## Core Functionality and Purpose

VCDS is a Windows-based software package that, when paired with a matching diagnostic lead, transforms a standard PC or laptop into a high-performance analysis platform comparable to many professional-grade tools. It connects to a vehicle’s diagnostic connector and works straight with the ECUs throughout the vehicle.

Unlike generic OBD-II scanners, VCDS uses thorough Volkswagen Group-specific proprietary language commands, allowing it to utilize every compatible vehicle systems—even in older models that don’t comply by generic OBD-II protocols.

## Device Choices

Ross-Tech offers several connection device options:

1. **HEX-V2 Interface**: A physical cable device designed to be quicker and more secure than previous models. It features a swappable USB cable and can conduct full system checks up to three times faster than older tools.

2. **HEX-NET**: A cordless tool that supports both internet and USB links, allowing users to control the tool from a mobile device, iPad, or PC. This expanded functionality provides greater flexibility when working on vehicles.

## Activation Versions

VCDS is available in several usage plans:

– **Full Access**: For professionals or users who work on numerous different vehicles.

– **DIY**: Capped to 10 unique car IDs, suited for enthusiasts working on multiple VAG cars.
