How much does a Land Rover Defender D240 engine replacement cost in the UK?

A reconditioned Defender D240 (204DTD) engine typically costs £3,500–£5,800 supply only. Fitting adds £650–£1,300 at independent specialist rates. Use our calculator for a figure specific to your vehicle.

Is the Land Rover Defender D240 engine reliable?

The 204DTD in the D240 is the single-turbo Ingenium diesel, a 2020–2021 short-run engine. It shares the pre-2019 timing chain tensioner risk profile that has defined the Ingenium D's reputation. Post-2019 revisions reduced failure rates but did not eliminate the risk entirely — buy on chain history.

What are the common problems with the Defender D240?

Timing chain tensioner wear (the defining failure mode), oil dilution from DPF regeneration (urban-use risk), and EGR cooler failure (coolant leaks into the exhaust system). All three are well-documented across the 204DTD family.

Is it worth replacing a Defender D240 engine, or should I scrap the car?

Against a well-kept £25,000 Defender D240, a £4,500 recon is 18% of the car's value — worth it. Against a higher-mileage example, the Land Rover scrap threshold of 60% means replacement remains viable across most D240 values, given the L663's strong residual values.

How do I find my Defender D240 engine code?

The engine code 204DTD is listed on the VIN plate and vehicle documentation. The D240 badge was only available 2020–2021 in the L663 Defender, so if your vehicle is a 2020 or early 2021 L663 diesel, it's almost certainly a 204DTD. Tell us your registration and we'll confirm for free.

Can I repair the 204DTD timing chain, or does it need replacement?

Yes — if caught early. A preventative chain replacement (£1,200–£2,500) is far cheaper than a catastrophic chain snap (£3,500–£5,800 engine replacement). At the first sign of cold-start rattle, book an inspection immediately.

Common Problems

1. Timing Chain Tensioner Failure (Pre-2019 Ingenium D)

Symptoms: Cold-start rattle, engine warning light, loss of power, metallic noises from the front of the engine.

Typical mileage: 60,000–120,000 miles

Repair cost: £1,200–£2,500 [EM-QUOTE]

Replacement cost: £3,500–£5,800 (catastrophic failure) [EM-QUOTE]

🔴 Immediate - if you hear rattle, book an inspection today

Our recommendation:

The Ingenium D timing chain tensioner is the single biggest reliability concern on the 204DTD. While the L663 Defender's 2020–2021 production run benefited from post-2019 revisions, this risk is not eliminated — it is merely reduced. Any cold-start rattle from a D240 must be investigated immediately. A £1,200–£2,500 preventative chain replacement is dramatically cheaper than a £3,500+ engine replacement.

Our recommendation:

2. Oil Dilution From DPF Regeneration

Symptoms: Rising oil level on dipstick, diesel smell in oil, DPF warning light, reduced fuel economy.

Typical mileage: Any mileage — urban-use pattern dependent

Repair cost: £150–£350 (oil change + forced regeneration) [EM-QUOTE]

Replacement cost: N/A — repair only

🟠 Check - book inspection urgently if oil level is rising

Our recommendation:

The 204DTD's DPF regeneration cycle can push unburnt fuel past the piston rings into the sump, diluting the engine oil and reducing its lubricating properties. This is a particular risk on vehicles used primarily for short urban journeys. Regular oil changes (6,000-mile intervals rather than JLR's extended schedule) and occasional motorway runs are the most effective prevention. If the oil level is rising on the dipstick, book an oil change and DPF inspection immediately.

3. EGR Cooler Failure

Symptoms: Coolant loss with no visible external leak, white exhaust smoke, occasional burning smell, engine warning light.

Typical mileage: Any mileage

Repair cost: £500–£1,200 [EM-QUOTE]

Replacement cost: N/A — repair only

🟠 Check - book inspection urgently if coolant is disappearing

Our recommendation:

EGR cooler failure is a known issue across the Ingenium diesel family, including the 204DTD in the L663 Defender. Coolant leaks into the exhaust system can lead to overheating and, if ignored, cylinder head damage. The EGR cooler itself is a replaceable component (£500–£1,200), and there have been JLR service actions covering certain VIN ranges. Check your vehicle's service history for any recall or goodwill work.

Buying This Defender D240? Check These First

Buy If

Documented timing chain history (proof of tensioner inspection or replacement)
Confirmed oil change intervals at 6,000 miles or less (not JLR's extended schedule)
Full service history with specialist attention, not just main dealer stamps
Urban-use history with regular motorway runs to clear the DPF

Avoid If

Cold-start rattle with no chain history — this is the defining failure mode
No proof of regular oil changes (oil dilution risk)
Service history gaps or long intervals (12,000+ miles between oil changes)
Engine warning light with no diagnosis — the 204DTD can hide expensive faults

Closing Verdict

The Defender D240's 204DTD is a capable, torquey engine that suits the L663 platform well — but it belongs to the pre-2019 Ingenium family that earned a reputation for timing chain tensioner failures. Post-2019 revisions reduced but did not eliminate the risk. This badge's 2020–2021 production window means every D240 is affected by the same design era; buy on chain history, not on low mileage alone.

Buying Checklist

Before you buy a used Land Rover Defender D240 (or before you commit to an engine replacement), check these:

Cold Start — Listen for rattle lasting 1–30 seconds (timing chain warning, 204DTD)

Service History — Including oil change intervals (6,000 miles recommended, not 12,000+)

Smoke Check — White smoke on startup can indicate EGR coolant leak

Turbo/Boost Check — Test acceleration; any lag, hesitation, or whistling?

DPF Regeneration — Check history; short journeys accelerate wear on all diesel Ingenium units

Oil Consumption — Does it use more than 1L per 1,000 miles? Rising oil level is equally concerning

Engine Warning Light — Have codes been read? Any unresolved issues?

MOT History — Check for emissions-related failures (DPF, EGR, NOx sensors)
