Vauxhall's factory diagnostic systems are covered in Opel diagnostic systems. The overview links to the shared Tech 2 and GDS2 articles and explains the model-dependent move to Opel/Vauxhall Diagbox.
Always check the precise model and year against the official Opel/Vauxhall diagnostic application matrix.
Coverage examples
Vauxhall follows the Opel application matrix. These examples are taken from the manufacturer’s September 2026 list; use the full matrix for other models and procedures.
| Vauxhall model / generation | Documented diagnostic application | Year information in matrix |
|---|---|---|
| Meriva B | Tech2Win before MY14.5; GDS2 from MY14.5 | Explicit model-year transition |
| Movano / Movano-B | Tech2/Tech2Win for earlier listed applications; GDS2 on Movano-B from MY2015 | Explicit MY2015 threshold for Movano-B |
| Vivaro-B | GDS2 | Generation listed; no year range supplied in matrix |
| Vivaro / Zafira Life K0 and newer supported architectures | Opel/Vauxhall DiagBox | Matrix identifies the generation, not a single universal year cutoff |
