Our Process – Step by Step
Pre‑diagnostic & backup
We run a full JLR diagnostic scan, clear faults, and back up the current ECU settings to ensure a clean baseline.
Disassembly
Front bumper, radiator, intercooler, and often the front subframe are removed to access the engine bay.
Detach ancillaries
All electrical connectors, exhaust bolts, coolant hoses, and engine mounts are systematically disconnected.
Engine removal
Using a professional engine hoist (322 kg+ capacity), the old unit is lifted out – or the subframe is lowered as one assembly.
Component transfer
All reusable sensors, manifolds, and brackets are transferred to the replacement engine.
Reinstallation
The replacement engine is fitted, aligned, and all connections are re‑made with factory torque settings.
ECU coding & synchronisation
Using JLR SDD / Pathfinder, we code the ECU to match the new engine’s parameters and your vehicle’s VIN. Immobiliser synchronisation is also performed.
Validation & road test
Every replacement undergoes a full road‑test to confirm all systems operate correctly before handover.

Frequently Asked Questions
What’s included in an engine replacement?
Our service includes removal of the old engine, supply of a correctly matched replacement unit, fitting, transfer of all reusable ancillaries, JLR ECU coding and immobiliser synchronisation, and a full road‑test validation. We also include a 12‑month unlimited‑mileage warranty.
How long does a Jaguar engine replacement take?
Typical workshop time is between 14 and 30 hours depending on the model and engine type. We’ll give you a clear schedule when we quote – most replacements are completed within one working week.
Will the replacement engine be coded to my car?
Yes – we always perform dealer‑level ECU coding to match the new engine’s parameters to your vehicle’s VIN. This ensures correct operation and full integration with the immobiliser, transmission, and other modules.
Do you source the replacement engine, or do I supply it?
We supply the replacement unit for you – we source engines from reputable suppliers and ensure they are the exact match for your vehicle. We never fit customer‑supplied engines because we can’t guarantee their condition or compatibility.
Can you recover my Jaguar if it’s not driveable?
Absolutely – we offer nationwide engine recovery starting from £70. Just call us and we’ll arrange collection to our workshop.
