Engine Diagnostics
We provide advanced engine diagnostics designed to accurately identify faults, warning lights and drivability issues across all modern petrol and diesel vehicles.
Why Choose Professional Diagnostics?
Window tinting is about far more than appearance. Many customers are surprised by how much cooler and more comfortable their vehicle feels after a professional tint installation.
Fault Detection
Identify the exact cause of warning lights, fault codes and drivability issues using professional-grade diagnostic equipment.
Save Time & Money
Avoid unnecessary parts replacement by finding the real issue first time, rather than guessing and swapping components.
Live Data Analysis
Read live sensor data while the engine runs to catch intermittent faults that standard code readers often miss.
Limp Mode & Drivability
Resolve loss of power, rough running, stalling and limp mode issues with a clear systems-first diagnosis.
Clear Explanations
Understand exactly what's wrong with your vehicle in plain language, with no confusing jargon or upselling.
Pre-Purchase Checks
Considering buying a used vehicle? A full diagnostic check gives you peace of mind before you commit.
A Systems-First Approach
A quality diagnosis is only as good as the engineer behind it. Every vehicle is thoroughly checked using professional tools and a logical, systems-first approach to find the true root cause.
"No guesswork. No part-swapping. Just an honest answer about what's wrong and what it'll take to fix it."

What We Check
Every System, Fully Checked, Explained.
A complete diagnostic check covers every major system in your vehicle, giving you a clear picture of its overall health and any underlying issues that might not be obvious yet.
Engine management, fuel system, emissions, transmission and ABS — every fault code is read, cross-referenced with live data and checked against your vehicle's specific history.
Once the scan is complete, we explain every finding in plain language, outline what's urgent versus what can wait, and give you a clear plan for next steps.
