When a problem occurs, the fault is logged on the ECU’s memory. A diagnostic code reader has to be used to read the fault or message and to clear any fault codes from the memory.

This is why having the correct diagnostics equipment is vital. It means we can fix cars quicker and therefore, pass the time saving onto our customers


All modern vehicles are equipped with an on-board computer diagnostic system (OBDII) that constantly monitors your vehicle’s engine and transmission together with the entire electrical systems. The main purpose of monitoring these systems is to ensure that the vehicle is operating at top efficiency with the lowest possible emissions.

A warning light comes on because the computer has sensed a signal from one of the systems or components that has gone outside of its normal operating range. The computer then sends a signal to turn on the light on your dashboard to let you know something is wrong!

It’s possible that a warning light may turn on, and your car may still appear to be driving OK. Ignoring some warning lights can lead to serious issues and expensive repairs. In the event of a warning light coming on in your vehicle, you should safely pull up to the side of the road and call us for assistance.
