What Is a Diagnostic Check?
Modern vehicles rely on complex electronic systems to monitor performance and safety. When something goes wrong, your car’s onboard computer stores fault codes that can be read using specialist equipment.
A diagnostic check allows us to:
- Read and interpret fault codes
- Identify issues with the engine, brakes, transmission or electronics
- Check sensor performance and system health
- Recommend the right repair or reset
It’s a quick and effective way to understand what’s happening under the bonnet—especially when warning lights appear or your car isn’t driving as it should.
Common Signs You Need a Diagnostic Check
Not sure if you need one? Here are a few signs your car might benefit from a diagnostic:
- Dashboard warning lights (engine, ABS, airbag, etc.)
- Loss of power or poor fuel efficiency
- Unusual noises or vibrations
- Electrical faults (lights, windows, central locking)
- Trouble starting or stalling
If you notice any of these, it’s best to get your car checked sooner rather than later. Ignoring faults can lead to more serious damage and costly repairs.
