Frequently asked questions

There are many different signs which will indicate that your vehicle needs a diagnostic check. If you suspect that there is an issue with your car but don’t know what, you will probably want to book a diagnostic check to find out what the problem is.

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.
The price of a car diagnostic test can vary, depending on the garage that you visit. Each garage offers its car diagnostics for a fixed price, ranging from £30 - £100.

A diagnostic check can detect problems with your vehicle which may be difficult to spot manually. It includes a full health check of your car's engine and electrical systems. A technician will plug your vehicle into a specialised code reader and scan the ECU (Engine Control Unit) for fault codes. They will then interpret these fault codes and find the exact cause of your issue.

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
Car diagnostics take around 90 minutes to complete. Depending on the cause of your problem, the repair time may take longer. A technician will contact you once they have an accurate idea of the problem to provide a repair quote.
A diagnostic check can detect a potential problem with your car, even before a breakdown. It is also a quick, easy and accurate way to understand any issue with your car. This can include a dashboard warning light or strange noise.

Identifying the problem early will give you the chance to get it fixed before it can become a more expensive repair.
