How much does a Land Rover Range Rover Td6 engine replacement cost in the UK?

A reconditioned Td6 3.0-litre BMW M57 engine typically costs £2,800–£4,500 supply only. Used engines are available from £1,500–£2,800. Fitting adds £1,200–£1,800 depending on your location and workshop. Main dealer new engines are no longer available — the M57 has been out of production for many years.

Is the Land Rover Range Rover Td6 engine reliable?

The BMW M57 straight-six diesel is widely regarded as one of the most durable diesel engines ever made — smooth, torquey, and capable of 200,000+ miles. However, it has known issues: timing chain stretch (if oil changes are neglected), injector wear, and DPF clogging (urban use). The engine itself is solid — the Td6's genuine weak point is the GM-sourced 5L40E automatic gearbox.

What are the common problems with the Land Rover Range Rover Td6?

The most frequently reported issues are timing chain stretch (particularly with neglected oil changes), injector wear, DPF clogging (short urban journeys), and the GM 5L40E gearbox — which suffers from premature valve body and torque converter wear. It's a matter of 'when, not if' for the gearbox.

Is it worth replacing a Range Rover Td6 engine, or should I scrap the car?

Depends on vehicle value. Against a well-kept £8,000 L322 Td6, a £3,500 recon is 44% of the car's value — approaching our 60% Land Rover threshold. Against a tired £4,000 example, the same recon exceeds the threshold — get a scrap valuation first. However, well-maintained Td6 L322s are becoming collectable — and the engine is often the least of your worries compared to the gearbox.

How do I find my Range Rover Td6 engine code?

Listed on the VIN plate and vehicle documentation. The Td6 carries the engine code M57D30 (also referred to as 306D1 in Land Rover parts documentation). It's a 2.9-litre straight-six turbo diesel used in the Range Rover L322 from 2002 to 2006.

Can I repair the timing chain, or does it need full engine replacement?

Yes — if caught early. A preventative timing chain and tensioner replacement costs £800–£1,800. The M57's timing chain is located at the front of the engine (unlike the problematic N47 rear-chain design), making it more accessible. If ignored and the chain snaps, the engine is an interference design — pistons and valves collide, resulting in catastrophic engine damage. At the first sign of cold-start rattle, book an inspection immediately. Regular oil changes using BMW LL-04 approved oil are the single most effective preventative measure.

Common Problems

1. Timing Chain Stretch

Symptoms: Metallic rattling noise on cold start, rough idling, engine misfires, engine warning light.

Typical mileage: 80,000–150,000 miles (worse with neglected oil changes)

Repair cost: £800–£1,800 (chain + tensioner replacement)【PLACEHOLDER — confirm vs cost sheet】

Replacement cost: £2,800–£5,500 (if chain snaps — engine is an interference design)

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

Our recommendation:

The M57's timing chain is located at the front of the engine (unlike the problematic N47 rear-chain design), making it more accessible — but it's still a labour-intensive job. BMW diesel timing chains are known to stretch over time, especially when regular oil changes using BMW LL-04 approved oil have been neglected. With proper maintenance, the chain generally does not require preventative replacement. At the first sign of cold-start rattle, get the chain and tensioners inspected immediately.

2. Injector Wear / Failure

Symptoms: Rough idle, poor acceleration, increased fuel consumption, diesel knock, black smoke.

Typical mileage: 80,000–150,000 miles

Repair cost: £400–£1,200 (injector replacement or refurbishment)

Replacement cost: N/A — repair only

🟡 Monitor - book inspection soon

Our recommendation:

The M57's injectors are sensitive to fuel quality. Clogged or failing injectors are a common pattern on higher-mileage examples. If your Td6 starts to exhibit rough running or poor fuel economy, have the injectors tested and cleaned or replaced as needed. Regular fuel filter changes are recommended.

Read the full injector failure guide

3. GM 5L40E Gearbox Failure

Symptoms: Harsh shifting, slipping between gears, delayed engagement, transmission warning light, complete loss of drive.

Typical mileage: 60,000–120,000 miles

Repair cost: £1,500–£3,000 (gearbox rebuild or replacement)

Replacement cost: N/A — transmission, not engine

🟠 Check - book inspection urgently if symptoms appear

Our recommendation:

This is the Td6's Achilles heel. The GM-sourced 5L40E automatic gearbox fitted to Td6 models suffers from premature wear of the valve body and torque converter due to poor-quality aluminium castings. It's a matter of "when, not if". If you're buying a Td6, budget for a gearbox rebuild — and avoid remapping the engine, as the gearbox can't handle the stock torque rating, let alone increased power. Look for evidence of transmission fluid changes (every 40,000–60,000 miles is recommended).

Buying This Td6? Check These First

Buy If

Documented timing chain inspection or replacement history
Evidence of regular transmission fluid changes (every 40,000–60,000 miles)
Full service history with BMW LL-04 approved oil changes at 10,000-mile (or less) intervals
No cold-start rattle — a quiet startup suggests healthy timing chain

Avoid If

Cold-start rattle with no timing chain history
No proof of gearbox fluid changes — the 5L40E is the Td6's weak link
Poor service history — the M57 is durable but unforgiving of neglect
Engine warning light with injector or timing-related codes and no diagnosis

Closing Verdict

The Td6 is the entry-level L322 Range Rover, powered by BMW's legendary M57 straight-six diesel. The engine itself is one of the most durable diesels ever made — smooth, torquey, and capable of 200,000+ miles. But the GM 5L40E gearbox is the Td6's genuine weak point — it fails, and it fails often. Buy on documented history, not on faith. A well-maintained Td6 is a £5,000–£10,000 classic; a neglected one with a failing gearbox is a £3,000 project.

Buying Checklist

Before you buy a used Land Rover Range Rover Td6 (or before you commit to an engine replacement), check these:

Service History — including the Td6 era (2002–2006) and confirmed oil-change intervals using BMW LL-04 spec oil

Gearbox Health — Any history of harsh shifting, slipping, or transmission fluid changes? (5L40E weak point)

Injector Performance — Any rough idle, poor acceleration, or increased fuel consumption?

DPF Check — Check for DPF warning light or evidence of regeneration issues (urban-driven vehicles are high risk)

Smoke Check — Black smoke can indicate injector or turbo issues

Engine Warning Light — Have codes been read? Any unresolved timing, injector, or DPF issues?

MOT History — Check for emissions-related failures (DPF, injector, or EGR-related)
