Modern vehicles rely on advanced electronic systems to monitor performance, safety and engine efficiency. When a warning light appears on your dashboard, it can be confusing and sometimes alarming, especially if the cause is not immediately clear.
Some dashboard lights are simply informative, such as low fuel or an unfastened seat belt, but others may indicate a fault that requires professional attention. In many cases, the warning light itself does not tell you exactly what has gone wrong — only that the vehicle has detected an issue within one of its systems.
At ST Garage, we provide professional vehicle diagnostics using up-to-date diagnostic equipment suitable for the vast majority of cars. By connecting your vehicle to the correct diagnostic system, we can read stored fault codes, assess reported issues and begin identifying the underlying cause of the problem.
Modern cars are fitted with onboard control units and sensors that constantly monitor key systems throughout the vehicle. If a fault is detected, the system stores an error code and may trigger a dashboard warning light.
A diagnostics test allows our technicians to access these fault codes and interpret the information recorded by the vehicle. This helps us identify faults linked to areas such as:
A dashboard warning light does not always point directly to the exact failed part. It often highlights the system where a fault has been detected, which is why proper diagnosis is essential before repairs are carried out.
At ST Garage, our trained technicians combine diagnostic equipment with hands-on fault finding to assess the issue properly and recommend the right next steps. This helps avoid unnecessary parts replacement and supports a more accurate and cost-effective repair process.

We use modern diagnostic equipment to scan your vehicle for stored fault codes and system errors. Once the vehicle has been checked, we can explain the results clearly and advise whether further testing, repair work or replacement parts may be required.
Our goal is to provide straightforward, honest fault finding and a professional service that helps you understand the issue before any repair work is carried out.
If we are unable to diagnose the fault with your vehicle, you will not be charged for the service.
