Our state of the art computerised diagnostic service will ensure that your car is fault free and runs smoothly. It instantly highlights and isolates issues with the Vehicle Engine Management system, fuel system and ignition system.

Problems with the vehicle engine management, fuel & ignition systems may cause:

• Engine misfires
• Intermittent or occasional stalling of the engine

Emissions Testing

The emissions test is an important part of the MOT, and if your vehicle fails we have the equipment and expertise to ensure the problem is rectified promptly.
