A failed engine is one of the most expensive problems a Discovery 5 owner can face. Prices vary widely depending on which engine your car has and what the quote actually includes.
Independent specialists currently advertise rebuilt Discovery 5 engines at roughly £5,500–£6,800 including VAT, with labour indicated. Supply-only used or reconditioned units are advertised from around £2,350, before fitting and possibly before VAT.
Owners have reported far higher bills, of £11,500–£17,500, for out-of-warranty replacements on the 2.0 Sd4.
Before you accept any figure, check three things: confirm the diagnosis, check your warranty status, and make sure the quote covers the same work as the others you are comparing.
Which Discovery 5 Engine Are You Replacing?
The Discovery 5 (L462) has used several different engine families since 2017. The engine fitted to your car affects both how easy a replacement is to find and how much it costs.
Engine Types and How They Affect Price
Engine | Years (approx.) | Type | Price pressure |
| 2.0 Td4 / Sd4 | 2017–2020 | Four-cylinder Ingenium diesel | Moderate; widely available, but quality varies |
| 3.0 Td6 / SDV6 | 2017–2020 | V6 diesel | Moderate to high |
| 2.0 Si4 / P300 | Various | Four-cylinder turbo petrol | Rare in the UK; fewer units on the market |
| 3.0 Si6 | 2017–2020 | Supercharged V6 petrol | Higher; rare in the UK |
| D250 / D300 | 2021 onwards | 3.0 six-cylinder mild-hybrid diesel | Higher; newer engine, fewer used units |
| P360 | 2021 onwards | 3.0 six-cylinder mild-hybrid petrol | Higher |
Autocar confirms that the facelifted D250 and D300 are 3.0-litre straight-six engines (Autocar). Some supplier pages list the D250 as a 2.0, which is wrong. If a quote names the wrong engine, ask the supplier to confirm the engine code before you pay a deposit.
RR Engine Works' Discovery 5 engine page covers rebuild and supply-and-fit options for this model.
How Much Does a Discovery 5 Engine Replacement Cost?
The figures below are advertised by third-party suppliers. They are not RR Engine Works prices, and they do not all include the same work.
Advertised UK Prices Compared
Source | Option | Scope | Price | VAT |
| LR Engine | Used engine | "From"; fitting not stated | £2,350 | Not stated |
| LR Engine | Reconditioned 2.0 / 3.0 | "From"; fitting not stated | £2,550 / £3,343.75 | Not stated |
| 1stChoice (breaker quotes) | Used 2.0 Sd4 / 3.0 Si6 | Supply only; ancillaries vary | £4,249 / £5,684 | Not stated |
| JLR Engines | Rebuilt D200 to P360 | Quotes stated to include labour | £5,500–£6,800 (est.) | Included |
| Owner reports (PistonHeads) | Replacement 2.0 Sd4 | Out of warranty; scope unclear | £11,500–£17,500 | Unclear |
Sources: LR Engine; 1stChoice; JLR Engines; PistonHeads.
These figures do not combine into a single range, because they measure different things. A low "from" price for a bare engine can end up close to a fitted rebuild price once labour, ancillaries and VAT are added.
Extras That Change the Final Bill
A complete quote should state each of the following:
- Labour. Removing and refitting the engine, including moving ancillaries across from the old engine.
- Ancillaries. Whether the turbo, injectors, sensors and wiring come with the new engine or are reused from yours.
- Consumables. Oil, filters, coolant, gaskets and mounts.
- ECU coding. Matching the engine management to your vehicle.
- Root-cause repairs. For example, DPF work on a diesel that failed through oil dilution, or an oil cooler and system flush after bearing failure.
- Exchange or core charge. Applied if your old engine cannot be returned for rebuilding.
- Recovery or collection. Needed if the car cannot be driven.
- VAT. Some advertised prices are "plus VAT".
RR Engine Works' supply and fit page says bare-engine prices are quoted plus VAT. Fitting is quoted in writing before work begins, and the fitting service covers moving ancillaries across, consumables, ECU coding and a logged road test. Ask for each item to be listed separately so you can compare quotes like-for-like.
Replace, Rebuild or Repair?
The cheapest engine is not always the cheapest outcome. The right choice depends on the type of damage and the car's value.
Making the Right Call for Your Discovery 5
Situation | Likely route |
| Car still under manufacturer warranty or an approved extended warranty | Claim first. Ask about goodwill if it has only recently expired |
| Timing chain wear caught early (2.0 diesel) | Repair, although engine removal may still be required |
| Crankshaft or bearing failure, block intact | A rebuild may be viable |
| Cracked block, seized engine, or debris throughout the oil system | Engine replacement |
| Warning lights only, no confirmed internal damage | Diagnose before agreeing to any engine work |
Stop driving and arrange recovery if the oil pressure warning shows, or if you hear knocking, notice a sudden loss of power with mechanical noise, or see smoke. Driving further can turn a rebuild into a replacement.
Before paying for any engine, ask the garage these questions:
- What caused the failure, and will that cause be fixed?
- Is the replacement used, reconditioned or rebuilt, and how was it tested?
- What does the warranty cover (unit, labour, or both), and what are the mileage limits?
- Does the quote include VAT, coding and ancillaries?
Frequently Asked Questions
Discovery 5 Engine Replacement Cost FAQs
How much does a Discovery 5 engine replacement cost?
Advertised rebuilt engines with labour start at around £5,500–£6,800 including VAT. Supply-only used units are advertised from about £2,350. Owners have reported bills of £11,500 or more for out-of-warranty replacements. The final cost depends on the engine type, the condition of the unit and what work is included.
Is a 2.0 Sd4 engine cheaper to replace than the 3.0?
The engine itself is often cheaper and easier to source. However, labour and root-cause repairs, such as dealing with oil dilution, can narrow the gap. Always compare quotes on the same scope of work.
Is it worth replacing the engine in a Discovery 5?
It often is, because the car usually holds more value than the cost of a replacement engine. Compare the full quote against the car's market value and check for other faults, such as the gearbox, before committing.
Will Land Rover replace the engine under warranty?
If the car is within its warranty and the failure is covered, yes. Keep your service records, because they support any claim and any request for goodwill.
What is the difference between reconditioned and rebuilt?
Suppliers use these terms inconsistently. Ask what was actually renewed: bearings, piston rings, the timing chain, seals and the oil pump. Also ask how the engine was tested.
How long does a Discovery 5 engine replacement take?
It depends on whether a suitable unit is available and how much extra work is needed. Ask for a realistic timeframe on your written quote.
