FAQ

Q1: Are 059907807AA and SNS453 the same sensor?
A1: Yes. 059907807AA is the Volkswagen Group OE number, and SNS453 is the Continental/Vitesco sensor family reference used for the same NOx sensor module in VAG SCR systems.

Q2: What vehicles use this sensor?
A2: It is mainly used on VW Touareg, Audi Q7, and Porsche Cayenne diesel models equipped with 3.0 TDI 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 SNS453 family includes variants with different harness lengths for different 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.
