How much does a Range Rover Sport P510e engine replacement cost-

A complete rebuilt Range Rover Sport P510e engine typically costs between £6,500 and £9,500 for supply only [ESTIMATED - using 306PS 3.0 Ingenium Petrol as proxy]. Used units start from around £2,500. Reconditioned units range from £4,500 to £7,500. Prices vary based on the specific AJ300E engine code and supplier.

Can the Range Rover Sport P510e run on just the petrol engine if the hybrid system fails-

Yes, the Range Rover Sport P510e is designed to default to the 3.0L petrol engine if the high-voltage battery or electric drive unit fails. The vehicle will enter a reduced-power "limp mode" to protect the drivetrain. Fuel economy will drop significantly as the heavy battery is carried without electric assistance. A full diagnostic is required to isolate whether the fault lies with the combustion engine or the hybrid components.

What are the signs of thermal management failure in a Range Rover Sport P510e-

Early warning signs include a sudden reduction in electric-only driving range or slower-than-normal AC charging speeds. Dashboard warnings for "High Voltage System Fault" or "Engine Cooling System". The vehicle may refuse to accept a charge or abruptly switch to petrol-only mode. Unusual humming or whining from the rear electric drive unit.

Is it worth replacing the engine in a Range Rover Sport P510e-

Yes, absolutely. The Range Rover Sport P510e is a high-value luxury SUV with current market values ranging from £65,000 to over £95,000 [THIRD-PARTY]. A rebuilt engine cost is a small fraction of the vehicle's total value. It preserves the car's performance, refinement, and resale value. Upgraded rebuilt units address known factory thermal and integration weaknesses.

How long does a Range Rover Sport P510e engine supply and fit take-

A professional Range Rover Sport P510e engine replacement typically takes 4 to 6 working days due to the complexity of the hybrid system. Removal and preparation of the old unit takes 1-2 days. Fitting, high-voltage system calibration, and software integration of the new rebuilt engine takes 2-4 days. Nationwide collection and delivery are arranged by the specialist.

Common Problems

Range Rover Sport P510e Engine Problems Repair Cost vs Replacement

The 3.0L Ingenium straight-six plug-in hybrid in the Range Rover Sport P510e is a highly advanced powertrain. While offering exceptional efficiency and torque, its complex thermal management and high-voltage architecture require precise, specialist maintenance. Rebuilt engines through EnginesMarket include upgraded components addressing original failure points, backed by a minimum 12-month unlimited-mileage warranty.

Common failure points and repair options

Thermal Management & High-Voltage Battery Cooling Issues

Affected: Range Rover Sport P510e (AJ300E, 2022-present)
Typical failure mileage: 40,000-80,000 miles (emerging pattern in early L461 models)

Root cause

The complex thermal management system, which cools both the combustion engine and the high-voltage battery pack, can develop pump or sensor faults. This leads to reduced charging speeds, limp mode activation, or restricted electric-only range to protect the battery from overheating.

Repair options

Repair tier	Dealer price	Specialist price
Preventative Thermal System Service	£800-£1,500	£500-£900
Full Replacement - rebuilt/reconditioned engine	£9,000-£13,000	£6,500-£9,500 [ESTIMATED - using 306PS 3.0 Ingenium Petrol as proxy]

Our recommendation

Proactive inspection of the thermal management system at the first sign of charging slowdowns or warning lights is a highly recommended, low-cost preventative measure. If the combustion engine has suffered secondary damage from overheating, a full rebuilt engine replacement is the safest and most reliable solution.

Electric Drive Unit Bearing Wear & Software Glitches

Affected: Range Rover Sport P510e (AJ300E, 2022-present)
Typical failure mileage: 50,000-90,000 miles

Root cause

The rear-mounted electric drive unit can develop bearing wear over time, manifesting as a high-pitched whine. Additionally, software integration glitches between the combustion engine and electric motor can cause abrupt drive mode transitions or false fault codes.

Repair options

Repair tier	Dealer price	Specialist price
Software Update & Drive Unit Inspection	£300-£600	£150-£350
Full Replacement - rebuilt/reconditioned engine	£9,000-£13,000	£6,500-£9,500 [ESTIMATED - using 306PS 3.0 Ingenium Petrol as proxy]

Our recommendation

If caught early, a specialist software update and drive unit inspection is the most cost-effective route. However, if the electric drive unit has seized or caused catastrophic failure, investing in a fully rebuilt unit with verified hybrid integration is the only way to guarantee long-term reliability.
