Common Failure
The Battery Energy Control Module (BECM) is a known failure point on Range Rover Sport PHEV models including the P440e, causing hybrid system faults, charging failure, and loss of electric drive. Timing chain tensioner wear has also been reported on Ingenium petrol engines, with symptoms including rattling noise on startup and rough running.
The Range Rover Sport P440e uses the AJ300 3.0-litre Ingenium I6 petrol engine paired with a 105kW electric motor and 38.2kWh battery. While the Ingenium petrol six-cylinder is more reliable than its diesel siblings, PHEV-specific components introduce additional failure points. Rebuilt AJ300 engines through EnginesMarket include upgraded components addressing the original failure points, plus a minimum 12-month unlimited-mileage warranty.

Root Cause
The Battery Energy Control Module (BECM) controls the high-voltage battery charging process and hybrid system operation. Internal electronic failure prevents the vehicle from charging, entering 'Ready' mode, or using electric drive.

Vehicle Value Check
Vehicle Value Check
Apply this UK-wide decision framework: - Vehicle worth under ~£5,000: repair or used engine typically makes more sense than a full rebuilt unit. - Vehicle worth ~£5,000-£8,000: evaluate both; reconditioned is viable if keeping the car 2+ years. - Vehicle worth ~£8,000-£15,000: reconditioned/rebuilt usually justifies the premium via warranty and reliability. - Vehicle worth £15,000+: replacement cost is typically small relative to vehicle value.
Our Recommendation
Our Recommendation
If your P440e displays a 'Hybrid System Fault' warning or refuses to charge, have the BECM diagnosed before assuming engine replacement is needed. BECM replacement is significantly cheaper than a full engine swap. However, if the engine has suffered timing chain failure or internal damage from running without hybrid assistance, a rebuilt AJ300 unit with upgraded components and 12-month warranty is the sensible long-term solution.
Don't Let Engine Failure Write Off Your Range Rover Sport P440e
The Range Rover Sport P440e is a complex, high-value PHEV - but engine failure doesn't have to mean the end of the road. Whether it's BECM failure, timing chain wear, or a full rebuild, EnginesMarket connects you with vetted UK specialists who know the AJ300 Ingenium I6 inside out. Every rebuilt engine comes with a minimum 12-month unlimited-mileage warranty, upgraded components addressing the original failure points, and nationwide delivery options.

- Used AJ300 engines: £2,800-£4,500

Question 2What are the signs of BECM failure in a Range Rover Sport P440e-
The Battery Energy Control Module (BECM) is a known weak point on P440e models. Common symptoms include:
- 'Hybrid System Fault' warning on the dashboard
- Vehicle refuses to charge or charging stops prematurely
- Car won't enter 'Ready' mode or start

- Zero electric range - vehicle runs on petrol only
Question 3Is it worth replacing the engine in a Range Rover Sport P440e-
Yes - a 2022-2024 Range Rover Sport P440e typically holds £55,000-£90,000 of value. Even a full engine replacement at £7,500-£9,500 represents a small fraction of the vehicle's worth. For older examples approaching £40,000-£50,000, the replacement still makes financial sense if the rest of the vehicle is in good condition.
- Newer P440e (2022-2024): replacement strongly recommended
- Higher-mileage examples: weigh against overall vehicle condition

A full Range Rover Sport P440e engine replacement typically takes 5-10 working days:
- Engine removal and installation: 2-3 days
- Hybrid system re-calibration and testing: 1-2 days
- Total turnaround: 5-10 days depending on parts availability
Question 5What's the difference between the P440e and P510e engines-
Both are 3.0-litre Ingenium I6 PHEV engines in the L461 Range Rover Sport, but:
- P440e: 440PS (434bhp) combined output
- P510e: 503bhp combined output - higher tune of the same engine
- Both use the same AJ300 engine block and 105kW electric motor
- P510e has higher boost and revised ECU mapping
Question 6Does the Range Rover Sport P440e have timing chain problems-
Timing chain tensioner wear has been reported on Ingenium petrol engines, including the AJ300 in the P440e. Symptoms include rattling noise on cold start, rough running, and reduced performance.
- Preventative replacement at 60,000-80,000 miles recommended
- Cost: £1,800-£3,000 at a specialist
- Ignoring it can lead to catastrophic engine failure
