Since the introduction of the Emissions Regulations of 1993, all U.K. specification vehicles operate a fuel injection system that is controlled by an Electronic Control Unit (ECU). The ECU controls many sensors throughout your vehicle, including safety features like ABS braking systems, air bags, seatbelt restraints and in later vehicles items including the electric windows and stereo systems. From time to time these sensors, switches and control modules experience faults. Due to the complex nature of these systems, the use of computerised diagnostic equipment is required to locate the fault recorded within the ECU system. On some occasions you may see a lamp illuminated within the dashboards display. This is not the same for all vehicles as some use more complex systems. We are able to carry out diagnostic checks of most vehicles and retrieve information recorded as fault codes to assist in the repair of your vehicle.
