Accurate fault finding with dealer-level technology

When warning lights appear or something doesn’t feel right, guesswork isn’t good enough. At SJC Automotive, we offer professional vehicle diagnostics using advanced tools and systems that match main dealer capabilities, without the dealership price tag.

Our expertise goes beyond simple fault code reading. We carry out in-depth diagnostics across all vehicle systems, including coding and programming of replacement modules where required.

Whether it’s an intermittent electrical fault, dashboard warning, or a newly fitted part that needs configuring, we identify the issue and apply the correct solution.

We work with all makes and models, offering clear, honest advice and efficient fault resolution to save you time, money, and unnecessary hassle.
