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.
