FAQ

Q1: What is LR104388 used for?
A1: LR104388 is a NOx sensor used in Land Rover diesel SCR (AdBlue) systems to measure nitrogen oxide levels in the exhaust and control emissions performance.

Q2: Which vehicles use this sensor?
A2: It is commonly used on Land Rover Discovery 5, Range Rover Sport, and Range Rover models equipped with 3.0 V6 diesel engines meeting Euro 6 / EU6 d-Temp standards.

Q3: Is this inlet or outlet sensor?
A3: Depending on the SCR system layout, LR104388 can be used as either upstream (pre-SCR) or downstream (post-SCR) NOx sensor in the exhaust system.

Q4: What does this sensor do?
A4: It monitors NOx (nitrogen oxide) levels in exhaust gases and sends real-time data to the ECU, allowing precise AdBlue dosing to reduce emissions and maintain SCR efficiency.
