What is specific to the Discovery Sport
The Discovery Sport was sold with both fuel types. Diesel derivatives (2.2 TD4 turbodiesel, 2.2 SD4 turbodiesel and D180 2.0 turbodiesel) use glow plugs, while petrol derivatives (2.0 Si4 turbo petrol and 2.0 turbo petrol, 183kW) use spark plugs and ignition coils.
Electrical parts also changed across the 2015–present production span, so give the model year with the VIN.

Discovery Sport 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.
