What is vehicle diagnostics?

Modern cars rely heavily on technology, which is why we use advanced tools, software, and manufacturer guidelines to identify any issues your vehicle might have. Many people confuse "vehicle diagnostics" with "engine diagnostics." Engine diagnostics focus specifically on problems related to your engine, fuel system, and exhaust emissions, while vehicle diagnostics cover the entire car.

How do vehicle diagnostics work?

Before modern technology, cars had simple warning lights for basic problems. Today, we use On-Board Diagnostics (OBD) systems that constantly monitor your car. A handheld scanner reads Diagnostic Trouble Codes (DTCs) when something goes wrong. While these codes don’t tell us exactly what the issue is, they help us pinpoint the area that needs attention.

Common error codes

Our technicians use standardised tools to interpret error codes, diagnose the issue, and recommend necessary repairs.

P01xx: Indicates a fuel system issue.
P03xx: Points to a problem with your car’s emission control systems.
P05xx: Signals a malfunction in the Idle Air Control (IAC) actuator, which controls the engine’s idle speed.
