VCDS is a powerful Windows-based diagnostic software suite designed by Ross-Tech for VAG vehicles. It allows users to read and clear diagnostic trouble codes (DTCs), access and graph live data streams, perform output tests, and—most importantly for enthusiasts—perform complex coding and adaptations to activate hidden features or modify vehicle behavior.
