An engine diagnostic tool is a computer car code reader that plugs into the car’s computer system and displays a fault code. The fault code will tell the mechanic where the issue is coming from having scanned all the cars sensors.
Professional mechanics use a specialist diagnostic software tool to get to the bottom of faults which are harder to diagnose at home or with basic code readers. If you notice any warning lights on the dashboard e.g. Engine Management Light, it could be indicative of a serious component failure and the car should not be driven until it is checked by a professional.
The diagnostic tool we use will diagnose most faults, but if the fault is out of our scope, such as a deeper electrical issue, we have an extensive network of partners who can help so you are always in safe hands.
