How the Land Rover AdBlue system works
Covers: Discovery, Range Rover, Range Rover Sport, Defender and Evoque diesels.
Land Rover SCR systems use an AdBlue tank with pump and heater, managed by the engine ECU, with a countdown to a no-start condition. Many are used on estates, farms and off-road events.
Common Land Rover AdBlue faults we see first
- AdBlue pump and heater failures
- 'AdBlue: no start in X miles' warnings
- NOx sensor faults
- Quality sensor faults after contaminated fill
What we check before quoting
We read the engine ECU, check AdBlue quality and confirm how the vehicle is used before quoting.
Send us the registration and the exact dashboard message or fault code by WhatsApp. We confirm the ECU type and whether the job is suitable before arranging a visit.
Who this is for
Estate, farm and off-road event vehicles not used on public roads are the typical cases we are asked to look at.
Important — legal position
Disabling or removing a working emissions control system on a vehicle used on UK public roads is not lawful and will fail an MOT. This service is only for vehicles used off-road, in competition, on private land or exported. Road-registered vehicles in UK use get diagnosis and repair instead.
