AAA9188880000 is the Continental/Vitesco manufacturing code for the same NOx sensor assembly used in VAG SCR systems.

Q2: What vehicles use this sensor?
A2: It is mainly used on VW 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 is used as a NOx sensor in SCR systems and may be installed in either inlet or outlet position depending on exhaust configuration. The same sensor family is used across multiple 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.
