Vagcom Software Version 21.3 (Spanish) and 25.3 (English)

VCDS (una abreviatura de “Sistema de Diagnóstico VAG-COM” y anteriormente conocido como VAG-COM) es un paquete de software basado en Microsoft Windows, desarrollado y producido por Ross-Tech, LLC desde mayo de 2000. Se utiliza principalmente para diagnósticos y ajustes de vehículos de motor del Grupo Volkswagen, incluidos los automóviles Volkswagen Passenger Cars, Audi, Bentley (limitado), Lamborghini (limitado), SEAT y automóviles Škoda, junto con los vehículos comerciales Volkswagen.

VCDS will perform most of the functions

of the expensive electronic diagnostic tools available only to authorized dealers, such as the current VAS 505x series diagnostic tools. In the past, these dealer-only tools have prevented owners and many small independent repair shops from performing some essential tasks, such as troubleshooting, setting diesel ignition timing, modifying convenience features like automatic door unlocking, programming a replacement electronic control unit (ECU) or vehicle key, and monitoring various vehicle sensors to diagnose problems.

Unlike generic on-board diagnostics (OBD-II or EOBD), VCDS uses the more detailed manufacturer-specific protocol commands for the Volkswagen Group— —which allow the user to access all diagnostic-capable vehicle systems, even in vehicles not covered by generic OBD-II/EOBD (e.g., pre-1996 models). In general, there are two ways to use this software: either as a package (software and hardware ) distributed by the manufacturer or its agents, or by building your own interface hardware and using it with the publicly available but limited shareware version of the software.

VCDS is also capable of communicating with vehicles that use the generic OBD-II/EOBD protocols. However, the OBD-II and EOBD standards only allow for limited diagnostics and do not permit adjustments to any of the ECUs.
