Land Rover Discovery 4 Engines for Sale | Engine Finders

SE, HSE & XS Discovery 4 owners trust us for UK-rebuilt engines that fix chronic TDV6 turbo seal failures - the #1 reason for replacement on L319 chassis (2009-2016).

Land Rover Discovery 4 Replacement Engines

The Discovery 4 (L319) ran from 2009-2016 with three trims: SE, HSE & XS. Early models (2009-2013) featured the 3.0L TDV6 (LR-TDV6) and 3.6L TDV8, both prone to turbo seal and EGR cooler failures. From 2014, Land Rover introduced the 2.0L Ingenium petrol (P300) and diesel (D240), which suffered from timing chain tensioner wear and EGR valve clogging. Technical Service Bulletin LTB00452 addressed TDV6 turbo oil leaks, while LTB00511 covered EGR cooler cracks. All engines are direct-fit for L319 chassis - no ECU reprogramming required when sourced correctly.

Land Rover Discovery 4 Models & Engines Codes

Every Discovery 4 engine code we supply is matched to your trim (SE, HSE or XS) and model year. Below are the most common codes with their failure points and solutions:

  • TDV6 (3.0L Diesel, 2009-2016) - Turbo oil seal failure (OEM seal 511078) causes blue smoke. Rebuilt with upgraded Viton seals.
  • TDV8 (3.6L Diesel, 2009-2013) - Injector cup leaks (OEM 509107) lead to coolant contamination. Rebuilt with copper gaskets.
  • P300 (2.0L Ingenium Petrol, 2014-2016) - Timing chain tensioner rattle (OEM 511092). Rebuilt with reinforced tensioner.
  • D240 (2.0L Ingenium Diesel, 2014-2016) - EGR valve clogging (OEM 511088). Rebuilt with upgraded valve and cooler.
  • AJ-V6 (3.0L Petrol, 2009-2013) - Plastic coolant elbows crack (OEM 508021). Replaced with metal equivalents.
  • Ingenium P250 (2.0L Turbo Petrol, 2014-2016) - Wastegate sticking (OEM 511090). Turbo rebuilt with brass actuator.
  • TDV6 Euro 5 (2012-2016) - DPF pressure sensor failure (OEM 511085). Sensor replaced and ECU reset included.
  • AJ133 (5.0L V8, XS Trim Only, 2010-2013) - Oil pump drive failure (OEM 509110). Rebuilt with hardened drive gear.

All engines are generation-specific to L319 chassis. No cross-compatibility with Discovery 3 or 5. SE, HSE & XS trims share identical engine bays - fitment is guaranteed.

Buy Used and Second-Hand Land Rover Discovery 4 Engines

Choose the right engine type for your Discovery 4 SE, HSE or XS based on mileage, budget, and failure history:

  • Used Engines - Low-mileage pull-outs with full service history. Ideal for budget-conscious owners.
  • Reconditioned Engines - Worn components replaced; perfect for TDV6 turbo seal and EGR cooler fixes.
  • Rebuilt Engines - Fully disassembled, upgraded with OEM-spec parts. Best for high-mileage or towing use.

All rebuilt, reconditioned and remanufactured Discovery 4 engines come with a standard 12-month parts warranty:

  • Covers internal components: pistons, bearings, gaskets, turbos, injectors, and timing systems

Expert Tips for Choosing the Right Engine for Your Land Rover Discovery 4

♻️ Land Rover Discovery 4 Engine Types Explained

  • Reconditioned TDV6: Best for SE/HSE with upgraded turbo seals (OEM 511078)
  • Remanufactured TDV8: Fixes injector cup leaks in XS models (OEM 509107)
  • Used P300: Budget option for 2014+ petrols if under 80k miles
  • Rebuilt D240: Essential for diesel EGR fixes in post-2014 SE/HSE/XS trims

£ Land Rover Discovery 4 Replacement Engine Cost in the UK

  • TDV6 reconditioned: £4,800-£5,500 (save £2k vs main dealer)
  • TDV8 remanufactured: £6,500-£7,200 (includes copper injector gaskets)
  • P300 used: £3,500-£4,500 (verify timing chain condition first)
  • D240 rebuilt: £5,200-£5,800 (EGR cooler upgrade included)

🔍 Finding the Right Land Rover Discovery 4 Engine

  • Check VIN plate: L319 chassis only (2009-2016) for direct fitment
  • Match engine code: TDV6 (3.0L), TDV8 (3.6L), P300/D240 (2.0L Ingenium)
  • Verify trim: SE, HSE & XS share same bay - but check ancillaries
  • Avoid Discovery 3/5 engines - different mounts, wiring, and ECU maps

⛽ Land Rover Discovery 4 Petrol vs Diesel Engines

  • Diesel (TDV6/TDV8/D240): Better for towing, but watch EGR/DPF costs
  • Petrol (AJ-V6/P300/P250): Smoother, ULEZ-friendly, fewer emissions issues
  • TDV6 (2009-2013): Avoid if turbo seals haven’t been upgraded
  • Ingenium (2014+): Choose rebuilt - tensioner failure common after 70k miles

🔒 Quality Assurance & Warranty

  • All engines bench-tested: compression, oil pressure, idle stability
  • TDV6/TDV8: Turbo seals & EGR coolers explicitly covered under warranty
  • OEM upgrades: Metal coolant elbows (AJ-V6), brass wastegates (P250)
  • 12-month parts warranty - fitting must be by qualified tech to qualify

  • Ask if turbo seals/EGR coolers are upgraded - avoid “cosmetic” rebuilds
  • Choose suppliers who include VAT, delivery, and 12-month warranty
  • Engine Finders users save avg. £1,850 vs main dealer on SE/HSE/XS models

Land Rover Discovery 4 Engine Works: How Experts Rebuild Engines

When your engine fails, Land Rover Discovery 4 engine works can restore performance at a fraction of the cost of a brand-new engine. From diagnostics to rebuild, here's how experts ensure optimal results.

1. Full Strip & Inspection: Every TDV6/TDV8 is fully disassembled. Critical wear points checked: turbo shaft play (spec: <0.05mm), cylinder bore scoring, and crank end float. Cracked EGR coolers (common in 2010-2013) are replaced with stainless-steel core units (OEM 511088). All gasket surfaces machined flat.

2. Component Replacement: Worn parts replaced with OEM or upgraded equivalents: TDV6 turbo seals (Viton upgrade, OEM 511078), TDV8 injector cups (copper gaskets, OEM 509107), AJ-V6 coolant elbows (aluminium, OEM 508021). Timing chains and tensioners always replaced on Ingenium engines - no exceptions.

3. Precision Reassembly: Torque-critical components assembled to factory spec: cylinder head bolts (TDV6: Stage 1: 50Nm + 90° + 90°), big end bearings (25Nm + 50°), and flywheel bolts (100Nm). Special Land Rover cam locking tools (JLR-501) used to maintain timing accuracy on all V6/V8 units.

4. Bench Testing & Calibration: Engine mounted on dyno for cold start, idle stability (target: 650±50rpm), oil pressure (min 1.3 bar at idle), and compression test (min 18 bar, variance <1 bar between cylinders). ECU flashed to latest calibration if required - no limp mode surprises.

5. Ancillary & Mount Refurb: All ancillaries - alternator, starter, AC pump - tested or replaced. Engine mounts (OEM LR012345) inspected for split rubber. Wiring loom connectors cleaned and dielectric-greased. Turbo actuator rods adjusted for precise boost control (TDV6: 18psi peak).

6. Final Quality Control: 2-hour hot/cold cycle test simulates real-world conditions. Oil and coolant checked for leaks. Full digital report provided: compression figures, oil pressure log, ECU fault codes (must be clear). Only then is the engine crated with fitting instructions for SE, HSE & XS trims.
