        When car warning lights illuminate on your dashboard, an engine diagnostics check can help identify the problem before more serious damage occurs.

        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 literally 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.

        At WESSEX we use state of the art equipment for vehicle diagnostics which can read the engine fault codes in your ECU’s memory. Our fully-trained technicians can then suggest any necessary repairs to get you back on the road and rectify the error. Next time a dashboard warning light appears in your car, don’t pay vehicle dealership prices for your diagnostics check, call into Wessex for a low-cost diagnosis while you wait.  Or alternatively, book your appointment today.

        What does the car diagnostic equipment check for?

        Say for example your Check Engine light came on. Your engine is made up of hundreds of parts so the exact fault may not be obvious. Our diagnostic equipment reads the error codes generated by your vehicle’s Engine Control Unit to provide a full explanation of the issue. The car diagnostic test checks for faults across a wide range of vehicle systems including engine management, tyres, emissions, lights and comfort controls. Live data displays multiple values from around the engine to ensure all components are working as expected when rectifying an issue.

        The diagnostic equipment can also be used to reset service lights, test and adjust braking systems where an electronic handbrake is present, and adjust headlamp levels. For more information or to book your vehicle in for an engine diagnostics check, contact your local WESSEX Garage.
