Diagnostics

When warning lights illuminate on your vehicle’s dashboard, it indicates that the onboard diagnostic system has detected a fault. This fault is logged and saved in the vehicle’s management system. At Hadley James Ltd, we specialize in advanced diagnostic fault-finding, using both main dealer diagnostic equipment and high-end aftermarket tools to accurately diagnose and repair faults in modern trucks, trailers, plant machinery, and vans.

Whether you’re experiencing starting issues, high fuel consumption, idle problems, excessive emissions, or general running concerns, we can quickly diagnose and repair the fault on-site.
