Vauxhall dealer-level diagnostics in Melton Mowbray
Stellantis dealer diagnostic platform in an independent workshop — programming, coding, keys and software for Corsa (2019 on) to Movano.
Vauxhall diagnostics with the dealer's own system
We run the Stellantis dealer diagnostic platform — the same system a franchised Vauxhall dealer plugs into your car. That means we see every control unit, not just the engine, and we can do the jobs that a generic tool cannot.
Dealer-level work on the current Stellantis-platform Vauxhalls. Older GM-era Vauxhalls (Insignia, Zafira, earlier Astra and Corsa) are covered by our standard diagnostics instead.
Models we see most
Corsa (2019 on), Astra (2021 on), Mokka, Crossland, Grandland, Combo, Vivaro, Movano — and the rest of the range.
What dealer-level lets us do on a Vauxhall
- Program and code replacement control modules
- Key and immobiliser work (SERMI — bring V5C and ID)
- Software updates and campaign fixes
- Guided fault-finding written by the manufacturer
- Driver-assistance, steering-angle and sensor calibration
- Service, adaptation and emissions-system resets
Questions people ask
Do you have the genuine Vauxhall dealer diagnostic tool?
Yes — Stellantis dealer diagnostic platform, the system a main dealer uses, at our workshop in Melton Mowbray.
Can you program a new key for my Vauxhall?
Yes. Key programming is security-related work under SERMI, so bring the V5C and photo ID — see our SERMI page for exactly what is needed.
Will using an independent garage affect my Vauxhall warranty?
No. Servicing and repairs to the manufacturer schedule with the right parts keep the warranty valid; we record everything on your sheet and in the digital service record where the maker supports it.
