Reviews Summary

AI Generated

Customers consistently praise the garage for its professional, friendly mechanics who arrive punctually, communicate clearly throughout the service, and provide helpful advice, with many highlighting the convenience of the mobile service and competitive pricing. The mechanics are frequently described as knowledgeable and thorough, taking time to explain work completed and any issues identified. One reviewer experienced poor communication when their appointment was rescheduled without adequate follow-up, and another mentioned the service indicator was left on (though this was easily resolved), but these concerns were raised only occasionally.

Want to maintain peak performance and to benefit from early problem detection?

Booking a diagnostic check for your car can give you the peace of mind you deserve and help you find a solution in no time.

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

We never ask for payment details upfront.

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.
Absolutely. True value looks different to everyone so, whether you want the nearest garage, the best-rated option or the lowest price, you can use the Sort By menu in the top-right corner to compare results by Price, Distance, Availability or Reviews - whatever matters most to you.
You can change your booking details right up until the appointment date. You’ll find instructions in the confirmation email you received or in your MyGarage account. Your chosen garage will contact you to acknowledge the amendment and re-confirm your booking.
We recommend booking a diagnostic check as soon as your engine management light comes on.

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.
Yes, we work with a growing network of mobile mechanics who provide at-home car repairs on stricken vehicles.

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.
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.
