2.0L P400e Plug-in Hybrid
Hybrid
Test drive task: Perform a slow-speed crawl in EV mode. | Note: Listen closely for any drivetrain clunks or hesitation, as the complex integration between the electric motor and the 8-speed gearbox benefits from smooth software calibration.
Test drive task: Check the infotainment responsiveness. | Note: Navigate through several menus while driving; if the Pivi Pro system feels sluggish or exhibits flickering, it is worth asking the seller about software update history.
Test drive task: Inspect the air suspension behavior. | Note: Cycle through the different ride height settings while stationary to ensure the compressor engages quietly and the vehicle levels evenly without warning lights.
Test drive task: Verify the charging cable and port. | Note: Check that the charging port flap operates smoothly and that the provided charging cables are free of exterior damage or fraying.
Initial major health check recommended for battery cooling system efficiency.
Standard spark plug replacement and inspection of the high-voltage cable insulation.
Comprehensive service interval including major fluid flushes and suspension bush health assessment.
Always ensure your software is kept up to date through the SOTA (Software Over The Air) system.
Keep a consistent eye on the coolant levels for both the internal combustion engine and the hybrid battery cooling loops.
Regularly clean the charging port area to prevent debris from interfering with the seal.
Stick to the manufacturer-recommended service intervals, as the P400e engine is quite sophisticated.
Check tyre pressures frequently, as the added weight of the hybrid battery can influence wear patterns on the Defender's large footprint.
Estimated repair costs if issues arise
While very capable, these systems occasionally require attention as the vehicle ages. If the compressor slows down or you notice the vehicle sinking overnight, it is wise to plan for a potential pump or valve block service.
As part of your long-term ownership, you might eventually need to budget for a specialized diagnostic health check to monitor cell degradation, especially if you plan to keep the vehicle well past the warranty period.
Due to the clever regenerative braking on the P400e, friction brakes are used less often, which can lead to different wear patterns. If discs or pads require replacing, it is worth setting aside funds for high-quality components suited for the vehicle's weight.
