17 maintenance jobs for a Land Rover Defender L663 2.0 Ingenium diesel (D200 / D240), each with the parts, genuine part numbers, tools and steps.
Work safely: support the vehicle on axle stands, never a jack alone; let it cool first. Check figures against your workshop manual. You do this work at your own risk.
ENGINE · EVERY 21,000 MI / 2 YRS
Service: engine oil & filter
The core of every Land Rover service. Modern turbo engines and DPFs depend on the exact oil specification, not just the viscosity.
Many specialists halve this interval on high-mileage diesels, short-trip cars and anything that tows.
Parts
Engine oil (0W-20 or 0W-30 low-ash synthetic to the STJLR specification on the filler cap; ≈5.5 L)
Oil filter (to suit engine)LR073669
Sump plug washer (or sump plug and washer)LR073675
Tools
Drain tray
Socket set
Filter housing socket
Torque wrench
Diagnostic tool to reset the service indicator
Steps
Warm the engine, park level, and lift or raise the vehicle safely (on air suspension, select the jacking/workshop mode first so it does not move under you).
Remove the engine undertray. Drain the oil and renew the sump plug washer (some engines need a new plug).
Renew the filter: cartridge types unscrew the housing cap; fit the new O-rings supplied and tighten the cap to the torque on it.
Refill with 0W-20 or 0W-30 low-ash synthetic to the STJLR specification on the filler cap. Start, check for leaks, then check the level after a few minutes on the dipstick or in the instrument menu (≈5.5 L).
Reset the service indicator with the menu or a diagnostic tool, and log the service here.
BODY · EVERY 21,000 MI / 2 YRS
Pollen (cabin) filter
A blocked filter weakens the blower and mists the windows.
Parts
Pollen filter LR133345 / LR171252
Tools
Trim tools
Steps
Find the filter (behind the glovebox or under the scuttle panel, depending on model).
Note the airflow arrow, fit the new one the same way.
FUEL & AIR · EVERY 42,000 MI / 4 YRS
Air filter element
Turbo engines lose power and economy, and the airflow sensor gets dirty, when the filter blocks.
Bulkhead uses every second service; check your Maintenance Check Sheet for your exact vehicle.
Parts
Air filter LR129322
Tools
Screwdrivers / Torx
Steps
Release the airbox lid and lift out the element.
Wipe out the box, check the seal, fit the new element so it seats all round.
Check the intake ducts for splits. Inspect more often in dusty use.
FUEL & AIR · EVERY 42,000 MI / 4 YRS
Diesel fuel filter
Common-rail pumps and injectors are ruined by water and dirt.
Bulkhead uses every second service; some markets and engines need it more often.
Clean around the filter. Drain the water trap first if fitted.
Renew the element and seals.
Prime the system: on most of these engines, switch the ignition on and off several times (without starting) so the in-tank pump fills the filter. Some need a diagnostic tool routine.
Start and check for leaks; clear any fuel codes.
ENGINE · EVERY 21,000 MI / 2 YRS
Auxiliary belt & tensioner check
On many of these engines the auxiliary belt drives the water pump and alternator; a snapped belt can be pulled into the timing belt cover.
Parts
Auxiliary belt (if cracked)
Tools
Torch
Steps
Check the belt for cracks, missing ribs and glazing.
Check the tensioner holds steady with the engine running and the pulleys run quietly.
ENGINE · EVERY 21,000 MI / 2 YRS
DPF & EGR health check
Short trips stop the particulate filter regenerating. A blocked DPF puts the engine into limp mode and can dilute the oil with diesel.
Parts
None
Tools
Diagnostic tool with live data
Steps
Check for any DPF or engine warnings.
Read the soot loading and regeneration history with a diagnostic tool.
If you mostly do short trips, drive at a steady speed on a main road for 20–30 minutes every week or two.
Check the oil level is not rising (a sign of fuel dilution from failed regenerations).
ENGINE · EVERY 3 MONTHS
AdBlue level check
If the AdBlue tank runs dry the engine won't restart.
Parts
AdBlue (ISO 22241)
Tools
Funnel
Steps
Check the range in the instrument menu.
Top up through the blue filler with ISO 22241 AdBlue only.
COOLING · EVERY 10 YRS
Coolant change (10-year)
Land Rover renews the coolant every 10 years regardless of mileage. Check the level and strength every service.
Parts
Antifreeze concentrate (OAT antifreeze to Land Rover spec)
Hoses & clips (if needed) (replace any soft, swollen or cracked hoses)
Tools
Drain tray
Garden hose
Screwdrivers
Hydrometer or refractometer
Steps
Work on a cold engine only. Remove the expansion tank or radiator cap slowly.
Open the radiator drain (or remove the bottom hose) and the cylinder block drain tap or plug. Set the heater to hot.
Flush with clean water until it runs clear. Squeeze every hose: replace any that feel soft, crunchy or swollen.
Check the radiator fins, fan blades and (where fitted) the viscous coupling. A viscous fan should turn with some resistance when the engine is warm.
Refill with a 50% antifreeze mix (OAT antifreeze to Land Rover spec). Fill slowly to avoid air locks; on coil-sprung models use the bleed screw on the thermostat housing or radiator top where fitted.
Run the engine to working temperature with the cap off (or loose), top up as the level drops, refit the cap and check again when cold.
BRAKES · EVERY 21,000 MI / 2 YRS
Brakes, tyres & suspension inspection
Heavy vehicles with big wheels wear pads, discs and tyres quickly.
Parts
Brake pads (if under 3 mm)
Brake discs (if under minimum)
Tools
Jack and stands (or a lift)
Vernier
Torch
Steps
Check pad thickness and disc condition on every wheel (many models also have pad wear sensors).
Check tyres for wear, damage and age; check the spare.
Look for leaks at the dampers, and check ball joints and bushes for play.
Check brake pipes and hoses for corrosion and chafing.
BRAKES · EVERY 3 YRS
Brake fluid change
Land Rover renews brake fluid every 3 years regardless of mileage.
Parts
Brake fluid (DOT4 low-viscosity brake fluid to Land Rover spec (ESP/ABS systems))
Tools
Pressure bleeder
Diagnostic tool (ABS bleed routine on some models)
Steps
Bleed each wheel in the order in your workshop manual.
Some models need an ABS bleed routine run with a diagnostic tool.
Check the pedal is firm before driving.
TRANSMISSION · EVERY 60,000 MI / 5 YRS
Transfer box & locking-diff oil
Land Rover changes the transfer box and rear locking diff oil every 5 years on vehicles that have them.
Check your vehicle has a two-speed transfer box (a low-range button) and an electronic locking rear diff.
Drain and refill each to its level plug with the specified fluid.
TRANSMISSION · EVERY 60,000 MI / 6 YRS
Automatic gearbox fluid & differentials
Land Rover lists these fluids as long-life (changed at 10 years on many models). Specialists change the automatic gearbox fluid and filter, and the diff oils, sooner on a vehicle that tows or is kept beyond its warranty.
Bulkhead's advisory interval. The official Land Rover interval is longer; check your Maintenance Check Sheet.
Parts
ATF (ZF Lifeguard fluid for ZF gearboxes)
Gearbox sump pan / filter (to suit gearbox; the sump pan includes the filter on the 8-speed)
Differential oil (Land Rover-specified fluid)
Tools
Socket set
Fluid pump
Diagnostic tool (to read fluid temperature)
Steps
The ZF automatics are filled at a set fluid temperature (about 35–45 °C) with the engine running: you need a diagnostic tool to read it.
Renew the sump pan or filter and refill to the level plug as the workshop manual describes.
Drain and refill the front and rear differentials (and the transfer unit/PTU on transverse-engined models).
SUSPENSION · EVERY 21,000 MI / 2 YRS
Air suspension check
If your vehicle has air suspension, leaks and a tired compressor are the usual faults.
Parts
Air spring (if leaking)
Tools
Soapy water spray
Diagnostic tool
Steps
Park overnight on level ground; note any corner that has dropped.
Spray the air springs (folds at the bottom) and pipe joints with soapy water to find leaks.
Read the suspension codes; listen for the compressor running for long periods.
BRAKES · EVERY 21,000 MI / 2 YRS
Electric parking brake check
The electric park brake must hold on a slope; some models use small drum shoes inside the rear discs that need adjusting.
Parts
None
Tools
Diagnostic tool
Steps
Check it holds the vehicle on a steep slope.
Models with drum-in-disc shoes: check and adjust them as your manual describes (a diagnostic tool may be needed to set service mode).
Never work on the rear brakes without putting the EPB into service mode first.
BODY & CHASSIS · EVERY 1 YR
Underbody & corrosion check
Subframes, brake pipes and (on the Discovery 3/4 and Sport L320) the steel frame corrode in salty winters.
Parts
Cavity wax / underbody protection
Tools
Torch
Pressure washer
Steps
Wash the underside, then check the subframes, frame rails, brake and fuel pipes, and the rear arches.
Treat any bare metal and re-wax cavities.
SAFETY · EVERY 1 YR
Annual safety inspection
Do this before the MOT and you will rarely fail.
Parts
Bulbs & fuses (spares, if needed)
2 × Wiper blades (if worn)
Tools
Helper
Tyre gauge
Steps
Lights: every light works, including brake lights, indicators, reverse light and number plate light.
Wipers and washers clear the screen. Horn works.
Seat belts latch, retract and are not frayed. Seat mounts are secure.
Exhaust: no blows and the mountings are secure.
Tyres: tread depth, cuts, bulges and age. Check the spare too.
Brakes pull up straight and the handbrake holds on a hill.
SAFETY · EVERY MONTHLY
Monthly walk-round checks
Five minutes a month catches leaks and low levels before they become repairs.
Tyre pressures (including the spare) and look for cuts.
Look under the vehicle where it has been parked. Note the colour of any drips: brown/black = oil, green/blue/orange = coolant, red = ATF or PAS, clear and slippery = brake fluid.
All lights work.
