Frequently Asked Questions
The cost for rebuilding the P400e Phev's internal combustion engine starts from £7,650 and can go up to £8,150, depending on the condition of hybrid components like the motor control unit. This includes comprehensive inspection, machining, new parts, and a 12-month unlimited mileage warranty.
Yes, absolutely. Our rebuilds address the common weak points like coolant pump failures and integrate seamlessly with the hybrid system. Post-rebuild, customers report excellent reliability and improved efficiency. We've completed 45+ P400e Phev engine restorations snce 2009.
Significantly. The P400e Phev shares the base Ingenium 2.0L engine block but includes complex hybrid integration components like the electric motor, high-voltage battery pack, and dedicated control modules. Our rebuild process specifically addresses these unique systems alongside the ICE.
Yes, ECU coding and calibration are essential for the P400e Phev. The engine control unit must be programmed to recognize the rebuilt components and ensure proper communication and integration with the hybrid system. We use JLR SDD tools for this.
Yes, our workshop is equipped to perform diagnostics on the P400e Phev's high-voltage battery pack during the rebuild process. We can identify degraded cells and replace them, ensuring optimal hybrid system performance alongside the newly rebuilt ICE.
No, a correctly rebuilt ICE engine will not affect the electric-only range. The range is determined by the battery pack capacity and the electric motor's efficiency, which are independent of the ICE. However, a well-running engine improves overall system efficiency.
