  • Full fault code scanning and troubleshooting
  • Audi car diagnostics and ECU interrogation
  • Live data monitoring and sensor analysis
  • VW diagnostic checks in Swindon using factory-linked software
  • Coding and commissioning of new control units
  • Key and immobiliser programming

Dealer-level tools, independent garage prices

We’re the only independent centre in Swindon using Volkswagen’s own factory diagnostics (ODIS) with a direct manufacturer link. We also have full access to VW Group repair manuals, procedures and service plans – just like the main dealer.

With over 40 years’ combined experience and specialist tooling on site, we offer the highest level of diagnostic accuracy, helping to avoid unnecessary repairs and get you back on the road faster.


Why book your diagnostic check with VGS?

We use dealer-level diagnostics with ODIS and VCDS – the same fault-finding systems used by VW, Audi and Skoda main dealers. You’ll get clear, upfront pricing with no guesswork or unnecessary repairs. We keep you updated throughout the process and provide honest advice based on accurate diagnostics, not just fault code clearing.

FAQs

What’s the difference between your diagnostics and a basic scan tool?
Most garages use generic code readers that only show surface-level faults. We use Volkswagen Group’s official ODIS system, giving us deeper access to your vehicle’s data, modules and live sensor readings – just like the main dealer.
Can you diagnose issues with warning lights or intermittent faults?
Yes. Whether it’s a persistent dashboard light or an issue that comes and goes, our advanced diagnostics allow us to pinpoint the cause accurately, not just clear the fault code.
Do you offer Audi car diagnostics for S-line or RS models?
We work on all Audi models including performance variants. Our tools and experience mean we can run full diagnostics, module resets and coding updates for everything from an A1 to an RS6.
Can I book a diagnostic check alongside a service or MOT?
Yes, we can run a diagnostic alongside your scheduled service or MOT visit. It’s a good idea if you’ve noticed a warning light, reduced performance or any electrical issue.
