VCDS (an abbreviation for "VAG-COM Diagnostic System" and formerly known as VAG-COM) is a Microsoft Windows-based software package, developed and produced by Ross-Tech, LLC since May 2000. It is primarily used for diagnostics and adjustments of Volkswagen Group motor vehicles, including Volkswagen Passenger Cars, Audi, Bentley (limited), Lamborghini (limited), SEAT, and Škoda automobiles, along with Volkswagen Commercial Vehicles. The name "VAG-COM" derives from the acronym for Volkswagen Auto Group (VAG), the former name of the Volkswagen Group.
VCDS will perform most of the functions of the expensive electronic diagnostic tools available only to official dealers, like the current 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 or EOBD), VCDS uses the more in-depth Volkswagen Group-specific manufacturer protocol 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 their 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 interfacing vehicles 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.
An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a vehicle.
A direct-shift gearbox, commonly abbreviated to DSG, is an electronically-controlled, dual-clutch, multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout, with automated clutch operation, and with fully-automatic or semi-manual gear selection. The first dual-clutch transmissions were derived from Porsche in-house development for the Porsche 962 in the 1980s.
On-board diagnostics (OBD) is an automotive term referring to a vehicle's self-diagnostic and reporting capability. OBD systems give the vehicle owner or repair technician access to the status of the various vehicle sub-systems. The amount of diagnostic information available via OBD has varied widely since its introduction in the early 1980s versions of on-board vehicle computers. Early versions of OBD would simply illuminate a malfunction indicator light or "idiot light" if a problem was detected but would not provide any information as to the nature of the problem. Modern OBD implementations use a standardized digital communications port to provide real-time data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow a person to rapidly identify and remedy malfunctions within the vehicle.
AUTomotive Open System ARchitecture (AUTOSAR) is a global development partnership of automotive interested parties founded in 2003. It pursues the objective to create and establish an open and standardized software architecture for automotive electronic control units (ECUs). Goals include the scalability to different vehicle and platform variants, transferability of software, the consideration of availability and safety requirements, a collaboration between various partners, sustainable use of natural resources, and maintainability during the whole product lifecycle.
OBD-II PIDs are codes used to request data from a vehicle, used as a diagnostic tool.
ETKA is the official electronic parts catalogue (EPC) for Volkswagen Group motor vehicles. Launched in 1989, ETKA superseded the older parts books and microfilm-based catalogues. ETKA is an abbreviation from the German: Elektronischer Teilekatalog. It is produced for Volkswagen AG by the Munich-based specialist automotive industry information systems software publisher LexCom Informationssysteme GmbH. As of July 2019 the latest release of the ETKA software is ETKA 8.2.
The Digifant engine management system is an electronic engine control unit (ECU), which monitors and controls the fuel injection and ignition systems in petrol engines, designed by Volkswagen Group, in cooperation with Robert Bosch GmbH.
Assembly Line Diagnostic Link or ALDL is a proprietary on-board diagnostics system developed by General Motors before the standardization of OBD-2. It was previously called Assembly Line Communications Link or ALCL. The two terms are used interchangeably.
APR LLC is an American automotive engineering and motorsport company that offers aftermarket performance products for cars built by the Volkswagen Group, including Audi, Porsche, SEAT, Škoda and Volkswagen. Audi Performance & Racing was founded in 1997 by Brett Augsburger and Stephen Hooks, automotive engineers looking to offer aftermarket upgrades for Volkswagen Auto Group cars. Their first product was an ECU software upgrade for the 1997 Audi A4 1.8T, but the company soon expanded its product line to include exhaust and turbo systems. APR engine tuning products use proprietary software for reading and writing to Bosch Motronic engine control units.
Association for Standardization of Automation and Measuring Systems or ASAM is an incorporated association under German law. Its members are primarily international car manufacturers, suppliers and engineering service providers from the automotive industry. The association coordinates the development of technical standards, which are developed by working groups composed of experts from its member companies. ASAM pursues the vision that the tools of a development process chain can be freely interconnected and allow a seamless exchange of data. The standards define protocols, data models, file formats and application programming interfaces (APIs) for the use in the development and testing of automotive electronic control units. A large amount of popular tools in the areas of simulation, measurement, calibration and test automation are compliant to ASAM standards. Compliance shall guarantee interoperability of tools from different vendors, allow data exchange without the need for converters, and facilitate the exchange of unambiguous specification between customers and suppliers.

Unified Diagnostic Services (UDS) is a diagnostic communication protocol used in electronic control units (ECUs) within automotive electronics, which is specified in the ISO 14229-1. It is derived from ISO 14230-3 (KWP2000) and the now obsolete ISO 15765-3. 'Unified' in this context means that it is an international and not a company-specific standard. By now this communication protocol is used in all new ECUs made by Tier 1 suppliers of Original Equipment Manufacturer (OEM), and is incorporated into other standards, such as AUTOSAR. The ECUs in modern vehicles control nearly all functions, including electronic fuel injection (EFI), engine control, the transmission, anti-lock braking system, door locks, braking, window operation, and more.
