Technical Improvements: Enhanced support for DoIP (Diagnostics over IP) communication and corrected basic setting/output tests for ASAM/UDS protocols.

Security: Continued support for unlocking SFD-protected (Vehicle Diagnosis Protection) modules, which is essential for newer VW Group cars. Software Access and Installation

Genuine VCDS software is available for free download directly from the official Ross-Tech website.

Licensing: While the software is free to download, full functionality requires a licensed Ross-Tech interface (hardware cable), such as the HEX-V2 or HEX-NET.

Hardware Compatibility: Modern versions of VCDS require current interfaces for 2019 and newer cars; legacy interfaces like the HEX+CAN will not work properly with these newer models. Counterfeit Risks and "2021" Confusion

The mention of "2021" in your query often appears in listings for counterfeit or "clone" cables found on third-party marketplaces. Do not search for “Ross Tech Vcds 23

Clone Cables: These often come with "cracked" versions of the software on mini-CDs. They typically cannot be updated, and attempting to use them with genuine, downloaded software from Ross-Tech can "brick" (permanently disable) the interface.

Official Timeline: In 2021, Ross-Tech actually released Release 21.3 and Release 21.9, adding support for 2022 models and preliminary SFD support.
