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.
