Land Rover Range Rover L322
Weaknesses, engine ratings and buying advice
The Range Rover L322 (2002–2012) is the classic full-size Range Rover of the 2000s and a chapter unto itself: it launched with BMW technology and, after the Ford takeover, gradually switched to Jaguar/Ford components. This mixed heritage makes it technically layered — and complex and expensive to run as it ages. As a full-size luxury off-roader it is cheap to buy today, but the low price is a trap: an L322 in poor condition can become a bottomless pit.
With the engines you have to look closely. The 3.6-litre V8 diesel (368DT) is torquey and effortless, but comes with delicate Siemens piezo injectors, of which four of the eight not uncommonly fail together — an expensive affair. The later 4.4-litre V8 diesel (448DT) has a known cast crankshaft weakness, where the forged crankshaft is the recommended upgrade. On the petrol side the naturally aspirated 4.4-litre AJ41 is the most sensible choice: developed in-house, more robust and longer-lived than some predecessors, as long as the plastic timing chain guide is kept an eye on. The supercharged V8 (AJ33S) and the big 5.0-litre naturally aspirated (508PN) sound magnificent, but share the typical eight-cylinder ailment: breaking timing chain guides and — on the supercharged unit — the dreaded plastic coolant pipe beneath the charger, which can burst suddenly and kill the engine. Preventive replacement with a metal pipe is essential here.
Regardless of engine, the classics are the chronically failing air suspension compressor, rust on the rear wheel arches and sills, a sticking electric parking brake, water-damaged control units beneath the seats, corroding parking sensors and shift shock in the ZF automatic gearbox. The air conditioning readily loses refrigerant.
Anyone buying an L322 should check the air suspension after it has stood for a while, inspect the area under the seats and the control units there for signs of water, scour the underbody for rust, and on the supercharged petrol establish whether the coolant pipe has already been replaced. A thick folder of documented, well-executed repairs is worth more than low mileage. Verdict: an imposing, cult luxury SUV with real presence — but only a sensible buy with deep pockets, a good workshop and plenty of patience. As a cheap daily driver, the L322 is the fastest route to financial frustration.

Engine Overview
The Land Rover Range Rover L322 is available with 6 engine variants — from 271 to 396 hp.
4.4-litre V8 diesel with a known cast crankshaft weakness — forged crankshaft upgrade recommended. Plastic timing chain tensioners and coolant pipes are critical weak points. Repairs can cost £4,000–£20,000. Only acceptable with a very well-maintained service history and oil changes at max. 8,000 km.
- !! Crankshaft fracture from casting weakness from 180,000 km
The production cast-iron crankshaft of the 448DT is known for premature cracking. Tuners and specialists recommend upgrading to a forged crankshaft. Repair costs are extreme.
Symptoms: Dull knocking from the engine block, oil pressure warning light, metallic noises, sudden engine seizure - !! Plastic timing chain tensioner failure from 120,000 km
The plastic timing chain tensioner of the 448DT is the single most critical weak point. Metallic rattling on cold start lasting more than 5 seconds warns of impending engine destruction. Typically affected from 100,000–160,000 km.
Symptoms: Loud metallic rattling on cold start (>5 seconds), check engine light P0008/P0016/P0017, power loss - !! Plastic coolant pipe under intake manifold from 100,000 km
The plastic coolant crossover pipe running under the intake manifold cracks from embrittlement. Sudden coolant loss threatens — the engine can be overheated before the temperature warning appears. Pre-emptive replacement with aluminium pipes is recommended.
Symptoms: Sudden coolant loss, overheating warning, steam, in worst case hydrolock
+ 2 more engine weaknesses + vehicle weaknesses
This 3.6-litre V8 diesel is a torque-rich, effortless powerplant that unfortunately carries sensitive Siemens piezo injectors — it is not unusual for four of the eight units to fail together. The water-cooled EGR cooler can slowly bleed coolant into the intercooler over years until the engine fails abruptly, so checking coolant level and the charge-air path is mandatory before buying. High-pressure pump failure with loss of rail pressure, carbon build-up on the variable-geometry turbo, and brittle plastic coolant lines complete the risk profile. Only genuinely durable with high-quality, gap-free maintenance.
- !! Piezo injector failure (often 4 of 8) from 130,000 km
The Siemens piezo injectors of the 368DT are very sensitive and expensive. Inspections frequently reveal multiple failed injectors (documented: 4 out of 8). New injectors cost approximately €500 each.
Symptoms: Rough running, individual cylinder fault codes, power loss, increased fuel consumption, limp mode - !! High-pressure pump failure with system pressure loss from 120,000 km
The 368DT high-pressure pump is prone to failure. Vehicles enter limp-home mode after 12–15 km of driving. Fault codes for low fuel rail pressure are typical.
Symptoms: Limp mode after a few kilometres, hard start, fault codes for low fuel rail pressure - !! EGR cooler leak: coolant into intercooler from 100,000 km
The water-cooled EGR cooler can pass coolant into the intercooler. Over roughly three years the coolant slowly fills the intercooler until it reaches the turbo and enters the engine, causing severe engine damage.
Symptoms: Sporadic power loss, white smoke, after years: sudden catastrophic engine failure
+ 2 more engine weaknesses + vehicle weaknesses
This 4.4-litre naturally aspirated V8 is an in-house design rather than a bought-in unit, and it is considered tougher and longer-lived than some predecessors, running reliably to high mileage when properly maintained. The timing chain uses plastic guides that grow brittle over time and can break; a metallic rattle is the warning sign. The VANOS seals wear and announce themselves through ticking and lost power, while the high-opening-temperature thermostat and the cooling system are known weak points. The PCV system should be checked regularly, as wear there drives up oil consumption. Overall a good-natured eight-cylinder as long as servicing is kept up.
- !! Plastic timing chain guide breaks from 120,000 km
The BMW M62 uses a very long single-row timing chain with plastic guides. The guides can break and shed fragments into the sump. Sunken fragments can block the oil pump pickup — engine damage possible.
Symptoms: Cold start rattling (chain tensioner), plastic particles in engine oil, check engine light, misfires - !! VANOS seals worn: clatter and power loss from 100,000 km
The VANOS units (BMW variable camshaft timing) deteriorate over time. Seals become porous, the cam phasers clatter and tick. The engine loses power and responsiveness at low RPM.
Symptoms: Tactile diesel-like clatter from the cylinder head at low RPM, power loss in the lower rev range, P0011/P0021 - !! Thermostat (105°C) and cooling system failures from 100,000 km
All M62-equipped L322s were delivered with a 105°C thermostat. The thermostat and coolant hoses are prone to premature wear. Heater hose connectors frequently break.
Symptoms: Coolant loss, overheating, broken heater connections, coolant warning light
+ 1 more engine weaknesses + vehicle weaknesses
Solid 5.0-litre V8 (naturally aspirated, no supercharger). Timing chain and guides are the known weak point from around 130,000 km. Short oil change intervals (max. 8,000 km) significantly reduce the risk. Replace plastic coolant pipes preventively with aluminium items. Character: refined V8 with decent power delivery.
- !! Timing chain guides and tensioners fail from 130,000 km
The AJ133 5.0L V8 (naturally aspirated) is known for premature wear of the plastic timing chain guides and hydraulic tensioners. The fault typically appears from 120,000–150,000 km. Extended oil change intervals are a frequent contributing factor.
Symptoms: Rattling/knocking on cold start, P0008/P0016/P0017, engine light, power loss - !! Plastic coolant pipes become brittle from 110,000 km
Like the supercharged V8, the naturally aspirated V8 has numerous plastic coolant pipes and fittings that become brittle and crack. Pre-emptive replacement with metal pipes (Euro AMP kit) is strongly recommended.
Symptoms: Sudden coolant loss, overheating warning, steam from the engine bay - !! Ignition coil failure and spark plug wear from 100,000 km
Ignition coils on the 5.0 V8 tend to fail, often in combination with oil-fouled spark plugs (caused by valve stem seals). Rough running and misfire codes on multiple cylinders simultaneously are typical.
Symptoms: Rough running, P030X misfire codes, engine light, oil-fouled spark plugs
+ 1 more engine weaknesses + vehicle weaknesses
4.2-litre V8 supercharged with performance but several critical weaknesses. The coolant pipe under the supercharger can rupture suddenly and cause engine damage — preventive replacement with aluminium pipes is strongly recommended. Supercharger torsion coupling wears from around 90,000 km. Budget for high running costs.
- !! Plastic coolant pipe under supercharger bursts from 100,000 km
The plastic coolant pipe running behind and under the supercharger cracks from thermal cycling-induced embrittlement. Coolant loss is sudden — by the time the overheating warning appears it is usually too late.
Symptoms: Sudden coolant loss, overheating warning, steam, engine damage if reaction is delayed - !! Supercharger snout: bearings and coupler wear out from 90,000 km
The Eaton supercharger coupler element — plastic and metal — wears out and gives way. Grinding noises from the supercharger or at idle point to bearing failure. Land Rover has issued a TSB on this subject.
Symptoms: Grinding or rattling noises from the supercharger, hesitation under acceleration, power loss - !! Timing chain and guides wear from 130,000 km
Like the naturally aspirated V8, the 4.2 SC also has timing chains with plastic guides that can wear. Cold start rattling is the typical warning sign. A missed inspection risks a jumped chain.
Symptoms: Metallic rattling on cold start, check engine light P0008/P0016, power loss
