3.0L SDV6 Diesel - AWD
Diesel
Test drive task: Perform a low-speed maneuver while turning the steering wheel lock-to-lock. | Detail: Keep an ear out for any groaning or knocking from the suspension, as the front lower control arm bushes on the L320 often wear out, leading to vague steering or vibrations at motorway speeds.
Check this by: Cycling through all height settings on the air suspension while parked on level ground. | Detail: Ensure the compressor is quiet and the vehicle lifts evenly. Uneven settling or a compressor that runs excessively might suggest a leak in the air bags or a tired compressor unit.
While driving: Monitor the dashboard for any flickering or sluggish gear changes. | Detail: The ZF 6-speed transmission is robust but benefits from clean fluid. Hesitation during downshifts or 'flaring' between gears could indicate that the valve body or torque converter may require attention.
Check this by: Inspecting the coolant reservoir and oil filler cap for milky residue. | Detail: It is worth checking for signs of cooling system integrity, as these engines can occasionally experience pressure build-up; keeping an eye on the coolant level regularly is a good habit for this specific model.
Consider a full transmission fluid and filter flush to keep those shifts silky smooth.
This is a great time to inspect the air suspension compressor and relay to ensure it remains reliable for longer trips.
The timing belt interval is crucial on the SDV6; if there is no documented record of this being done, it becomes a high priority for your peace of mind.
Stick to a strict 10,000km oil change interval using high-quality synthetic oil to protect the sophisticated engine components.
Regularly clear out the sunroof and door drains to prevent water ingress, which can play havoc with the sensitive electronics tucked under the carpets.
Keep a close eye on your tyre pressures, as these heavy vehicles wear rubber quickly if they are under-inflated.
Every six months, give the underside a quick check for any signs of surface corrosion or perished rubber seals.
Ensure your battery is always in tip-top shape, as low voltage often triggers 'ghost' electrical gremlins in the Range Rover's control modules.
Estimated repair costs if issues arise
Future Budget Planning: Should the compressor struggle to lift the vehicle, you might eventually need to budget for a replacement unit to maintain the ride quality and ground clearance.
Future Budget Planning: This is a significant piece of preventative maintenance on the SDV6. Depending on the car's history, it is wise to set aside funds for this job to ensure the engine remains protected.
Future Budget Planning: To keep the handling sharp and the ride compliant, you might eventually need to budget for replacing the front control arms and bushes as they naturally wear with age.
