How much does a Range Rover Evoque P300e engine replacement cost in the UK?

A reconditioned AJ20P3 petrol engine typically costs £3,000–£5,000 supply only, with fitting adding £1,200–£1,700. Use our calculator for a figure specific to your Evoque.

What are the common problems with the Evoque P300e engine?

Water pump and thermostat failure, timing chain tensioner wear, and hybrid system integration issues (often software‑related). The engine itself is robust with proper maintenance.

Is it worth replacing an Evoque P300e engine, or should I scrap the car?

Depends on vehicle value. An L551 Evoque P300e is a £20,000–£40,000 vehicle — a £4,000 recon is 10–20% of the car's value, making replacement a clear decision. This is well within our 60% Land Rover scrap threshold. Hybrid battery health may also affect value, but the engine replacement alone is viable.

How do I find my Evoque P300e engine code?

Listed on the VIN plate and vehicle documentation. The P300e engine code is AJ20P3 — a 1.5‑litre three‑cylinder Ingenium petrol. Tell us your registration date and we'll confirm it for free.

Can I prevent the timing chain issues on a P300e?

Yes — regular oil changes with the correct JLR‑spec oil and shortened intervals (5,000–7,500 miles) are the most effective prevention. At the first sign of cold‑start rattle, book an inspection immediately.

Common Problems

1. Cooling System Integrity (Water Pump & Thermostat)

Symptoms: Slow warm-up, temperature fluctuations, coolant loss, heater not working properly, engine warning light.

Typical mileage: 40,000–80,000 miles

Repair cost: £400–£900 (water pump and thermostat replacement) [PLACEHOLDER — confirm vs cost sheet]

Replacement cost: N/A — repair only

🟡 Monitor - book inspection soon

Our recommendation:

Like other Ingenium petrols, the AJ20P3's cooling system can suffer from water pump and thermostat failures. If you notice temperature fluctuations or coolant loss, have the system inspected. Replacing a failing water pump preventatively is far cheaper than the overheating damage it can cause. The hybrid system adds extra thermal load, so vigilance is key.

Replacement cost: N/A — repair only

🟡 Monitor - book inspection soon

Our recommendation:

2. Timing Chain Tensioner Wear

Symptoms: Rattling noise on cold start, metallic ticking from the front of the engine, engine warning light.

Typical mileage: 60,000–100,000 miles

Repair cost: £1,200–£2,500 (chain and tensioner replacement) [PLACEHOLDER — confirm vs cost sheet]

Replacement cost: N/A — repair only (if caught before catastrophic failure)

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

Our recommendation:

The 1.5 Ingenium shares the chain‑driven architecture of its larger siblings. Although less prone to chain issues than some earlier JLR units, tensioner wear can occur. Shorten oil change intervals to 5,000–7,500 miles and use the correct oil spec. At the first sign of cold‑start rattle, have the tensioners inspected — catching it early saves you a major repair bill.

3. Hybrid System Integration Issues (Not Engine‑Specific)

Symptoms: Reduced power, engine running constantly, warning lights, failure to switch to EV mode.

Typical mileage: Any — depends on usage

Repair cost: Varies — often covered under warranty; out‑of‑warranty can be £500–£2,000+

Replacement cost: N/A — repair only

🟠 Check - book inspection urgently if warning lights appear

Our recommendation:

While not a direct engine failure, the PHEV system's integration can cause drivability issues. If the engine is running more than expected or EV mode is unavailable, have the hybrid system diagnostics run. Many issues are software‑related and can be resolved with updates, but hardware faults (e.g., battery cooling) need attention.

Buying This Evoque P300e? Check These First

Buy If

Documented cooling system maintenance (water pump, thermostat replaced)
No cold‑start rattle — evidence of regular oil changes (5k–7.5k intervals)
Full JLR service history with correct oil spec
Hybrid system software up‑to‑date (dealer records)

Avoid If

Cold‑start rattle with no timing chain history — walk away
Temperature fluctuations with no cooling system history — potential overheating risk
Hybrid warning lights with no diagnosis — could indicate complex system faults
No service history — Ingenium engines are sensitive to neglect

Closing Verdict

The AJ20P3 is a modern, efficient three‑cylinder petrol engine that performs well in the Evoque PHEV. It's generally robust, but cooling system and timing chain tensioner wear are the main watchpoints. With the added complexity of the hybrid system, buy on full service history and pay attention to software updates. A well‑maintained P300e is a reliable, efficient flagship hybrid.

Coolant Level — Check for unexplained loss; water pump or thermostat may be failing

Service History — including engine era (AJ20P3) and confirmed oil‑change intervals (5k–7.5k)

EV Mode Operation — Test EV mode; if unavailable, hybrid system may have issues

Engine Running Behaviour — Does the engine run more than expected? Could indicate hybrid control issues

Oil Consumption — Does it use more than 1L per 1,000 miles?
