How much does a Range Rover Sport D250 engine replacement cost in the UK?

A reconditioned Range Rover Sport D250 (AJ20D6) engine typically costs £4,500–£6,500 supply only. Fitting adds £2,000–£3,000 depending on location and workshop rates. Used engines start from £2,800–£4,500 supply only. Main dealer new engines start from £10,000–£15,000+ supply only.

Is the Range Rover Sport D250 engine reliable?

The AJ20D6 is a 3.0-litre six-cylinder Ingenium diesel introduced in the Range Rover Sport from July 2020. It's generally considered more reliable than the 2.0-litre four-cylinder Ingenium diesel, with a good service life (250,000+ km). However, DPF clogging in urban use, timing chain tensioner wear, and EGR cooler issues are well-documented patterns across the Ingenium diesel family.

What are the common problems with the Range Rover Sport D250?

The main known issues are: (1) DPF clogging — particularly on vehicles used for short urban journeys, (2) Timing chain tensioner wear — a known pattern across Ingenium diesels, and (3) EGR cooler coolant leaks — a vulnerability across Land Rover's diesel engine range.

Is it worth replacing a Range Rover Sport D250 engine, or should I scrap the car?

Depends on vehicle value and condition. Against a well-kept £25,000–£45,000 Range Rover Sport D250, a £4,500–£6,500 recon is 10–25% of the car's value — worth it given Range Rover Sport values have remained relatively strong. However, for higher-mileage examples, evaluate the vehicle's overall condition before committing.

How do I find my Range Rover Sport D250 engine code?

The D250 uses the AJ20D6 (also known as DT306) — a 3.0-litre six-cylinder diesel producing 249 PS and 600 Nm of torque. The engine code is stamped on the cylinder block. Tell us your registration and we'll confirm it for free.

Can I prevent timing chain failure on the D250?

Prevention is not guaranteed, but you can significantly reduce the risk: (1) Change oil every 10,000–12,000 miles with the correct JLR-spec oil, (2) Avoid short urban journeys — regular motorway runs allow DPF regeneration to complete, and (3) Never ignore cold-start rattle — book an inspection immediately if you hear it. Even with perfect maintenance, timing chain tensioner wear remains a risk on higher-mileage examples.

Common Problems

1. Diesel Particulate Filter (DPF) Clogging

Symptoms: DPF warning light, reduced performance, increased fuel consumption, "Restricted Performance" message on instrument cluster, engine warning light

Typical mileage: Any mileage — short urban journeys accelerate the issue

Repair cost: £300–£800 (forced DPF regeneration) / £1,000–£2,500 (DPF replacement)

Replacement cost: N/A — repair only (does not progress to engine replacement if addressed)

🟠 Check - book inspection urgently if warning appears

Our recommendation:

Like all modern diesels, the D250's 3.0-litre Ingenium diesel is sensitive to DPF clogging if used predominantly for short urban trips. The vehicle's 48V mild-hybrid system helps, but it doesn't eliminate the need for regular motorway running to complete passive DPF regenerations. If you're buying a D250 primarily for city use, factor in occasional longer runs or consider the P400 petrol instead. If the DPF warning appears, book a forced regeneration immediately — ignoring it can lead to expensive DPF replacement.

🟠 Check - book inspection urgently if warning appears

Our recommendation:

2. Timing Chain Tensioner Wear

Symptoms: Cold-start rattling lasting 1–30 seconds, metallic ticking from engine, engine warning light, rough running

Typical mileage: 80,000–120,000 miles

Repair cost: £1,500–£3,000 (preventative chain, tensioners and guides)

Replacement cost: £6,500–£10,000 (if chain snaps — full engine replacement)

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

Our recommendation:

The AJ20D6 shares the Ingenium diesel family's timing chain design. While the six-cylinder unit is more robust than the 2.0-litre four-cylinder, timing chain tensioner wear remains a documented pattern across the Ingenium diesel range. At the first sign of cold-start rattle, get the chain inspected — a £1,500–£3,000 preventative repair is dramatically cheaper than the £6,500+ replacement that follows a snapped chain. The chain is rear-mounted on many Ingenium diesel engines, significantly increasing labour costs.

Read the full timing chain failure guide

3. EGR Cooler Coolant Leak

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

Typical mileage: Any mileage — a known vulnerability across Land Rover diesel engines

Repair cost: £750–£1,100 (EGR cooler replacement)

Replacement cost: N/A — repair only (does not typically progress to engine replacement if addressed)

🟠 Check - book inspection urgently if coolant level drops frequently

Our recommendation:

The EGR cooler is a known vulnerability across Land Rover's diesel engine range. Internal cooler leaks can cause coolant contamination and, in extreme cases, hydro-lock and catastrophic engine damage. If you're topping up coolant regularly without visible external leaks, book a pressure test immediately. A £750–£1,100 EGR cooler replacement is far cheaper than the engine damage that follows if ignored.

Buying This Range Rover Sport D250? Check These First

Buy If

Full service history with 10,000–12,000-mile oil change intervals — the Ingenium is unforgiving of neglect
Evidence of regular motorway use (DPF health)
No cold-start rattle — this is a critical warning sign
Remaining manufacturer warranty — these are complex vehicles

Avoid If

Any cold-start rattle — this is a warning sign of timing chain tensioner wear
DPF warning lights or "Restricted Performance" messages
Coolant loss with no documented fix — could indicate EGR cooler failure
No service history or extended oil change intervals — the Ingenium diesel family is unforgiving of neglect

Closing Verdict

The Range Rover Sport D250's AJ20D6 is a modern, sophisticated 3.0-litre six-cylinder diesel that represents a meaningful step up from the four-cylinder Ingenium units in terms of refinement and reliability. The engine has a good service life (250,000+ km), but DPF clogging in urban use, timing chain tensioner wear, and EGR cooler issues remain well-documented patterns across the Ingenium diesel family. Buy with full service history, evidence of regular motorway use, and budget for preventative maintenance. Without history? Approach with caution — the repair bills can be substantial.

Buying Checklist

Before you buy a used Land Rover Range Rover Sport D250 (or before you commit to an engine replacement), check these:

Cold Start — Listen for rattling or ticking from the engine (timing chain tensioner warning — this is critical)

DPF History — Ask about driving patterns; short urban journeys are a red flag

Service History — Including the AJ20D6 engine and confirmed 10,000–12,000-mile oil change intervals — non-negotiable

Coolant Level — Check for unexplained loss (EGR cooler leak)

Restricted Performance — Any warning messages? This often indicates DPF or turbo issues

Smoke Check — White smoke on startup (EGR cooler or injector issues)

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

Warranty Status — Manufacturer warranty is valuable on these complex vehicles
