Discovery 3 TDV6
The Discovery 3 is closely associated with the 2.7-litre 276DT TDV6. On high-mileage vehicles, the decision may be between targeted repair, a documented rebuild and a correctly matched replacement engine.
TDV6 Engine Specialists
Land Rover TDV6 Engine Specialists in Ilford
The TDV6 badge covers some of the best-known diesel V6 engines fitted to Land Rover and Range Rover models, including the 2.7-litre 276DT and later 3.0-litre V6 diesel applications. When one of these engines develops a serious internal fault, the right solution depends on the exact engine code, vehicle, failure pattern and condition found during diagnosis.
Our JLR-focused workshop in Ilford works with TDV6 engine replacement, reconditioning, rebuild and fitting enquiries for Discovery and Range Rover vehicles. We start with the registration and engine code so the unit is matched to the actual vehicle rather than selected from engine size or badge alone.

TDV6 is a family name, not a complete compatibility check
A listing that says only “2.7 TDV6” or “3.0 TDV6” is not enough to order an engine safely. Send the registration, model year and any engine code or diagnostic report you already have before purchase or fitting.
Quick answer
What is a Land Rover TDV6 engine?
TDV6 is Land Rover terminology used for turbocharged diesel V6 powertrains across several model generations. The 2.7-litre 276DT is strongly associated with the Discovery 3 and first-generation Range Rover Sport, while 3.0-litre V6 diesel units appear in later Discovery and Range Rover applications. Exact outputs, turbo layouts and supporting systems vary by model year, so the vehicle registration and engine code should always be checked before quoting a replacement.
| TDV6 family | Engine code / example | Typical JLR applications | What to verify |
|---|---|---|---|
| 2.7-litre TDV6 | 276DT | Discovery 3; early Discovery 4; Range Rover Sport L320 | Registration, engine code, timing-belt history, ancillaries |
| 3.0-litre V6 diesel | 306DT / related variants | Discovery 4; later Discovery; Range Rover Sport / Range Rover applications | Exact code, output, turbo system, emissions equipment and model year |
Applications
Land Rover and Range Rover models that use TDV6 engines
TDV6 engines appear across several JLR platforms, but the same badge does not mean the same replacement unit will fit every vehicle. Chassis, electronics, turbo arrangement, emissions equipment and ancillary layout can differ even where displacement looks similar.
Discovery 4 TDV6
Discovery 4 vehicles can be encountered with 2.7- and 3.0-litre V6 diesel engines depending on model year and specification. Registration-based matching is essential before an engine is ordered.
Range Rover Sport TDV6
Early Range Rover Sport L320 vehicles commonly use the 2.7 TDV6, while later vehicles moved to 3.0-litre V6 diesel derivatives. Engine code and vehicle generation should be confirmed before quoting.
Range Rover / Vogue TDV6
Some Range Rover generations also use 3.0-litre V6 diesel powertrains. Because the installation and supporting systems differ from Discovery and Sport models, the exact vehicle must be checked rather than assuming interchangeability.
Engine identification
Why the TDV6 engine code matters
The engine code is one of the most useful identifiers when sourcing a TDV6 replacement. It helps separate different displacements and specifications that may otherwise be described simply as “Land Rover V6 diesel”. The registration provides the starting point, while the engine code and vehicle details help confirm compatibility.
| Check | Why it matters |
|---|---|
| Vehicle registration | Identifies model, model year and original specification. |
| Engine code | Separates 276DT, 306DT and related variants. |
| Chassis / model generation | Affects mounting, ancillaries, electronics and installation work. |
| Turbo and emissions equipment | EGR, DPF and turbo layout can vary by application. |
| Cause of original failure | Must be addressed before another engine is installed. |
Already know your engine code?
Send the code with the registration and fault details. If you do not know it, start with the registration and we can narrow down the correct TDV6 specification.
Common faults
TDV6 engine problems that need proper diagnosis
A TDV6 does not need replacement because one warning light appears. The symptoms below can be caused by more than one system, so diagnosis should come before a rebuild or replacement decision.
Bottom-end knock or bearing noise
A deep knock, metal contamination or a sudden loss of oil pressure can indicate serious internal damage. Continuing to run the engine may increase the extent of crankshaft and bearing damage.
Low oil pressure
Oil-pressure warnings should be treated seriously. The oil level, oil quality, pump, pickup, bearing clearances and any contamination need to be considered before the engine is condemned or another unit is fitted.
Timing-belt or fuel-pump-belt concerns
The 2.7 and 3.0 V6 diesel families use belt-driven timing systems, and workshop data for 306DT also identifies a separate injection-pump belt. Unknown service history is a reason to verify the complete timing-belt service rather than assuming it has been done.
Turbocharger and boost faults
Loss of power, smoke, underboost or oil in the intake can involve the turbocharger, boost control, hoses or oil supply. A turbo fault should be investigated before it damages a replacement engine.
EGR and DPF issues
EGR faults and diesel particulate filter problems can cause warning lights, restricted performance and poor running. They can coexist with an engine fault but do not automatically prove the engine itself needs replacing.
Overheating or coolant loss
Repeated overheating can affect head sealing, cylinder heads and internal clearances. Cooling-system faults should be corrected as part of the repair plan.
Poor compression, smoke or hard starting
Compression loss, injector issues, glow-plug faults, turbo problems and internal wear can produce overlapping symptoms. Testing is required before choosing repair, rebuild or replacement.
Repair options
Repair, rebuild or replace a TDV6 engine?
The best route depends on how far the damage has progressed. A single external fault may justify a targeted repair. A sound block with internal wear may be suitable for a rebuild. Severe crankshaft, block or widespread internal damage can make a reconditioned replacement engine the more practical option.
| Option | What it addresses | When it may suit |
|---|---|---|
| Targeted repair | A defined fault without widespread internal damage | EGR, cooling, turbo, fuel or timing-related work where the core engine remains serviceable |
| Engine rebuild | Original engine stripped, measured, machined where needed and rebuilt | Internal wear where the block and major components remain recoverable |
| Reconditioned replacement | A prepared replacement unit matched to the vehicle | Severe damage, seized engines or cases where rebuilding the original unit is not economical |
| Used engine | A second-hand unit supplied in used condition | Budget-led replacement where condition, compatibility and terms are acceptable |
Reconditioning
What should a TDV6 reconditioned engine process include?
Reconditioning should be a measured workshop process, not a cosmetic clean-up. The exact scope depends on the engine and damage found, but a proper job starts with strip-down and inspection before parts are ordered.
Diagnostic assessment
Fault codes, oil-pressure concerns, cooling history, smoke, noises and previous repair information are recorded before removal.
Strip-down and measurement
The engine is dismantled so crankshaft journals, bearings, bores, pistons, heads and sealing surfaces can be assessed.
Machining where required
Serviceable components are machined only where measurements show it is appropriate.
Replacement of worn components
Bearings, seals, gaskets, piston rings and timing-service parts are replaced according to the rebuild scope and engine condition.
Reassembly to specification
Clearances, fastener procedures and timing are checked during assembly.
Testing and installation checks
Oil pressure, cooling, leaks, fault codes and road behaviour are checked before handover where the engine is supplied and fitted.
Supply & fit
TDV6 engine supply and fitting in Ilford
Our workshop at 36-A Fowler Road, Ilford IG6 3UT provides a local base for TDV6 engine diagnosis, rebuild and replacement work. For customers who want one workshop to manage the job, we can discuss supply-and-fit rather than splitting engine sourcing and installation between different businesses.
Supply only
If your Land Rover or Range Rover is already with another garage, a correctly matched TDV6 engine can be discussed on a supply-only basis, subject to availability and specification.
Supply and fit
Where we handle the complete job, engine matching, removal, installation and post-fit checks can be planned together. The cause of the original failure should also be addressed before the replacement returns to service.
UK-wide support
We offer engine delivery and vehicle collection support across the UK. Send the registration and postcode so the available arrangement can be included with the quotation.
Cost & warranty
How much does a Land Rover TDV6 engine cost?
TDV6 engine cost varies because “TDV6” covers more than one engine and more than one vehicle. A 2.7 276DT replacement for a Discovery 3 is a different job from a 3.0 V6 diesel replacement in a later Discovery or Range Rover Sport.
- Engine code and displacement
- Vehicle and model generation
- Used, rebuilt or reconditioned replacement
- Condition of the original crankshaft, block and cylinder heads
- Turbocharger, EGR, DPF, fuel and cooling-system work required
- Supply only versus complete supply and fitting
Ask for the warranty terms in writing with the quote. Rebuilt and reconditioned engines come with a 6-month written warranty, with the exact conditions confirmed for the engine and service supplied.

Need a Land Rover TDV6 engine?
Send your registration and fault details. We will confirm the engine family, check the available route and provide a written quote before major work begins.
What does TDV6 mean on a Land Rover?
TDV6 is Land Rover terminology for turbocharged diesel V6 powertrains. It is not one single engine, so the displacement, engine code, model and year still need to be confirmed.
What is the 276DT engine?
276DT is the 2.7-litre V6 diesel engine code listed in our engine catalogue for Discovery 3 and Range Rover Sport applications. The catalogue lists 2720cc and 140 kW / 190 hp for this code.
What is the 306DT engine?
306DT is a 3.0-litre V6 diesel engine code used across later JLR applications. Exact output and installation vary by vehicle, so the code should be checked against the registration rather than treated as one universal specification.
Does a TDV6 use a timing belt or timing chain?
The main timing drive on the 2.7 and 3.0 JLR V6 diesel families is belt-driven. Workshop data also identifies a separate rear belt for the high-pressure fuel pump on these engines. Some internal camshaft components use chains, which is why complete engine identification matters when discussing a timing fault.
What are common TDV6 engine symptoms?
Heavy knocking, oil-pressure warnings, smoke, boost loss, overheating, coolant loss, hard starting and poor compression all justify diagnosis. EGR, DPF, fuel and turbo faults can produce similar symptoms and should not be confused with complete engine failure.
Can a TDV6 engine be rebuilt?
Often, yes, if the block and major components remain suitable. A strip-down and measurement process is needed before a rebuild can be recommended.
Do you supply reconditioned TDV6 engines?
Reconditioned-engine options can be discussed subject to the exact engine code and availability. Send the registration and fault details for matching.
Can you supply and fit a TDV6 engine in Ilford?
Yes. Supply-and-fit support is available through the Ilford workshop, with supply-only and wider UK logistics also available.
How much is a TDV6 replacement engine?
Cost depends on the engine code, vehicle, condition, replacement type and fitting scope. A registration-based written quotation is more useful than a generic engine price.
