FAQ

Q1: Are 4M0907807AF and SNS711A the same sensor?
A1: Yes. 4M0907807AF is the Volkswagen/Audi OE number, and SNS711A is the corresponding NOx sensor reference used in VAG SCR diesel systems.

Q2: What vehicles use this sensor?
A2: It is commonly used on Audi Q7, Q8, Volkswagen Touareg, and Porsche Cayenne diesel models equipped with Euro 6 SCR (AdBlue) systems.

Q3: Is this inlet or outlet sensor?
A3: Depending on exhaust layout, it can be used as SCR inlet or outlet NOx sensor. Many VAG systems use paired sensors with similar designs.

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