Initially referred to as VAG-COM, it’s exclusively engineered for Audi-Volkswagen vehicles, including Volkswagen, Audi, SEAT, Skoda, and partially, Bentley and Lamborghini models. https://vcdstool.com/

## Main Features and Application

VCDS is a computer-driven digital tool that, when combined with a matching diagnostic lead, converts a regular PC or laptop into a high-performance analysis platform equivalent to many factory tools. It links to a vehicle’s system interface and works directly with the Electronic Control Units throughout the vehicle.

Unlike generic OBD-II scanners, VCDS uses in-depth Volkswagen Group-specific manufacturer protocol functions, enabling it to access each supported vehicle systems—even in older models that fall outside by generic OBD-II standards.

## Device Choices

Ross-Tech offers several diagnostic lead options:

1. **HEX-V2**: A physical cable device designed to be quicker and reliable than previous models. It features a swappable USB cable and can execute automatic diagnostics much more rapidly than legacy interfaces.

2. **Network Interface**: A Wi-Fi enabled interface that accommodates both internet and USB connections, permitting users to control the tool from a smartphone, iPad, or laptop. This expanded functionality delivers greater flexibility when working on vehicles.

## License Types

VCDS is available in multiple license types:

– **Professional (Unlimited)**: For professionals or users who work on multiple different vehicles.

– **DIY**: Limited to 10 unique VINs, suited for hobbyists servicing multiple VAG cars.
