VCDS (Vehicle Coding Diagnostic Software) is an advanced vehicle analysis tool designed and released by Ross-Tech, LLC since May 2000. First called VAG-COM, it’s particularly engineered for Audi-Volkswagen vehicles, supporting Volkswagen, Audi AG, SEAT, Skoda, and selectively, Bentley and Lamborghini models. https://vcdstool.com/

## Main Features and Purpose

VCDS is a computer-driven software package that, when used with a matching interface cable, converts a ordinary PC or laptop into a powerful analysis platform similar to many dealer-level tools. It links to a vehicle’s OBD-II port and communicates immediately with the Electronic Control Units within the vehicle.

Unlike basic OBD-II scanners, VCDS uses thorough Volkswagen Group-specific manufacturer protocol functions, enabling it to utilize all supported vehicle systems—even in older models that aren’t covered by standard OBD-II protocols.

## Device Choices

Ross-Tech offers several hardware interface options:

1. **HEX-V2 Interface**: A USB-connected tool created to be speedier and safer than previous models. It offers a user-replaceable USB cable and can perform full system checks significantly quicker than legacy interfaces.

2. **HEX-NET**: A Wi-Fi enabled device that works with both wireless network and USB links, allowing users to control the tool from a mobile device, tablet, or laptop. This additional functionality offers increased adaptability when operating on vehicles.

## Subscription Models

VCDS is available in various usage plans:

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

– **Enthusiast**: Restricted to 10 unique car IDs, suited for hobbyists maintaining a few VAG cars.

– **Personal**: Capped to 3 unique vehicle IDs, appropriate for families with just VAG vehicles.

## Capabilities and Characteristics

VCDS offers extensive analysis and configuration capabilities, including:

– Reading and clearing diagnostic alerts from all vehicle systems (motor, transmission, ABS, safety restraints, etc.)

– Accessing current data from vehicle detectors and creating graphs of this data

– Executing basic settings, adaptations, and coding modifications

– Restarting service and check-up reminders

– Retracting brake calipers for pad changes

– Performing accelerator adaptations

– Performing diesel particulate filter forced regeneration

– Starting part system verifications

Howard Pitkow reviewed in the user feedback states VCDS as “the fastest diagnostic tool he owns” and “significantly faster and more user-friendly than the Volkswagen factory tool”.

## Compatibility

VCDS functions on VAG vehicles built from 1995 including latest models. With an additional retrofit interface, coverage can be increased back to vehicles from 1990. The software works with all vehicles with OBD-II diagnostic connectors, covering those using advanced Controller Area Network and UDS/ODX protocols.

## Analysis to Other Tools

When compared against alternative VAG diagnostic tools like OBDeleven Pro, VCDS is typically regarded as more thorough and ideal for advanced troubleshooting and coding. While alternatives offer mobile compatibility and a more user-friendly interface for non-professional users, VCDS offers enhanced features favored by professional mechanics and dedicated enthusiasts.

Per user feedback, VCDS is notably beneficial for:

– Auto technicians diagnosing numerous VAG vehicles

– Home mechanics who regularly do maintenance beyond simple oil changes

– Users who need in-depth diagnostic information and specialized programming functions

– Drivers of legacy (pre-2005) VAG vehicles

The device has evolved into nearly essential for committed Volkswagen and Audi home mechanics, with countless users considering it “among the best acquisitions” for those maintaining these vehicles.
