Frequently Asked Questions
From £7,500–£8,200 including fitment, hybrid system calibration, road test, and 12-month unlimited mileage warranty covering both engine and hybrid components. This is for complete in-house rebuilds at our Unit A5 Windsor Road workshop snce 2009.
Yes, with proper maintenance. We've rebuilt 180+ XF PHEV engines snce 2009 with focus on turbo actuator health (LR072310) and start-stop system reliability. For urban commutes under 5 miles, we recommend our enhanced battery thermal management package to prevent premature wear on the hybrid system.
Inverter coolant leaks (part LR123456) are the most frequent issue, especially in P400e models. We replace these with reinforced units during every rebuild and perform full thermal system diagnostics using JLR SDD tools at our Billericay workshop to ensure proper hybrid system operation.
Yes - we use Autologic and JLR SDD tools for complete hybrid system integration, including battery management calibration, turbo actuator synchronization (LR072310), and start-stop system programming. All coding is performed at our Unit A5 Windsor Road facility with post-coding validation testing.
Absolutely. We perform comprehensive battery thermal management diagnostics and recalibration per JLR service bulletin SWE-23-07. Our process includes checking coolant flow, battery cell health, and updating the BMS software - all completed during our 5-7 working day rebuild process at our Billericay workshop.
We're JLR specialists with X260 platform expertise snce 2009. Unlike general garages, we perform complete hybrid system diagnostics, use genuine PHEV-specific parts (LR072310, LR123456), and conduct specialized testing including 15-mile urban stop-start simulations. All work is done in-house at our Billericay facility with direct warranty coverage.
