FAQ

Q1: Are 4G0907807J and 5WK97212 the same sensor?
A1: Yes. 4G0907807J is the Volkswagen Group OE number, and 5WK97212 is the Continental sensor reference used for the same NOx sensor module.

Q2: What vehicles use this sensor?
A2: It is mainly used on Audi A6 (C7) and Audi A7 3.0 TDI diesel models with SCR (AdBlue) emissions systems.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either inlet or outlet depending on the SCR system layout. The same sensor family 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, helping reduce emissions and protect the SCR catalyst system.
