Why Choose Engine Finders for Your Range Rover L405 Engine?

Searching for a Range Rover L405 engine replacement or Range Rover L405 rebuild engine near you? The L405 (2012-2022) ran an unusually wide engine spread - from the long-serving 306DT V6 diesel through to late-production Ingenium units - so getting the right rebuild for your exact code matters more here than on most single-engine-family generations. We match every Range Rover L405 engine replacement to your confirmed engine code, with OEM-spec parts and a 12-month unlimited-mileage warranty, so your Range Rover L405 replacement engine is right the first time.

  • ✔ Widest Engine Coverage on the L405

    TDV6 through to late Ingenium - we source the exact engine code for your specific build year.

Range Rover L405 Engines for Sale | Engine Finders

The Range Rover L405 (2012-2022) replaced the L322 on a new aluminium-intensive platform, cutting weight significantly over its predecessor and marking a genuine step change in how the Range Rover was engineered. Production ran to 2021, with 2022 registrations covering outgoing market stock, so you may see L405s registered right up to that year even though manufacturing had effectively ended. For UK owners now searching for a Range Rover L405 engine replacement, it's worth knowing this generation covers more engine variety than almost any other Range Rover generation - from the original TDV6 diesel through to late-production Ingenium units. Engine Finders sources verified reconditioned and rebuilt units across the full L405 engine spread, matched to your exact confirmed engine code rather than a generic "Range Rover engine" assumption.

Range Rover L405 Replacement Engines

The L405 ran an unusually wide engine spread across its decade of production. Here's how the range breaks down:

  • TDV6 / SDV6 (2012-2022) - 3.0L V6 diesel, 306DT family. The most common engine across the range; SDV6 badges generally denote a later or higher state of tune than TDV6, not a different engine outright.
  • SDV6 Hybrid (2012-2022) - 3.0L V6 diesel-electric hybrid. Combines the 306DT diesel with a hybrid system; rebuild scope should always be confirmed at quote stage given the added hybrid hardware.
  • 4.4 SDV8 (2012-2022) - 4.4L V8 diesel, 448DT family. A lower-volume engine than the V6, with more limited parts availability to match.
  • 3.0 SCV6 (2012-2022) - 3.0L supercharged V6 petrol, 306PS/AJ126 family. Sits below the 5.0 V8 in the L405 petrol range.
  • 5.0 V8 / 5.0 Supercharged (2012-2022) - 5.0L V8 petrol, AJ133 family. Covers both naturally-aspirated and supercharged (508PS) variants - confirm which you have before ordering.
  • Late Ingenium (late-production) - P400e plug-in hybrid, P360/P400 mild-hybrid petrol, D250/D300/D350 mild-hybrid diesel, adopted ahead of the L460 changeover.

Because the L405 spans a full decade with genuinely different engine architecture across that span, two L405s built a few years apart can require completely different replacement engines - always confirm your exact code before ordering.

L405 Models & Engine Codes

Trim level and build year both influence which specific engine your Range Rover L405 carries:

  • Early production centred on TDV6 diesel and the 5.0 V8 petrol, the two mainstay engines through most of the L405's life.
  • SDV8 and the supercharged 508PS V8 served buyers prioritising towing capacity or outright performance respectively.
  • SDV6 Hybrid targeted efficiency-focused buyers wanting reduced running costs without stepping down to a four-cylinder unit.
  • Late in the model's life, P400e, P360/P400 and D250/D300/D350 Ingenium units arrived ahead of the L460 changeover, effectively previewing the next generation's architecture.

Given this spread, checking your exact engine code against your VIN is genuinely the only reliable way to confirm what your L405 needs - badge names alone don't tell the full story on a model with this much production-run variation.

Buy Used and Second-Hand Range Rover L405 Engines

We offer used, reconditioned, rebuilt and remanufactured Range Rover L405 units across the entire engine range - TDV6/SDV6, SDV8, SCV6, 5.0 V8 and late Ingenium alike:

  • Used - lowest cost, suited to buyers with verified low mileage and clear provenance. More uncertainty on lower-volume engines like the SDV8 given limited parts availability.
  • Reconditioned - inspected, with documented 306DT wear patterns addressed as standard on TDV6/SDV6 units.
  • Rebuilt - stripped and rebuilt to factory spec, suited to higher-mileage use.
  • Remanufactured - full OEM-standard rebuild, the closest option to factory-fresh condition.

Every option is bench-tested before dispatch and covered by our standard 12-month warranty, regardless of which L405 engine you need.

L405 Engines in Stock

Stock availability varies by engine - TDV6/SDV6 and the 5.0 V8 are the most commonly requested and tend to be quickest to source, while SDV8 and late-production Ingenium units may need a longer lead time. Every reconditioned L405 engine we supply includes:

  • 306DT diesel V6 units inspected per specialist-documented wear patterns
  • Timing chain tensioner checks on late-production Ingenium units
  • Hybrid-scope verification on SDV6 Hybrid and P400e builds
  • New gaskets, seals and oil pump on every single rebuild

Every unit is bench-tested before it leaves our network, confirming correct idle, oil pressure and torque delivery for your specific L405 engine.

Warranty for Replacement Range Rover L405 Engines

All reconditioned and rebuilt L405 engines come with the same standard of cover regardless of which of the six engine families your build requires:

  • 12-month, unlimited-mileage warranty
  • UK-wide supply and fit network
  • Bench-test verification before dispatch

Engine Finders is a price comparison marketplace - warranty terms are set by our vetted UK suppliers and confirmed at quote stage. We'd always recommend reading these in full before proceeding.

Frequently Asked Questions - Range Rover L405 Engines
Which Range Rover L405 engine is most reliable?

There's no single confirmed 'most reliable' engine across public sources for the Range Rover L405 - condition and service history matter more than which of the six engine families (TDV6, SDV6, SDV8, SCV6, 5.0 V8 or late Ingenium) your vehicle runs. The later Ingenium units are generally regarded as more consistent, though timing chain tensioner wear has been reported on these too, so no engine is entirely free of documented concerns. Always check service history regardless of engine, and factor a pre-purchase inspection into your budget alongside the price of the vehicle itself.

How much does a Range Rover L405 engine replacement cost?

Reconditioned TDV6/SDV6 units start from around £6,500, the 4.4 SDV8 from around £8,000 given its lower parts availability, the 5.0 supercharged V8 from around £5,500, and late-production P400e units from around £3,000 with hybrid scope confirmed at quote stage. All come supplied with a 12-month unlimited-mileage warranty. Get a specific quote matched to your confirmed engine code for the most accurate figure, since these six engine families vary considerably in both cost and parts availability.

What are common L405 TDV6 problems?

TDV6 and SDV6 units are part of the 306DT engine family, and known wear patterns are documented in specialist and owner sources covering this widely-used diesel V6. Because these engines have been in service for over a decade in many cases, higher-mileage examples benefit from careful pre-purchase inspection focused specifically on documented 306DT wear points rather than a general roadworthiness check alone. Our reconditioned TDV6/SDV6 units address these documented patterns as standard, backed by our 12-month warranty.

What are common L405 SDV8 problems?

The 4.4 SDV8 (448DT family) is a less common engine on the L405 than the TDV6/SDV6 diesel V6, meaning parts availability and specialist familiarity can be more limited. Specialist inspection is recommended given this lower volume, both when buying a used SDV8-equipped L405 and when sourcing a replacement engine, since fewer suppliers carry ready stock. This isn't a reflection of the SDV8 being inherently less capable - simply a smaller production run within the wider L405 range, priced from around £8,000 reconditioned to reflect that.

Is the L405 P400e reliable?

The P400e uses the Ingenium 2.0L PT204 petrol engine paired with a plug-in hybrid system, so overall reliability depends on more than the combustion engine alone. Battery condition and hybrid-system health matter just as much, and these components age differently to a conventional engine. Factor this into any reliability assessment on a late-production L405 P400e, and don't assume engine-only diagnostics tell you the full picture - a reconditioned P400e engine from us starts from around £3,000 with hybrid scope confirmed at quote stage.

What is the difference between TDV6 and SDV6?

Both are part of the same 306DT 3.0L diesel V6 family that powered the majority of Range Rover L405 builds - SDV6 badges generally denote a later or higher state of tune than TDV6, reflecting refinement across the L405's production run rather than a completely different unit. Because the badges look similar, confirm your exact engine code against your VIN rather than assuming from the trim name alone, particularly if you're sourcing a replacement engine where getting the precise code right matters for both fitment and warranty.

What L405 years should be avoided?

There's no single confirmed 'bad year' across public sources for the Range Rover L405, and we'd rather say that honestly than repeat an unverified claim. Condition and service history matter considerably more than model year alone for a vehicle this complex. Treat any specific year claim you encounter elsewhere with real caution until verified against your exact build and a proper inspection - this applies whether you're looking at an early TDV6 or a late-production Ingenium-equipped example.

How much is a reconditioned L405 engine?

Reconditioned Range Rover L405 engine cost ranges from around £5,500 for the 5.0 supercharged V8 up to £8,000+ for the 4.4 SDV8, with the common TDV6/SDV6 diesel typically around £6,500 and late-production P400e units from around £3,000 for the combustion engine element. Every option comes with a 12-month unlimited-mileage warranty as standard. Get a specific quote matched to your confirmed engine code for an accurate figure rather than relying on a general range.

Can an L405 engine be rebuilt?

Yes - reconditioned, rebuilt and remanufactured options are all available across the Range Rover L405's full engine range: TDV6/SDV6/SDV8 diesel, SCV6 and 5.0 V8 petrol, and the late-production P400e hybrid. Which option suits you depends on budget, how long you're keeping the vehicle, and typical annual mileage. Every rebuild comes with our standard 12-month warranty regardless of which of the six engine families your specific L405 requires.

What engine code is in my L405?

Your exact engine code is confirmed via your Vehicle Identification Number (VIN), which our team can help check against your registration details. This matters more on the L405 than on many models, given how significantly the engine range evolved across its decade-long production run - from the original TDV6 through to late-production Ingenium units. Engine-code formatting can vary between parts catalogues, so always cross-check against your own vehicle documentation before ordering.
