Land Rover Discovery 306DT/276DT/204DTD Engine SolutionsUK Specialists

A Land Rover Discovery engine replacement costs from £2,850 for a reconditioned unit to £9,100 for high-performance petrol variants, supply-only. Supply & fit packages typically add £1,200-£2,500 depending on workshop location. Prices vary by engine code, with 306DT diesel the most common and competitively priced option across Discovery 4 and 5 models.

• Rebuilt 2.7 TDV6 engines start around £3,200 supply-only UK-wide
• 3.0 SDV6 306DT replacements range £3,450-£5,600 depending on mileage
• Ingenium 2.0L AJ200D units cost £3,600-£5,100 due to timing chain complexity
• V8 petrol 508PN engines command £5,800-£7,900 for specialist rebuilds
• All quotes include 12-month unlimited mileage warranty as standard

Timing chain failure on the 2.0L Ingenium diesel (AJ200D) and oil pump casing failure on 2.7/3.0 TDV6 units (276DT/306DT) dominate Land Rover Discovery engine fault reports. Both issues cause catastrophic damage if warning signs like rattling or low oil pressure are ignored, making early diagnosis critical for cost-effective replacement decisions.

• AJ200D timing chains wear prematurely due to oil dilution from DPF regeneration cycles
• 276DT/306DT oil pumps suffer casing cracks leading to sudden oil pressure loss
• Turbocharger actuator faults (P00Q6 code) frequently affect twin-turbo 306DT engines
• EGR cooler leaks cause coolant loss and overheating on high-mileage TDV6 units
• Early symptom recognition can prevent total engine seizure and reduce replacement costs

Your Land Rover Discovery engine code appears on the V5C registration document under "engine number", on the engine bay identification plate, or by entering your reg on our free lookup tool. The most common codes are 276DT (2.7 TDV6), 306DT (3.0 SDV6), and AJ200D (2.0 Ingenium diesel).

• Check V5C section D.2 for the factory engine code reference
• Engine bay plaque near the firewall lists code and serial number
• Discovery 3 (2004-2009) typically uses 276DT 2.7L V6 diesel
• Discovery 4/5 (2010-present) predominantly feature 306DT 3.0L units
• AJ200D 2.0L Ingenium appears in late-model Discovery 5 and Sport

For Land Rover Discovery engines suffering catastrophic failure like seized crankshafts or snapped timing chains, a professionally rebuilt replacement engine offers superior value and warranty protection versus on-site rebuilds. Reconditioned units from our UK specialists include bench-testing, updated failure-prone components, and a 12-month unlimited mileage warranty as standard coverage.

• Rebuilt engines replace all wear items: bearings, seals, timing components, oil pump
• Supply-only prices start £2,850; supply & fit adds £1,200-£2,500 workshop labour
• Rebuilds on-vehicle risk missing hidden damage like crank scoring or head cracks
• Warranty coverage on replacement engines protects against premature repeat failure
• Core return policy refunds £300-£800 if original block is undamaged

Every Land Rover Discovery replacement engine supplied through EnginesMarket carries a minimum 12-month unlimited mileage warranty covering all major internal components. This includes crankshaft, pistons, cylinder heads, turbochargers, and high-pressure fuel systems. Warranty terms are transferable between owners and valid at any UK garage for peace of mind.

• 12-month unlimited mileage warranty standard on all rebuilt and reconditioned units
• Coverage includes crankshaft, pistons, cylinder heads, turbos, and fuel injection systems
• Warranty is transferable if you sell your Land Rover Discovery within the term
• Claims processed directly with the supplying specialist, no dealer involvement required
• Supply & fit packages include labour warranty for installation workmanship

Yes, our network of Land Rover Discovery engine specialists covers all UK mainland postcodes for supply and fit engine replacement. Once you compare quotes, your chosen workshop arranges collection or delivery of your vehicle, completes the engine swap in 2-3 days, and handles core return logistics for your old unit.

• Over 120 verified Land Rover specialist garages across England, Scotland, Wales
• Fixed-price fitting quotes include all labour, fluids, and diagnostic recalibration
• Most workshops offer courtesy cars or collection/delivery services for convenience
• Engine replacement typically completed in 2-3 working days from arrival
• All fitting centres follow JLR-spec torque settings and calibration procedures

If your Land Rover Discovery shows persistent knocking from the bottom end, zero oil pressure on the dash, or white smoke with coolant loss, these indicate catastrophic internal failure requiring engine replacement. Less severe issues like turbo faults or EGR problems may be repairable without full Land Rover Discovery engine replacement.

• Deep knocking or rattling from the crankshaft area signals bearing failure
• Zero oil pressure warning with no visible leaks suggests pump or pickup failure
• White exhaust smoke with sweet smell indicates coolant entering combustion chambers
• Seized engine that won't turn over confirms internal mechanical destruction
• Diagnostic codes P0016, P0087, or P00Q6 often precede major Land Rover Discovery engine failure

The cheapest Land Rover Discovery engine replacement option is a grade-A used engine from a verified breaker, starting around £2,350 supply-only. However, reconditioned units from £2,850 offer better long-term value with warranty protection, updated failure-prone components, and bench-testing that used engines cannot guarantee for peace of mind.

• Used engines from breakers start £2,350 but carry unknown mileage and history
• Reconditioned engines from £2,850 include new bearings, seals, and timing components
• Core return refunds of £300-£800 reduce net cost if original block is sound
• Supply-only option saves £1,200-£2,500 if you have a trusted local fitter
• Avoid non-UK suppliers; import duties and shipping often erase apparent savings

The 3.0L SDV6 (306DT) in Discovery 4 and early Discovery 5 models offers the best balance of reliability and performance when oil pump upgrades are fitted. Avoid the 2.0L Ingenium diesel (AJ200D) for high-mileage use due to timing chain vulnerability, and be cautious with pre-2015 306DT units lacking Gen2 oil pump revisions.

• 306DT Gen2 (2015+) features revised oil pump casing preventing catastrophic failure
• AJ200D Ingenium diesel requires strict oil changes every 10k miles to protect timing chain
• 276DT 2.7L TDV6 is robust but oil pump upgrades are essential preventative maintenance
• Petrol V8 units (508PN) are rare but mechanically simple with fewer failure points
• Regular servicing with JLR-spec oil is critical for all Land Rover Discovery engine longevity

With strict adherence to JLR service intervals and use of approved oils, Land Rover Discovery diesel engines (276DT, 306DT) commonly reach 150,000-200,000 miles before major overhaul. The 2.0L Ingenium AJ200D requires more vigilant maintenance; timing chain issues can emerge before 100,000 miles if oil changes are delayed or DPF regeneration cycles are excessive.

• 306DT engines with Gen2 oil pump revisions regularly exceed 180,000 miles trouble-free
• AJ200D Ingenium units need oil changes every 10k miles, not the official 18k
• Turbocharger lifespan averages 120,000 miles; premature failure often signals underlying issues
• Using non-spec oil accelerates timing chain wear on all Land Rover Discovery diesel engines
• Full service history significantly increases resale value and reduces replacement engine costs

Fitting a different engine code in your Land Rover Discovery is technically possible but risks MOT failure, insurance invalidation, and emissions non-compliance. Stick to the original factory engine code (276DT, 306DT, AJ200D, or 508PN) for your model year to ensure legal road use and retain warranty coverage on your Land Rover Discovery engine replacement.

• Engine swaps must match original emissions standard for MOT compliance
• ECU recalibration is required if changing between diesel and petrol variants
• Insurance providers may void coverage for unreported engine code modifications
• Specialist Land Rover garages can advise on compatible Land Rover Discovery engine codes
• Using the correct code preserves Terrain Response and air suspension functionality
