Is the Land Rover Range Rover Sport P510e engine reliable?

The AJ20P6 combustion engine itself is a robust Ingenium six-cylinder unit. However, the PHEV system introduces additional complexity. Known issues include AdBlue dosing valve faults causing MOT failures, coolant leaks, and battery concerns. A recall (R/2026/078) has been issued for certain 2023 model year vehicles relating to hybrid battery capacity.

What are the common problems with the Land Rover Range Rover Sport P510e?

AdBlue/emissions system faults (leading cause of MOT failures), coolant leaks (reported on vehicles as new as 3 months old), hybrid exhaust temperature sensor miscalibration, and potential battery issues. The complex dual emissions control system is prone to diagnostic false positives.

Is it worth replacing a Range Rover Sport P510e engine, or should I scrap the car?

Apply the 60% Land Rover scrap threshold: if your Range Rover Sport is worth £70,000 and a recon engine is £10,000 (14%), it's absolutely worth it. Even with a £15,000 battery replacement, total cost (£25,000) is 36% of the vehicle's value — within the threshold. These are high-value vehicles that justify significant repair spend.

How do I find my Land Rover Range Rover Sport P510e engine code?

The engine code is listed on the VIN plate and vehicle documentation. The P510e uses the AJ20P6 (also known as PT306) — a 3.0-litre twin-turbocharged straight-six petrol engine with a 105kW electric motor. Tell us your registration date and we'll confirm it for free.

Can I delete the AdBlue system to avoid MOT failures?

No — this is illegal under Section 42 of the Road Traffic Act 1988. The DVSA actively uses roadside scanners to detect emissions defeat devices, and penalties include fines up to £1,000 and MOT bans. Instead, use JLR-approved diagnostics and repairs.

Figures above reflect the only engine generation this badge ever used — the AJ20P6 PHEV. See the Era Map above for era-specific pricing. Note that battery replacement costs are separate — typically £8,000–£15,000 once the warranty expires.

Labour estimate: Fitting a Range Rover Sport P510e engine typically takes 15–25 hours at £65–£95/hr (independent). The complex PHEV system and high-voltage battery add significant labour time compared to non-hybrid engines.

Common Problems

1. AdBlue System & Emissions System Malfunctions

Symptoms: "Emissions System Malfunction" warning, AdBlue warning, MOT failure (active DTCs like P204F or P20EE), reduced power.

Typical mileage: Any mileage — can affect low-mileage examples.

Repair cost: £500–£2,000 (AdBlue dosing valve replacement, injector cleaning, SCR system repair).

Replacement cost: N/A — repair only; ignoring emissions warnings will result in MOT failure.

🟠 Check - book inspection urgently if warnings appear.

Our recommendation:

The P510e's dual emissions control system (AdBlue/SCR for the petrol engine plus hybrid-specific monitoring) is complex. Faulty AdBlue dosing valves or clogged injector nozzles are a leading cause of MOT failure. In mild-hybrid mode, reduced exhaust flow can cause abnormally low temperature readings, tricking the ECU. Never delete or bypass the AdBlue system — this is illegal under the Road Traffic Act 1988 and voids your warranty. Always use JLR's Pathfinder diagnostics for accurate fault codes.

1. AdBlue System & Emissions System Malfunctions

Symptoms: "Emissions System Malfunction" warning, AdBlue warning, MOT failure (active DTCs like P204F or P20EE), reduced power.

Typical mileage: Any mileage — can affect low-mileage examples.

Repair cost: £500–£2,000 (AdBlue dosing valve replacement, injector cleaning, SCR system repair).

Replacement cost: N/A — repair only; ignoring emissions warnings will result in MOT failure.

🟠 Check - book inspection urgently if warnings appear.

Our recommendation:

2. Coolant Leaks

Symptoms: Coolant level low warning, visible coolant puddles under the vehicle, overheating risk, engine warning light.

Typical mileage: Any mileage — reported on vehicles as new as 3 months old.

Repair cost: £500–£2,000 (coolant crossover pipe replacement, hose repair).

Replacement cost: N/A — repair only; if ignored, can lead to engine failure.

🔴 Immediate - book inspection urgently if coolant level drops.

Our recommendation:

Coolant leaks have been reported on P510e vehicles, including a "massive coolant leak" on a 3-month-old example. The coolant crossover pipe on supercharged V6 and V8 JLR engines is known to fail as vehicles age. Early detection and repair could save an engine. If you see any coolant level warnings, have the system inspected immediately.

3. Hybrid Battery & Electrical System Issues

Symptoms: "Battery not available" warning, reduced EV range, charging issues, cold weather performance degradation.

Typical mileage: 20,000–60,000 miles.

Repair cost: £1,000–£3,000 (BECM repair); £8,000–£15,000 (battery replacement).

Replacement cost: N/A — repair only; battery is a wear item.

🟡 Monitor - book inspection soon if range noticeably drops.

Our recommendation:

The 38.2kWh battery has a six-year warranty. A recall (R/2026/078) has been issued for certain 2023 model year PHEV vehicles relating to hybrid battery capacity. Cold weather can also affect battery performance. To maximise battery life, avoid frequent rapid charging, keep the battery between 20% and 80% for daily use, and ensure the cooling system is maintained.

Buying This P510e? Check These First

Buy If

Full service history with JLR-approved PHEV maintenance
AdBlue system checked and no emissions warnings
Battery health report showing >85% state of health
Recall R/2026/078 completed (if applicable)

Avoid If

AdBlue or emissions warnings — potential dosing valve or SCR issues
Coolant leaks — potential cooling system failure
"Battery not available" or charging warnings — potential BECM issue
No service history — PHEV systems are complex and unforgiving of neglect

Closing Verdict

The P510e is a complex, high-tech luxury SUV that offers impressive performance (510PS, 0-60mph in 5.4 seconds) and EV range (up to 70 miles). However, it comes with PHEV-specific vulnerabilities — AdBlue system issues, coolant leaks, and battery concerns. A £10,000 reconditioned engine on a Range Rover Sport valued at £70,000 is just 14% of the car's value — well worth it. However, always factor in potential battery costs (£8,000–£15,000) when assessing a used example.
