If driver install fails, skip to Troubleshooting. Windows will install drivers automatically. When install is complete, do not launch VCDS. Uninstall any other VCDS versions, if present on computer. For that reason we recommend you get the high-quality VAG-COM 2021 cable with original, unlocked and full version of VCDS software from Ross-Tech™ - by clicking here.ĭO NOT plug VAG-COM cable into computer yet. If you own this kind of version, know half of it's functions don't work. Unfortunately 99% of them are using low-grade hardware chip with additional of cracked VCDS software ( sometimes needed an awkward computer date adjustment). There's several versions of VAG-COM sold online.
