When diagnosing vehicles from the Volkswagen Group (VW, Audi, Škoda, SEAT, etc.), two of the most popular software options are ODIS (Off-Board Diagnostic Information System) and VCDS (VAG-COM Diagnostic System). Each serves distinct purposes and caters to different users, so understanding their features and differences is crucial in selecting the right tool for your needs.
