Frequently Asked Questions
From £7,800 - including fitment, ECU reset, road test, and 12-month warranty. Our pricing for the P400 Ingenium AJ300P engine reflects the complexity of the 48V MHEV system and includes genuine Jaguar parts like the LR072310 turbo actuator. All work is performed at our Unit A5 Windsor Road, Ramsden Heath, Billericay workshop with transparent, all-inclusive pricing.
Yes, with proper maintenance. The P400's 48V MHEV system significantly improves stop-start reliability compared to earlier models, but urban driving can stress the turbo actuator (LR072310) and timing chain system. We've rebuilt over 185 F‑PACE P400 R‑Dynamic S (MHEV) engines since 2009, implementing reinforced timing chain guides (LR096682) and updated turbo actuators to address these specific urban driving concerns. Our rebuilds include MHEV system calibration for optimal stop-start performance.
The most common issue is turbo actuator failure (LR072310), particularly in urban driving conditions where the MHEV system places additional load on the turbocharger. This manifests as sudden power loss during highway driving. Our solution includes installing the updated turbo actuator LR072310 with proper ECU recalibration per JLR service bulletin SWE-23-09. We also inspect the MHEV system thoroughly as part of our standard rebuild process at our Billericay workshop.
Yes, diagnosing F‑PACE P400 R‑Dynamic S (MHEV) issues requires specialized equipment. We use both Autologic and JLR SDD diagnostic tools specifically configured for the 48V MHEV system. These tools allow us to properly assess the turbo actuator (LR072310), timing chain system (LR096682), and the complex energy regeneration system. Our technicians at Unit A5 Windsor Road have completed Jaguar's advanced MHEV training programs and follow JLR service bulletins like TSB-22-015 for accurate diagnosis.
Absolutely. Our complete rebuild process for the F‑PACE P400 R‑Dynamic S (MHEV) includes comprehensive MHEV system diagnostics and recalibration. We test the 48V battery management system, verify energy regeneration functionality, and perform software updates as needed per JLR TSB-22-015. Unlike some competitors, we don't just replace engine components - we ensure the entire powertrain system, including the MHEV integration with the Ingenium AJ300P engine, works seamlessly. All MHEV diagnostics and repairs are performed at our Billericay facility.
Our F‑PACE P400 R‑Dynamic S (MHEV) rebuild specifically addresses the unique challenges of the 48V MHEV system. We include reinforced timing chain guides (LR096682), updated turbo actuators (LR072310), and comprehensive MHEV system diagnostics that standard rebuilds don't cover. Our validation process includes a specialized 15-mile road test that verifies MHEV performance under real-world conditions. Every rebuild at our Unit A5 Windsor Road workshop follows JLR service bulletins specific to the P400 Ingenium engine, ensuring proper integration between the combustion engine and MHEV components.
