4.4L V8 Diesel - SDV8
Diesel
Gently accelerate and decelerate between 40-80km/h; listen for any hesitation or surging, as this could indicate issues with the turbo actuators on the SDV8 engine.
Cycle through the air suspension height settings while parked; ensure the compressor isn't overly noisy and the vehicle levels itself promptly without dash warnings.
Engage 'Dynamic' mode or corner briskly; check for any knocking or clunking sounds from the front lower control arm bushes, which can wear out due to the vehicle's significant weight.
Operate the infotainment screen and all electrical seats; confirm there is no flickering or lag, as these units can occasionally suffer from electrical gremlins in older L405 models.
Usually time to inspect the cooling system hoses and coolant reservoir for signs of plastic degradation.
Consider having the ZF 8-speed automatic transmission serviced; even if 'sealed for life', a fluid and pan filter change is wise for longevity.
Check the condition of the air suspension compressor and the ride height sensors for environmental wear.
Prioritise a full service history check to ensure engine oil changes have been carried out strictly every 12 months or 15,000km.
Check for any signs of oil seepage around the engine valley or cylinder heads as part of a pre-purchase inspection.
Verify the DPF (Diesel Particulate Filter) is healthy; regular highway driving is the best way to keep these clear in the NZ context.
Inspect the condition of the brake rotors and pads, as the SDV8 is heavy and consumes these parts faster than smaller SUVs.
Ensure the electronic parking brake engages and disengages silently and smoothly during your inspection.
Estimated repair costs if issues arise
Future Budget Planning: Should the compressor struggle to lift the vehicle, it's worth noting that these wear out over time. Depending on the car's history, you might eventually need to budget for a replacement pump or dryer unit to keep the ride smooth.
Future Budget Planning: Given the weight of the L405, the front suspension bushes are under constant pressure. In cars of this age, it is common to consider replacing the lower control arms to maintain that signature Range Rover steering precision.
Future Budget Planning: The SDV8 features complex twin-turbo setups. If this component needs attention in the future, the estimated cost in NZ reflects the specialized labor required to access and recalibrate the actuators.
