Want to be proactive about your vehicle's health? A diagnostic check can help you solve problems before they worsen.
What Can a Diagnostic Check Tell Me About My Car?
Including an examination of your vehicle’s electronic and mechanical systems, a car diagnostic test identifies potential issues affecting vital components such as the following:
Engine
Brake system
Exhaust system
Ignition system
Suspension
Airbags
A professional diagnostic check helps a mechanic pinpoint what is causing problems with your car – some issues may require a manual inspection alongside diagnostics.
The test will generate error codes which can give the mechanic a better understanding of your vehicle’s issues – which in turn make it easier to determine the repairs your car may need.
If you’re not sure what’s wrong with your car, a diagnostic check can help to spot minor issues early on, before they lead to a more costly repair.

Frequently asked questions
Once you’ve chosen your garage, you deal with them directly from start to finish, paying only after the work is complete – giving you full peace of mind.
Some mobile technicians may request some commitment or payment upfront to cover the costs of them coming out to you.
However, if the light is only a steady amber, you should be able to safely drive your car home or to a local garage – but we don’t recommend driving it any more than is necessary as you may make the problem worse.
If you notice a flashing amber or red engine management light, you should not drive your car, pulling over as soon as it is safe to do so if it comes on while driving. This indicates a more serious issue that needs fixing as soon as possible. You may need to contact your recovery provider or a tow truck to get you to the garage.
You can select ‘Mobile Mechanics Only’ to filter static garages out of the results if you need a mobile technician to fix your car.
This is especially useful if you’ve noticed a flashing amber or red engine management light.
