We apply our repair‑to‑value threshold to every Land Rover and Range Rover model – using real 2025 UK enquiry data, quoted supply costs, and independent specialist labour rates. Here is the honest verdict for each engine, so you know when to repair and when to walk away.
The short answer: you should scrap a Land Rover when the repair or replacement cost exceeds 60% of the vehicle's current market value. That threshold is the single best predictor of whether owners regret repairing. Below it, most are glad they fixed it; above it, most wish they had walked away.
Next step: use the decision matrix and worked example below to run your own numbers, or try our Repair vs Replace Calculator for an instant verdict.
Cross‑reference your vehicle's approximate current trade value against the replacement quote you've been given. This is the same matrix we use across every model‑specific economics page on this site.
| Vehicle Value | Quote up to £3,000 | £3,000–£6,000 | £6,000–£9,000 | £9,000+ |
|---|---|---|---|---|
| £3,000–£5,000 | ⚠️ Watch | 🔴 Scrap | 🔴 Scrap | 🔴 Scrap |
| £5,000–£9,000 | ✅ Safe | ⚠️ Watch | 🔴 Scrap | 🔴 Scrap |
| £9,000–£14,000 | ✅ Safe | ✅ Safe | ⚠️ Watch | 🔴 Scrap |
| £14,000–£22,000 | ✅ Safe | ✅ Safe | ✅ Safe | ⚠️ Watch |

Value bands are indicative, built from typical UK trade valuations for the model years most commonly enquired about in our data [PLACEHOLDER — confirm vs cost sheet]. Always check your own vehicle's current trade and private valuation before applying this matrix. The matrix assumes a reconditioned engine with supply and fit – used engines are cheaper but carry higher risk.
This is the exact case we see most often: a Discovery 4 with the 306DT engine that has suffered catastrophic crankshaft bearing failure. Here is how we work out whether to repair, replace or scrap.
Every Land Rover and Range Rover model we see in our 2025 UK enquiry data, with typical replacement costs and a verdict based on a representative vehicle value. The verdicts are guidance, not a guarantee – always use your own car's value.
| Model | Typical Engine | Typical Recon S&F | Typical Vehicle Value | R‑to‑V Ratio | Verdict |
|---|---|---|---|---|---|
| Freelander 2 L359 | 224DT 2.2 Duratorq | £2,000–£3,500 [EM-QUOTE] | £2,500–£5,000 | 50–80% | Scrap on most examples |
| Discovery 4 L319 | 306DT 3.0 SDV6 | £6,500–£9,500 [EM-QUOTE] | £6,000–£14,000 | 50–95% | Scrap on sub‑£10k examples |
| Discovery Sport L550 (pre‑2019) | 204DTD Ingenium D | £3,500–£5,800 [EM-QUOTE] | £8,000–£16,000 | 30–55% | Watch on older examples |
| Discovery Sport L550 (post‑2019) | 204DTD (revised) | £3,500–£5,800 | £14,000–£35,000 | 15–30% | Safe |
| Evoque L538 (pre‑2019) | 204DTD / 224DT | £2,000–£5,800 | £5,000–£12,000 | 25–70% | Watch / Scrap on lower‑value examples |
| Evoque L551 (post‑2019) | 204DTD (revised) / 204PT | £3,000–£5,800 | £16,000–£38,000 | 10–30% | Safe |
| Range Rover L405 | 306DT / 508PS SDV8 | £6,500–£12,000 | £14,000–£55,000 | 15–55% | Safe across the range |
| Range Rover Sport L494 | 306DT / 508PS | £5,000–£12,000 | £12,000–£55,000 | 15–60% | Safe on most, watch on older examples |
| Range Rover Sport L320 | 276DT / 368DT | £5,000–£8,000 | £4,000–£12,000 | 40–80% | Watch / Scrap on sub‑£7k examples |
| Defender L663 | 204DTD / 306DT | £3,500–£9,500 | £35,000–£90,000 | 5–20% | Safe – strong residual values absorb cost |
| Velar L560 | 204DTD / 204PT | £3,000–£5,800 | £18,000–£50,000 | 10–30% | Safe |
These verdicts assume average condition and typical trade valuation. A well‑maintained, low‑mileage Discovery 4 with a documented history may justify spending above the threshold – our framework explains how to make that judgment. For a full list of known failure patterns, see the Failure Database.
Sometimes the best financial decision is to walk away. These are the Land Rover scenarios where our data suggests scrapping or parting out is the better choice.
Late in its value curve, a 224DT diesel replacement frequently exceeds 70% of trade value. With typical Freelander 2 values under £5,000, a recon at £2,000–£3,500 often pushes the ratio above 60%. Our full analysis is in Is It Worth Replacing a Freelander Engine?
The 306DT crankshaft failure is catastrophic and expensive. If your Discovery 4 is worth less than £10,000, a recon at £6,500–£9,500 will almost certainly exceed the 60% threshold. We cover this in detail in our Discovery SDV6 case study and our dedicated 306DT write‑off guide.
Pre‑2019 Ingenium diesel tensioner failures are common, and with early Discovery Sport values now sitting below £10,000 on many examples, a recon at £3,500–£5,800 can push the ratio to 60% or higher – especially if the vehicle also needs suspension or gearbox work. See Discovery Sport economics for the full picture.
Below this line, almost no engine fault clears the 60% threshold. Selling for parts or to a specialist breaker is usually the financially honest outcome – our scrap value guide explains how that figure is reached.
If your Land Rover also needs a gearbox, air suspension or a new infotainment system, the cumulative repair cost can push the total well beyond the value of the vehicle – even if the engine alone would have cleared the threshold. Use our Repair vs Replace Calculator to factor in all costs.
The 60% rule is our repair‑to‑value threshold: if a repair or replacement engine costs more than 60% of your Land Rover's current market value, the honest verdict is usually to scrap or sell for parts rather than repair. It is a starting guide, not an absolute cut‑off, and we always show the full working so you can judge your own case.
Use a combination of Auto Trader, Parkers, and your local trade guide – but the most accurate figure is what a dealer would offer you part‑ex, or what similar vehicles are actually selling for. Our Engine Value Checker can help you get a ballpark figure based on your model, year and mileage.
Yes – a used engine is usually cheaper (£1,500–£4,500) and can sometimes bring the repair‑to‑value ratio below 60% even on a lower‑value vehicle. However, a used engine carries no warranty and unknown history. A reconditioned engine costs more but includes a rebuild warranty. Our Reconditioned vs Used vs Rebuilt guide explains the trade‑offs.
It depends on the vehicle's value. If your Discovery 4 or Range Rover Sport is worth less than about £11,000–£16,000, a 306DT failure is almost always a write‑off. If it's worth more than that, repair may be viable. Our 306DT write‑off guide has a full breakdown by model.
The rule itself is constant, but the answer it produces varies enormously by model because vehicle values vary so much across the range. A Defender's strong residual values mean the same repair cost clears the threshold comfortably; a higher‑mileage Freelander 2 near the bottom of its value curve fails the same threshold at a far lower repair cost.
Contact a specialist breaker – many will collect the vehicle and offer a cash price based on the condition of the body, interior and remaining mechanical parts. We recommend getting at least three quotes before committing. Our scrap value guide explains how to get the best price.
