Our In-House Rebuild Process
Every SVAutobiography Dynamic engine undergoes our 5-step rebuild process:
Diagnosis
Scan for supercharger boost errors, turbo actuator codes, timing chain faults specific to SVAutobiography Dynamic performance modes
Performance Mode Diagnostics
- Supercharger boost control check
- Turbo actuator health assessment
- Intake carbon buildup evaluation
Metrology
Measure cylinder wear, bearing clearances (<0.05mm tolerance) - critical for SVAutobiography Dynamic high-performance applications
Precision Standards
- Crankshaft runout (<0.05mm)
- Bearing clearance measurement
- Cylinder bore wear assessment
Machining
Block honing, head skimming - all done on-site at our Billericay facility
On-Site Facilities

Frequently Asked Questions
From £7,850 - including fitment, ECU reset, road test, and 12-month warranty. The P400 requires specialized supercharger rebuild procedures and Dynamic mode recalibration at our Billericay workshop.
Yes - with our updated turbo actuators LR072310 and ECU recalibration for high-performance use. We've rebuilt over 75 D300 SVAutobiography Dynamic engines since 2017, specifically addressing Sport mode stress points.
The base engine is identical, but SVAutobiography Dynamic models require specialized ECU mapping for Dynamic mode functionality and enhanced performance characteristics. Our rebuilds include these trim-specific calibrations.
Yes - we use Autologic and JLR SDD for full Dynamic mode activation, performance parameter programming, and integration with advanced driver assistance systems at our Billericay facility.
SVAutobiography Dynamic models require additional attention to performance components like superchargers in P400, twin-turbo systems in D300, and advanced MHEV integration. ECU recalibration for Dynamic mode functionality is also essential.
We focus on OEM-spec reliability, but can install reinforced components like upgraded supercharger internals or improved turbo actuators LR072310 to enhance durability for performance driving.
