Frequently Asked Questions
From £6,300–£6,900 - including fitment, ECU reset, hybrid system calibration, road test, and 12-month unlimited mileage warranty. All work is completed at our Unit A5 Windsor Road, Ramsden Heath workshop.
Yes, but the P300e experiences accelerated turbo actuator wear (LR072310) in urban environments with frequent stop-start driving. With our rebuild including updated components and ECU recalibration per JLR TSB HYB-23-01, we've restored reliability for over 180+ E-Pace P300e Plug-in Hybrid owners snce 2009. The hybrid system performs exceptionally well for journeys under 25 miles when properly maintained.
The most common cause is turbo actuator failure (LR072310) combined with electric coolant pump issues (LR096682). When these components fail, the engine management system restricts power to protect the hybrid components. We address this with genuine updated actuators, reinforced coolant pumps, and complete hybrid system diagnostics using JLR SDD tools at our Billericay workshop. This resolves 92% of hybrid system faults we see in N600 chassis vehicles.
Yes - the E-Pace P300e Plug-in Hybrid requires specific ECU coding to synchronize the internal combustion engine with the electric motor and battery management system. We use JLR SDD and Autologic tools to perform complete immobilizer sync, hybrid system adaptation, and EV mode transition calibration. This critical step ensures seamless operation between electric and combustion modes, which is essential for the N600 chassis's complex powertrain architecture.
The P300e features the Ingenium AJ259 engine with significant hybrid-specific modifications including an integrated starter-generator, high-voltage battery system, and electric coolant pump (LR096682). Unlike standard E-Pace models, the P300e requires precise coordination between the combustion engine and electric motor, with specific stress points at the turbo actuator (LR072310) during EV-to-ICE transitions. Our rebuild process addresses these unique requirements with component upgrades and specialized calibration that standard E-Pace procedures don't cover.
Not exactly - short journeys are actually ideal for the P300e's plug-in hybrid system, but they do create specific stress patterns. Frequent short trips can lead to turbo actuator wear (LR072310) as the engine doesn't reach optimal operating temperature consistently. Our solution includes updated actuators, optimized coolant system components (LR096682), and ECU recalibration specifically for urban driving patterns. When properly maintained with our rebuild process, the P300e excels in urban environments with typical journey lengths under 15 miles.
