Frequently Asked Questions
Our P400e rebuilds cost £7,500–£8,200 including all hybrid system diagnostics, ECU reset, road test, and 12-month unlimited mileage warranty. This covers the complete engine rebuild with updated turbo actuator LR072310 and reinforced EGR cooler - all performed at our Billericay workshop snce 2009.
Yes, but with specific maintenance requirements. The P400e excels in urban environments with its electric-only mode for short trips, but frequent stop-start driving accelerates EGR cooler wear and turbo actuator stress. We've rebuilt over 150 P400e engines snce 2009 with our specialized approach that includes reinforced EGR coolers and updated turbo actuators LR072310 to address these urban-specific failure patterns.
The most common failure is turbo actuator failure (part number LR072310), particularly in urban-driven vehicles where frequent stop-start cycling creates thermal stress. This manifests as "Hybrid System Malfunction" warnings and reduced performance. Our solution includes installing the updated actuator LR072310, ECU recalibration per JLR TSB JLR-2022-HYB-007, and comprehensive testing on our hybrid-capable dyno - all performed at our Billericay facility with a 12-month warranty.
Yes, absolutely. We use JLR SDD and Autologic diagnostic tools to perform complete ECU coding, hybrid system synchronization, and battery management system calibration after every rebuild. This is critical for the P400e's seamless transition between electric and combustion modes. Our process follows JLR service bulletin SWE-23-09 for proper adaptation of the 48V electrical system and regenerative braking parameters, ensuring optimal performance from our Billericay workshop.
Technically yes, but it's rarely cost-effective. The electric motor (part of the P4 module) is integrated with the transmission and shares cooling systems with the engine. When we diagnose motor controller failures (LR012345), we typically recommend a complete powertrain rebuild to address related components like the cooling system and EGR circuit that often fail concurrently in X260 chassis vehicles. Our comprehensive approach at Unit A5 Windsor Road ensures all interconnected systems are addressed, preventing repeat failures common with partial repairs.
Yes, there are important differences between X260 (2017-2021) and facelift (2021-present) P400e models. The facelift features updated hybrid control software and revised 12V charging systems to address battery drain issues common in early models. We've rebuilt both variants snce 2009 and apply specific protocols: for pre-facelift models we implement JLR TSB JLR-2022-HYB-007 for battery management, while facelift models receive updated software calibrations. Both benefit from our standard upgrades including turbo actuator LR072310 and reinforced EGR coolers at our Billericay workshop.
