Good, would use again
"Smooth transaction, will use them again for future work"
"Good service, kept in touch, did the work in a few hours, good value"
"I had my MOT due, however I also had two children with me a holiday club to get to and a baby with chicken pox... so I needed my car to be out of action for as short amount of time as possible. The wonderful lady who booked us in really worked her magic to make sure everything went like clockwork and the car was only gone for as minimum amount of time as they could. Car flew through, guys were lovely as always, been going to Johnson’s for years now. The new premises are looking great too. Thank you all. Can’t recommend them enough."

Today’s vehicles are manufactured with complex interrelated electronic systems. On-board computers continuously monitor and store information concerning the performance of these systems. If you see a warning light on the dashboard, this is because the computer has sensed a signal from one of the systems or components which has gone outside of its normal operating range. This is when your vehicle needs to be plugged in for a diagnostic check.
Your garage will have the specialist equipment need to communicate with your car's electronics. It will show them details of any faults reported by the car, and help them to understand exactly what the problem is that is causing a warning light to come on. They can then tell you how serious the problem is (or not!), and what they will need to do to fix the problem.
