FAQ

Q1: Are 059907807D and 5WK96623B the same sensor?
A1: Yes. 059907807D is the VW/Audi OE number, and 5WK96623B is the Continental NOx sensor reference used in SCR diesel systems.

Q2: What vehicles use this sensor?
A2: It is commonly used on Audi Q7, Q5, A6, A8 and VW Touareg 3.0 TDI diesel vehicles with Euro 5 SCR systems.

Q3: Is this inlet or outlet sensor?
A3: It is typically used as a downstream (post-catalyst / SCR outlet) NOx sensor depending on exhaust configuration.

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 injection, helping reduce emissions and maintain SCR efficiency.
