Decade of Expertise
L405 Specialists
The Team Behind Every L405 Engine Rebuild
The L405 spans a decade of engine development, from the original TDV6 through to the later Ingenium four- and six-cylinder units, and our technicians have worked on every variant as they've come through the workshop door. That breadth of experience means faster, more accurate diagnosis regardless of which engine your Range Rover carries.
We hold reconditioned and used TDV6, SDV6, SDV8 and 5.0 V8 units ready for fitting, alongside strong supplier relationships for the newer Ingenium range. Every rebuild follows manufacturer torque and timing specifications, with post-repair testing before the vehicle is signed off.
Whatever the fault, you'll get a clear explanation of what's gone wrong, what it will cost to fix, and what your realistic options are.
Recognising the Common L405 Engine Faults
Timing chain wear is the fault we see most often on early SDV6 and SDV8 engines, typically announcing itself through rattling on cold start or fault codes relating to chain stretch. Left unaddressed, it can lead to far more serious internal damage.
Later Ingenium-engined models bring a different set of concerns, including timing belt-in-oil designs and injector issues that require specific diagnostic knowledge to isolate correctly. We stay current with the relevant technical service bulletins for each engine generation.
Catching these issues early, rather than waiting for a warning light to become a breakdown, is usually what separates a straightforward repair from an expensive rebuild.
Targeted Diagnostics
Technical Bulletins
An Engine Repair That's Built to Last
Every L405 that comes through our workshop is treated according to its specific engine generation, not a one-size-fits-all process. That distinction matters, because a fix that works on an early TDV6 won't necessarily suit a later Ingenium unit.
Rebuilds are carried out with new or reconditioned components throughout, torque-checked to specification, and tested before the car leaves. Replacement engines are matched, verified and fitted with the same care, so performance and reliability are restored properly.
The outcome is a Range Rover that drives the way it should, with a warranty behind the work and a specialist workshop on hand if you ever need us again.

Explore Article→Why Independent L405 Specialists Make the Difference
Main dealer labour rates and parts pricing on L405-generation engine work can be considerable, and general garages without Land Rover-specific diagnostic experience often struggle to pinpoint faults on these engines correctly the first time.
Because we work on nothing but Land Rover and Jaguar engines, our technicians see far more TDV6, SDV6, SDV8 and Ingenium units than most workshops ever will. That volume of hands-on experience means faster diagnosis, fewer guesswork repairs, and a clearer picture of whether a rebuild or replacement makes better financial sense.
Every quote is provided in writing before work begins, so you always know exactly what you're paying for.
