Three other garages couldn't find the fault. RR Engine Works found an injector issue within an hour using their diagnostic equipment. Absolute professionals.

ENGINEDIAGNOSTICS
Advanced engine diagnostics for warning lights, misfires, smoke, power loss, and mechanical faults across Range Rover and Land Rover platforms.
Detailed Overview
Advanced Diagnostics, Accurate Results
Modern Range Rover engines are among the most technologically advanced in the automotive world. When a fault light appears or performance drops, guesswork simply isn't an option. Our engineers use Land Rover-approved diagnostic tools including Autologic and SDD (Symptom Driven Diagnostics) to read live data, fault codes, and module health across every system.
We go beyond simply reading fault codes — our diagnostics process includes a full engine health check, fuel trim analysis, injector balance rate testing, and compression assessment. This gives us a complete picture of your engine's condition before any work begins.
Our transparent reporting means you'll receive a full written diagnostic report with prioritised findings and recommended actions. We never recommend unnecessary work. Based in Grays, Essex, we serve Range Rover owners across Thurrock, Dartford, Romford, and Central London.
DIAGNOSTIC ACCURACY GUARANTEE
We back every diagnostic session with a written report and a promise: if we can't find the fault, you don't pay for a repair.
WHAT'S INCLUDED:
Full OBD scan, live data analysis, fuel system check, and a written health report are all included in the standard diagnostic fee.
ADVANCED DIAGNOSTICS PACKAGE:
Our extended package adds injector testing, compression analysis, and a full module network scan — ideal for complex intermittent faults.

Specialist Range Rover And Land Rover Repair Process
Specialist JLR Repair WorkflowFROM DIAGNOSIS TO HANDOVER
Our workshop process is built to move Range Rover and Land Rover owners from confirmed diagnosis to the right repair route with clearer planning, correct parts selection, and dependable final checks.
We begin by identifying the real cause of the fault so repair, rebuild, or replacement decisions are based on evidence instead of assumptions.
The vehicle and required parts are then matched carefully to the job so compatibility, fitment, and supporting system needs are understood early.
Major work is completed with workshop-led checks, structured installation standards, and attention to the common weak points seen on JLR platforms.
Before handover, we validate the repair outcome so customers leave with a clearer route back to reliable performance and everyday drivability.

PRECISION REBUILDSUK’S LEADING AUTHORITY IN RANGE ROVER ENGINE RESTORATION
Range Rover Garage is the UK’s leading independent authority in Range Rover engine restoration, delivering dealership-level engineering precision from our specialist facility in Grays, Essex.
We restore and rebuild Land Rover and Range Rover engines using OEM specifications, advanced machining equipment, and factory-grade diagnostic systems to ensure maximum performance and reliability.
Every engine undergoes a strict 200+ point inspection process, including compression testing, timing calibration, and full internal component replacement where required.
Our rebuild process is designed to restore engines to near-factory condition while often improving durability beyond original manufacturer standards.
NATIONWIDE ENGINE REBUILD SUPPORT
We proudly support customers across London, Essex, Kent, Birmingham, and nationwide with premium engine rebuild solutions.
Only genuine OEM Land Rover parts and reinforced internal components are used to eliminate common factory weaknesses found in TDV6, SDV6, and V8 platforms.
Each engine is fully dismantled, chemically cleaned, re-machined, and reassembled under controlled torque specifications.
All rebuilds are dyno-tested and backed by warranty coverage for complete customer peace of mind.
DIAGNOSTIC MASTERYENGINE DIAGNOSTICS FOR WARNING LIGHTS, MISFIRES, AND POWER LOSS
We investigate engine warning lights, poor running, misfires, power loss, timing issues, smoke, and mechanical noise across Range Rover and Land Rover vehicles.
Accurate diagnosis helps identify whether the fault is electronic, mechanical, fuel-related, turbo-related, or part of a deeper internal engine issue.
This reduces unnecessary parts replacement and helps customers move toward the correct repair decision much faster.
MODEL-SPECIFIC TESTING AND SMARTER ENGINE REPAIR DECISIONS
Our diagnostic process is built around the fault patterns seen on JLR engine families instead of relying on generic code reading alone.
We use testing and inspection results to judge whether the engine needs targeted repair, supporting work, or escalation into rebuild or replacement planning.
That leads to more reliable repair outcomes, better workshop accountability, and clearer advice for the owner.
