# VAG-COM Diagnostic System: Detailed Explanation

VCDS (Vehicle Coding Diagnostic Software) is an sophisticated car scanning tool created and released by Ross-Tech, LLC starting from May 2000. Originally known as VAG-COM, it’s exclusively engineered for Audi-Volkswagen vehicles, including VW, Audi AG, SEAT, Skoda, and selectively, Bentley and Lamborghini models. https://vcdstool.com/

## Primary Capabilities and Use

VCDS is a Windows-based program suite that, when used with a supported interface cable, turns a regular PC or laptop into a powerful analysis platform equivalent to many factory tools. It connects to a vehicle’s OBD-II port and works immediately with the ECUs within the vehicle.

Unlike basic OBD-II scanners, VCDS uses in-depth Volkswagen Group-specific proprietary language commands, permitting it to reach all diagnostic-capable vehicle systems—even in pre-1996 models that aren’t covered by standard OBD-II standards.

## Device Choices

Ross-Tech offers several connection device options:

1. **HEX-V2**: A wired tool engineered to be speedier and reliable than older models. It includes a replaceable USB cable and can execute auto-scans significantly quicker than previous devices.

2. **Network Interface**: A cordless interface that supports both internet and USB links, permitting users to use the tool from a tablet, Android device, or laptop. This enhanced functionality delivers greater versatility when working on vehicles.

## License Types

VCDS is available in several usage plans:

– **Professional (Unlimited)**: For technicians or users who service many different vehicles.

– **Enthusiast**: Capped to 10 unique vehicle identification numbers, perfect for DIYers working on several VAG cars.

– **Residential**: Capped to 3 unique VINs, appropriate for families with just VAG vehicles.

## Capabilities and Features

VCDS offers extensive scanning and configuration options, such as:

– Retrieving and erasing fault codes from every vehicle systems (motor, transmission, ABS, safety restraints, etc.)

– Accessing real-time data from vehicle detectors and producing visualizations of this data

– Executing standard configurations, customizations, and coding modifications

– Restarting service and check-up reminders

– Resetting brake calipers for maintenance

– Performing accelerator adaptations

– Initiating diesel particulate filter forced regeneration

– Starting module actuation tests

A professional mechanic evaluated in the search results describes VCDS as “the quickest diagnostic tool he owns” and “significantly speedier and simpler than the Volkswagen factory tool”.

## Vehicle Support

VCDS supports VAG vehicles manufactured from 1995 up to modern models. With an optional legacy connector, coverage can be extended back to vehicles from 1990. The software works with all vehicles with standard ports, covering those using advanced CAN and UDS/ODX protocols.

## Analysis to Alternative Systems

When evaluated against other VAG diagnostic tools like OBDeleven Pro, VCDS is usually considered as more comprehensive and ideal for complex troubleshooting and coding. While OBDeleven provide mobile compatibility and a simpler interface for casual users, VCDS provides superior functions favored by professional mechanics and experienced enthusiasts.

According to user testimonials, VCDS is notably useful for:

– Auto technicians diagnosing numerous VAG vehicles

– DIY enthusiasts who frequently conduct maintenance exceeding simple oil changes

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

– Users of legacy (pre-2005) VAG vehicles

The device has grown into nearly essential for serious Volkswagen and Audi home mechanics, with many users regarding it “among the best investments” for those servicing these vehicles.
