Modern vehicles are more like computers these days, which also need attention from time to time to stop little problems becoming big ones!

Diagnostics: Frequently Asked Questions


How long does your Diagnostic Testing take

Most tests and conclusions are resolved within 30mins but sometimes we will need the vehicle for bit longer.

How much do you charge for repairs after the Diagnostic Test

The cost can vary as systems and components differ greatly from manufacturer to manufacturer. But more often than not, it will be a very simple solution such as cleaning a contact, overriding an error code or restoring the system.

My vehicle is pretty high-tech, can you still do it

Yes, our Mechanics have Main Dealer experience and we regularly test the diagnostics on executive cars, supercars, sports cars and other unknown / unusual makes.
