Opel and Vauxhall share the manufacturer's diagnostic application guidance. The appropriate system varies with the vehicle and its electronic architecture. The official Opel/Vauxhall diagnostic matrix lists the application, interface and configuration or programming method by model.
Tool families
Tech 2 and Tech2Win: used for specified earlier models; Tech2Win emulates the handheld tool on a PC. Service Programming System (SPS) is identified for configuration and setup in the matrix.GDS2 with MDI, MDI 2 or Opel/Vauxhall VCI: the matrix lists this combination for a range of models, with SPS for configuration and setup.Opel/Vauxhall Diagbox: the matrix identifies this application for newer vehicles from Vivaro / Zafira Life (K0), with MDI 2 or Opel/Vauxhall VCI. Confirm the current vehicle entry before use.
Why the exact vehicle matters
The official matrix lists Meriva B before model year 14.5 with Tech2Win and from model year 14.5 with GDS2. Models do not all change tools at the same time, and the matrix also has individual model exceptions. Identify the model, model year and applicable interface rather than treating a single date as a universal changeover. Opel/Vauxhall matrix.

Revision 1: Opel diagnostic systems
Opel and Vauxhall share the manufacturer's diagnostic application guidance. The appropriate system varies with the vehicle and its electronic architecture. The official Opel/Vauxhall diagnostic matrix lists the application, interface and configuration or programming method by model.

Selected model and year coverage
The September 2026 manufacturer matrix gives the following model-specific examples. Its broad Tech 2 rule applies to other vehicles before MY2015 unless the matrix names a later transition; model generation labels alone do not always specify an exact year range.
| Application | Documented model / year scope | Overlap or note |
|---|
| Tech 2 / Tech2Win | Other Opel/Vauxhall vehicles before MY2015; Meriva B before MY14.5; Movano / Movano-B before MY15 | Shared GM handheld platform; check Tech 2 or Tech2Win and the specified interface by model. |
| GDS2 with SPS | Antara from MY2011; Meriva B from MY14.5; Movano-B from MY2015. Matrix also lists Adam, Astra-K, Combo-D/E, Corsa-E, Crossland X, Grandland X, Insignia-B, Mokka and Vivaro-B without a specific year range. | Uses GM GDS2 family and supported MDI/MDI2 or Opel/Vauxhall VCI; configurations use SPS. |
| Opel/Vauxhall DiagBox | Vehicles in the diagnostic generation from Vivaro / Zafira Life (K0) onward, as stated in the current matrix. | PSA/Stellantis-origin application; see DiagBox coverage. The matrix uses K0 rather than a universal model-year cutoff. |
