All makes, not one make

A1 Diagnostics is an independent garage, not a franchise. We are not a German car specialist and we are not tied to any single manufacturer — we service and repair whatever comes through the door, from a Fiat 500 to a Range Rover.

What makes that possible is equipment rather than luck. A modern car is a network of control units that are coded to that specific vehicle, and a generic code reader cannot see most of them. We hold manufacturer-level diagnostic systems for the makes we work on most, which is what lets us code modules, run guided tests and carry out the calibration routines a car needs after a repair — instead of guessing from a fault code and replacing parts one at a time.

What we do for every make

Servicing to the manufacturer schedule with the correct oil specification, MOT testing with the repairs done on site, engine work from oil services to rebuilds, clutches and gearboxes, brakes, air conditioning, diagnostics and auto electrics, and ADAS camera and radar recalibration in our own dedicated bays.

We upload the work to the manufacturer’s digital service record and stamp the book, so your history stays complete whichever make you drive. Servicing with an independent garage does not affect a manufacturer warranty, provided the work follows the manufacturer schedule and uses parts of matching quality.
