FAQ

Q1: Are LR078809, 0281006779, and 0281006780 the same sensor?
A1: Yes. LR078809 is the Land Rover OE reference, while 0281006779 and 0281006780 are matching manufacturer reference numbers used for the same NOx sensor assembly in SCR systems.

Q2: What vehicles use this sensor?
A2: It is commonly used on Land Rover Discovery IV, Range Rover Sport (L320), Range Rover Velar, and Jaguar diesel models such as XF, XE, and F-Pace equipped with SCR (AdBlue) systems.

Q3: Is this inlet or outlet sensor?
A3: It can be used as inlet or outlet NOx sensor depending on exhaust configuration. Many Land Rover/Jaguar SCR systems use the same sensor type in different positions with different cable lengths.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) levels in exhaust gases and sends real-time data to the ECU to control AdBlue dosing, ensuring emissions compliance and SCR efficiency.
