Warning Signs You Might Need a Diagnostic Check
If your car isn’t performing as it should, a diagnostic check can help identify the issue before it becomes a costly repair. We recommend booking a diagnostic if you notice any of the following:
- Dashboard warning lights – such as the check engine, ABS, or airbag light staying on
- Unusual noises – knocking, grinding, or squealing sounds from the engine or brakes
- Poor fuel efficiency – a sudden drop in miles per gallon could indicate engine or sensor issues
- Difficulty starting – slow or failed starts may point to battery, ignition, or fuel system faults
- Loss of power – hesitation or sluggish acceleration can signal problems with the engine or transmission
- Excessive exhaust smoke – blue, black, or white smoke may indicate internal engine issues
- Electrical faults – malfunctioning lights, windows, or dashboard displays
- If you’re experiencing any of these symptoms, book your car diagnostics in Swansea today. We’ll find the fault quickly and give you honest advice on the best way forward.

Our diagnostics cover a wide range of vehicle systems, including engine management, braking systems, electrical faults, emissions, and more. Whether it’s a minor issue or something more complex, we’ll pinpoint the problem and recommend the right solution.
