Frequently asked questions
Some of the problems a diagnostic check can solve include:
• Engine warning light - if the engine warning light appears on your dashboard, it’s important to take your vehicle to a garage as soon as possible as there is a wide variety of problems which the light may be flagging up.
• Strange noises – any strange noises coming from your car need to be checked out before they turn into more serious problems. Some of these sounds may include; whining from the bonnet, abnormally loud exhaust, uneven engine noise, brake squealing or gear crunching.
• Smoke - if you see smoke or steam coming from under the bonnet, your vehicle may be overheating.
• Vibrating - if you notice any vibrating or pulling under your brake, the issue may be due to worn brake discs or pads. However, it could also indicate a problem with your suspension or steering.
When you book an appointment, you get:
• A full report of your vehicle's health
• State-of-the-art diagnostic tools
• Knowledge and advice from an expert mechanic
• Print-out results to show any issues or areas of concern
The test itself will let you know if you have any issues in the following areas:
• Engine Management
• Transmission
• Ignition Coils
• Throttle
• Exhaust
• Brakes
• Oil Tank
• And other major components
Identifying the problem early will give you the chance to get it fixed before it can become a more expensive repair.
