What is specific to the Discovery 2
The Discovery 2 was sold with both fuel types. Diesel derivatives (2.5 Td5 five-cylinder turbodiesel) use glow plugs, while petrol derivatives (V8 petrol) use spark plugs and ignition coils.
Electrical parts also changed across the 1999–2004 production span, so give the model year with the VIN.
Have this ready when you enquire
- The 17-character VIN from your licence document, which identifies your exact Series II (L318) (sold here 1999–2004) and its build.
- The engine code or number, because this model was sold with the 2.5 Td5 five-cylinder turbodiesel and V8 petrol.
- A photo of the old part or its part number, if you can get to it.

Discovery 2 electrical questions
Why does my Land Rover show so many warnings at once?
Modern Land Rovers are very sensitive to low voltage. A tired battery or poor earth connection can make several modules log faults at the same time. Test the battery and charging system, check the main earth points, then clear the codes and see which faults return.
What causes a Land Rover battery to go flat overnight?
A parasitic drain, where something stays on after the vehicle is locked, is the usual cause. Common culprits include a module that does not go to sleep, an aftermarket accessory, a faulty relay or an interior light switch. A workshop can measure the current drain and pull fuses one at a time to find it.
