Frequently
asked questions
1. What is a diagnostic scan?
A computerised scan connects to your car’s ECU (Engine Control Unit) to detect faults in the engine, transmission, brakes, airbags, and electrical systems.
2. Can I drive with the check engine light on?
If the check engine light is flashing – stop driving immediately!
 A solid light means a minor issue, but it’s best to get a scan ASAP to prevent further damage.
3. How long does a diagnostic scan take?
A basic scan takes 30-60 minutes, but troubleshooting complex faults may take longer.
4. Will a diagnostic scan fix my car’s issue?
No, but it helps us identify the problem quickly, so we can recommend the right repairs.
5. Do I need a diagnostic scan if no warning lights are on?
If you notice power loss, poor fuel economy, or strange noises, a scan can detect hidden faults before they become major issues.
