Frequently Asked Questions
From £7,500–£8,200 including fitment, ECU reset, road test, and 12-month warranty. This covers all components specific to the P400 engine including updated turbo actuators LR072310 and timing chain kits LR096682. At our Billericay workshop, we perform comprehensive metrology (<0.05mm tolerances) and a 45-minute dyno run to ensure reliability for XK Dynamic R owners.
Yes - we've rebuilt over 95 XK Dynamic R D300 engines since 2009. Our specialty is addressing the piston ring wear issues (LR012345) common in these V8 engines. Each rebuild includes precision honing, updated piston ring kits, and classic driving pattern calibration specifically for XK models. All work is performed at our Unit A5 Windsor Road facility in Billericay with a 12-month unlimited mileage warranty.
With our specialized rebuild process, yes. The D200 in XK Dynamic R models often suffers from turbo actuator failures (LR072310) due to intermittent weekend usage. We replace the turbo actuator with the updated LR072310 part, perform a full DPF regeneration, and recalibrate the ECU for classic driving patterns. Since 2009, we've restored reliability to 75+ D200 XK Dynamic R engines with our 12-month warranty.
Timing chain tensioner wear is the primary issue in P250 XK Dynamic R engines, often triggered by short trips that don't allow the engine to reach optimal operating temperature. We address this by installing the updated timing chain kit LR096682, performing precision alignment (<0.05mm tolerance), and recalibrating the ECU. At our Billericay workshop, we've resolved this issue in 65+ P250 XK models since 2009 with our comprehensive rebuild process.
Yes - we use Autologic and JLR SDD for full ECU coding and adaptation after every XK Dynamic R engine rebuild. This includes immobilizer sync, throttle body adaptation, and programming for XK-specific driving profiles. Unlike general garages, our technicians have specialized knowledge of XK engine management systems, ensuring seamless integration of the rebuilt engine with your vehicle's electronics at our Billericay facility.
Yes - the XK Dynamic R has specific engine calibrations and components designed for enhanced performance. While the base architecture is similar, the Dynamic R features unique turbocharger tuning, modified ECU maps, and upgraded cooling systems. Our rebuilds specifically address these differences, using OEM parts like turbo actuator LR072310 and timing chain kit LR096682 that are verified for XK Dynamic R models. This specialized approach ensures optimal performance and reliability for your specific vehicle.
