FAQ

Q1: Are 04L907805CF and SNS0751C the same sensor?
A1: Yes. 04L907805CF is the Volkswagen OE number and SNS0751C / 5WK96737A are cross-references for the same NOx sensor module used in SCR diesel systems.

Q2: What vehicles use this sensor?
A2: It is widely used on Volkswagen Group 2.0 TDI vehicles including Golf, Passat, Tiguan, Audi A3/Q2, SEAT Leon, and Škoda Octavia 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 system configuration. Many VAG SCR systems use similar NOx sensors in multiple positions.

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 system efficiency.
