VAG-COM, now officially known as VCDS (an acronym for VAG-COM Diagnostic Software), is a third-party Windows-based software package developed and produced by Ross-Tech, LLC. It is primarily used for diagnostics and adjustments of Volkswagen Passenger Cars, Audi, SEAT, and Škoda automobiles, along with Volkswagen Commercial Vehicles. These are the five mainstream marques produced by the German automotive industry conglomerate and holding company Volkswagen Group (VWAG - which was formerly known as 'Volkswagen-Audi Group', or 'VAG'), where the software draws the first part of its name. VCDS will perform most of the functions of the expensive tools available only to official dealers, like the VAS 505x series diagnostic tools. In the past, these dealership-only tools have prevented owners and many small independent repair shops from performing some fundamental tasks, such as diagnosing problems, diesel ignition timing, modification of convenience options such as automatic door unlocking, coding a replacement electronic control unit (ECU) or key to the vehicle, and monitoring of many vehicle sensors for diagnosing problems. Unlike generic on-board diagnostics (OBD-II / EOBD), VCDS uses the more in-depth VWAG manufacturer-specific commands, which allows the user to access all diagnostic capable vehicle systems — even in vehicles which are not covered by generic OBD-II/EOBD (e.g., pre-1996). In general, there are two ways to use this software, either as a package (software and hardware) distributed by the manufacturer, or by building own interface hardware and using it with the public-available but limited shareware version of the software. VCDS is also capable of interfacing with many of the cars and light trucks sold in the United States after January 1, 1996, along with vehicles sold worldwide - which use the generic OBD-II/EOBD protocols. However, the OBD-II and EOBD standards only allow for limited diagnostics, and no adjustments to any of the ECUs.
