VCDS (commonly called VAG-COM) is diagnostic software made by Ross-Tech for Volkswagen Group vehicles (VW, Audi, SEAT, Škoda, etc.). Version 12.12 is a Windows application used with Ross-Tech interfaces (e.g., HEX-V2, HEX-NET) to read/clear fault codes, view live data, run guided tests, adapt modules, and perform coding.
| Vehicle Model Year | Works? | Limitations | |---|---|---| | 1996–2005 (K-line) | Yes | Full diagnostics, adaptations. | | 2006–2010 (partial CAN) | Mostly | Slower, occasional module drops. | | 2011–2014 (full CAN) | Sometimes | No UDS, some controllers unreachable. | | 2015+ (UDS) | No | Will fail to communicate. |
VCDS Lite is often the best compromise. You can download it legally from Ross-Tech for free. It supports most pre-2005 VAG cars and works with generic VAG-COM cables (not true for modern VCDS).
