- Age-related
- What to inspect
- Cycle all cameras and screens
CoolingMedium
Coolant loss and thermostat housing leaks
- Typically appears
- 70,000+ miles
- What to inspect
- Check the coolant level and look for crusting
Engine and ExhaustHigh
Frequent DPF warnings and rising engine oil levels due to diesel fuel dilution during aborted regeneration cycles.
- Typically appears
- 30,000-50,000 miles
- What to inspect
- Pull the engine oil dipstick to check if the level is above the maximum mark and smell the oil for a distinct diesel odour.
Bodywork and InteriorMedium
Water ingress into the cabin causing damp carpets and potential Body Control Module (BCM) electrical faults.
- Typically appears
- 4-6 years
- What to inspect
- Press your hand firmly into the front footwell carpets, particularly on the passenger side, to feel for dampness and check for a musty cabin smell.
Body and TrimLow
Powered inner tailgate flap fails to deploy or retract, often accompanied by a grinding noise or warning beeps.
- Typically appears
- 40,000-70,000 miles
- What to inspect
- Open the main boot lid and press the button for the inner tailgate. Ensure it drops flat and raises completely without hesitation or grinding sounds.
Electrical and BodyMedium
Door latch actuators fail, causing one or more doors to remain unlocked when the vehicle is secured, or refusing to open.
- Typically appears
- 50,000-80,000 miles
- What to inspect
- Lock the vehicle with the key fob, put the fob out of proximity range, and physically pull all four exterior door handles to ensure they are locked.

Build my inspection planFrequently asked questions
Is an Ingenium diesel risky?
Early cars are. Look for chain work evidence or a later build.
Deal breaker?
A sagging corner combined with no service history.
Who buys these?
Towing families, so check the towbar and brakes.
Are the 2.0-litre four-cylinder engines underpowered for a car this size?
The 2.0-litre SD4 diesel produces 240bhp and adequate torque, making it perfectly capable for daily driving and motorway cruising. However, fully laden or when towing heavy loads, it lacks the effortless low-end grunt of the 3.0-litre V6 or straight-six options. Dealers should steer buyers intending to tow towards the larger capacity six-cylinder models.
What is the service interval, and should buyers stick to it?
Land Rover officially states 21,000 miles or 24 months for routine servicing on the L462. However, UK master technicians strongly advise halving this to 10,000 miles or 12 months. Extended intervals exacerbate oil dilution issues and accelerate timing chain wear. Always check the history for frequent, preventative oil changes rather than adherence to the maximum schedule.
How reliable is the rotary gear selector on earlier models?
The pop-up rotary gear selector used on pre-facelift models can occasionally stick in the lowered position, preventing the driver from selecting a gear. This is usually caused by a failing internal solenoid or a weak battery. If it hesitates to rise upon starting the engine, the entire selector module will likely require replacement.
