Vehicle Diagnostic Check

A warning light on your dashboard can be a worry. With a diagnostics check the issue can be quickly identified and stop a huge expense later down the line.

As technology becomes more advanced unfortunately that means that there are potentially more issues that could occur with your vehicle. A diagnostics check can reveal issues with the engine, brakes, exhauxt system and many more larger components and also performance issues e.g. air flow throttle etc. it can even check various sensors throughout the vehicle.

What is a diagnostics check?

Most modern vehicles today contain an on-board computer known as an Engine Control Unit (ECU) which continually monitors the performance of the vehicle. Sensors all around the vehicle report back to the ECU if there are problems such as low fluid levels or increased engine temperature. When an issue is identified the ECU generates an error code. The relevant dashboard warning lights will then be displayed.

There are hundreds of potential error codes that can only be read by specialist vehicle diagnostic equipment. While a warning light may display on the dashboard alerting you to an issue, a diagnostics check is required to understand the full extent and cause of the problem.

When should you get a Diagnostics Check
