Engine Overview
The Land Rover Discovery L462 is available with 10 engine variants — from 150 to 575 hp.
3.0-litre successor to the 276DT with the same structural crankshaft bearing weaknesses. Timing chains and injectors add further problem areas. Engine replacement costs of £5,000–£10,000 are a real possibility. Very short oil change intervals (max. 8,000 km) are mandatory. Only buy with complete documentation.
- !! Crankshaft bearing failure from design weakness from 180,000 km
The 306DT inherits the narrow crankshaft design of the 276DT. Bearing shells spin in operation and block oil galleries. Service bulletin SSM71816 covers 3.0L versions as well. Engine replacement costs £6,000–12,000.
Symptoms: Rhythmic knocking from the lower engine block (worse under load), oil pressure loss, metal particles in the oil filter - !! Timing chain and tensioner wear from 100,000 km
From around 80,000 km the 306DT chain tensioners and guides can wear. Rattling on cold start is the typical early warning. Left unattended, chain jump and engine damage follow.
Symptoms: Metallic rattling on cold start (disappears once warm), check engine light, P0008/P0016/P0017 - !! Injector over-fuelling with piston damage from 140,000 km
Certain 306DT injectors can over-fuel, causing extreme heat buildup in the cylinder and piston melting. Metal particles from the resulting damage destroy other engine components.
Symptoms: Individual cylinder power loss, rough engine noise, fault codes on individual injectors, metallic sounds
+ 2 more engine weaknesses + vehicle weaknesses
The 2.0L Ingenium four-cylinder diesel has been widely used since 2015 but suffers from structural weaknesses: timing chain (particularly vulnerable pre-2019), oil dilution from DPF regeneration on short trips, and turbocharger problems caused by poor oil quality. Oil changes every 10,000 km instead of the recommended 21,000 km are strongly advised.
- !! Timing chain stretches prematurely from 90,000 km
The 204DTD timing chain stretches prematurely due to worn plastic guides and degraded lubrication from oil dilution. Chains fitted before 2019 are particularly affected. Chain snap is possible.
Symptoms: Metallic rattling on cold start, engine warning light, power loss, fault codes P0016 or P0341 - !! Oil dilution from DPF regeneration from 30,000 km
Incomplete DPF regeneration cycles allow unburnt fuel to drip into the sump. Particularly critical on short trips with the transversely mounted engine — the distance between turbo and DPF is too great for passive regeneration.
Symptoms: Early service warning well before interval, oil level above max mark, fuel smell in oil, increased engine wear - !! Turbocharger failure due to oil starvation from 100,000 km
Turbochargers fail due to oil dilution-related lubrication degradation and plastic debris from timing chain guides. A second turbocharger can be destroyed by debris from the first.
Symptoms: Blue or black exhaust smoke, whistling or hissing noise, severe power loss, engine warning light

The 3.0L Ingenium straight-six diesel with 48V mild-hybrid is more refined than the 2.0L diesel. Main issues: oil filter housing recall N908 (fire risk, 2021–2025), EGR coking and DPF on short trips. The 48V DC-DC converter is the designed-in weak link of the MHEV system.
- !! Recall N908: oil filter housing can crack — fire risk
Incorrect plastic specification for the Ingenium I6 oil filter housing. The housing can crack and spray engine oil under pressure onto hot components such as the turbocharger. Fire risk. Recall N908.
Symptoms: Visible oil leak, oil puddles after parking, oil warning light, in severe cases smoke or fire - !! Turbocharger actuator failure from 80,000 km
The DT306 electronic turbocharger actuator develops faults from overheating and deposits. Repair is labour-intensive due to the engine layout.
Symptoms: Power loss, engine warning light, uneven acceleration, delayed turbo response - !! Injector failure from 150,000 km
The DT306 common rail injectors can fail from fuel contamination and internal wear. On the inline-six diesel all 6 injectors are affected.
Symptoms: Rough idle, diesel knock, black smoke, misfires, engine warning light

5.0-litre V8 Supercharged with excellent performance but well-known weaknesses. Timing chain set replacement is a matter of when, not if. Supercharger coupling and coolant pipes are further cost items. Running costs are substantial — only justifiable with a complete service history and low mileage.
- !! Timing chain guide plastic failure from 110,000 km
The most critical issue on the 508PS: plastic timing chain guides and hydraulic tensioners fail from around 100,000 km — faster on the supercharged engine due to higher load. Full repair costs €6,000–10,000.
Symptoms: Rattling on cold start (>5s), P0008/P0016/P0017, engine light, power loss - !! Plastic coolant pipe under supercharger bursts from 100,000 km
Several plastic coolant pipes (crossover pipes, thermostat housing) behind and under the supercharger become brittle from thermal cycling. Sudden failure often causes engine damage before the driver can react.
Symptoms: Sudden coolant loss, overheating warning, steam, limp mode - !! Supercharger torsional coupler wears out from 90,000 km
The Eaton supercharger torsional coupler — a plastic and metal spring assembly — breaks apart over time. Land Rover issued a TSB. The rattling sounds like gravel inside the supercharger and disappears under higher load.
Symptoms: Rattling from the supercharger at idle (sounds like stones in a blower), decreasing supercharger output
+ 2 more engine weaknesses + vehicle weaknesses
The 2.0L Ingenium turbocharged four-cylinder petrol shares the timing chain architecture with the diesel. Thermostat housing leaks are common and promote secondary damage to the piston cooling valve. No DPF oil dilution problem, but increased oil consumption at high mileages.
- !! Timing chain stretches prematurely from 90,000 km
The 204PT petrol shares its timing chain architecture with the diesel counterpart. Chains pre-2019 are particularly susceptible. Repair requires gearbox removal (20–30 hours labour).
Symptoms: Metallic rattling on cold start, engine warning light, rough idle, misfires - !! Thermostat housing leak and coolant loss from 70,000 km
The Ingenium petrol thermostat housing is known for coolant leaks. Escaping coolant can drip onto hot engine components and damage secondary parts.
Symptoms: Coolant loss without visible external leak, fluctuating engine temperature, steam from the engine bay, sweet smell - !! Turbocharger failure from 110,000 km
Turbocharger failure from oil starvation and bearing damage. On the 204PT the turbo oil supply is closely linked to the timing chain lubrication situation.
Symptoms: Whistling or howling noise, power loss under acceleration, oil warning light
+ 2 more engine weaknesses + vehicle weaknesses
The 3.0L Ingenium straight-six petrol with 48V MHEV is the most reliable modern JLR engine. Note oil filter housing recall N908. Turbocharger and cooling system benefit from regular oil changes and adequate cool-down time after spirited driving.
- !! Recall N908: oil filter housing can crack — fire risk
Incorrect plastic specification for the Ingenium I6 3.0L petrol oil filter housing. The housing can crack and spray engine oil onto hot components. Fire risk. Recall N908.
Symptoms: Visible oil leak, oil puddles, oil warning light, in severe cases smoke or fire - !! Timing chain — rattle and wear from 120,000 km
The PT306 inline-six shows timing chain wear with rattling on cold start. Although more robust than the 2.0L four-cylinder, wear and tensioner issues are documented at higher mileages.
Symptoms: Metallic rattling on cold start, rough idle, engine warning light with camshaft correlation errors - !! Turbocharger bearing and seal wear from 120,000 km
PT306 turbochargers develop bearing wear and oil blow-by particularly with insufficient oil change intervals. Allow cool-down time after spirited driving.
Symptoms: Whistling or howling noise, smoke from exhaust, power loss, elevated oil consumption

Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Air suspension — air springs leaking, compressor overloaded The Discovery 5 also suffers from the typical Land Rover air suspension weakness. Air springs become porous after 80,000–120,000 km. The compressor becomes overloaded and early system failures occur. Symptoms: Vehicle sags after parking, air suspension warning light, rough ride, compressor runs unusually long at start-up from 100,000 km | High |
