How It Works

Vehicle diagnostics is a digital check-up for your car. Using an OBD scanner, we detect faults, monitor system health, and interpret dashboard warnings, helping you catch issues early and drive with confidence.

What Is Vehicle Diagnostics?

Vehicle diagnostics is the process of digitally analysing your car’s systems to detect faults or malfunctions. Using specialist diagnostic equipment, our technicians connect to your vehicle’s OBD (On-Board Diagnostics) port to:

• Read stored and live fault codes

• Monitor real-time performance data

• Pinpoint issues in key systems like the engine, transmission, brakes, and electronics

This method ensures accurate fault detection without unnecessary guesswork, helping us recommend the right repairs from the start.

Why You Might Need a Diagnostic Check

You should book a vehicle diagnostic service if you notice:

• Dashboard warning lights (engine light, ABS, airbag, etc.)

• Unusual noises or vibrations

• Loss of power or poor performance

• Increased fuel consumption

• Electrical problems, such as faulty lights or controls

Even if no warning light appears, diagnostics can still uncover hidden issues before they become costly repairs.
