A revoked VCDS license can be frustrating. This article explores common causes and solutions for this issue, focusing on Ross-Tech’s official stance and potential hardware or software conflicts.
Understanding VCDS Licensing
Ross-Tech only provides direct support to the original purchaser of a VCDS kit. Reselling VCDS interfaces is permitted, and subsequent owners can download the latest VCDS software: https://www.ross-tech.com/vcds/download/current.php. However, support is not guaranteed unless a separate software license is purchased: https://store.ross-tech.com/shop/VUDOT.
Common Causes of a Revoked VCDS License
A “Vcds License Revoked” message usually indicates a problem with the interface hardware, not necessarily a license issue. Two primary causes include:
Hardware Failure
Random hardware failures, particularly with older interfaces like the KEY-USB (discontinued in 2008: https://www.ross-tech.com/vag-com/old-interfaces/discontinued_interfaces.php), can prevent the software from recognizing the device. This can mistakenly appear as a revoked license.
Software Conflicts
Conflicting software, often from third-party or counterfeit diagnostic tools, can overwrite data on the FTDI chipset within genuine Ross-Tech devices. This corruption can render the interface invalid, triggering the “revoked license” error.
Troubleshooting Steps
If you encounter a “VCDS license revoked” message:
- Verify Hardware: Ensure your interface is a genuine Ross-Tech product. Check for physical damage.
- Check Software Compatibility: Confirm you are using the latest VCDS software version compatible with your operating system.
- Consider Hardware Age: Older interfaces are more susceptible to failure. The KEY-USB, for example, is over 15 years old.
- Contact Ross-Tech: If you are the original purchaser, contact Ross-Tech support for assistance.
Conclusion
While a “VCDS license revoked” message can be concerning, it often stems from hardware issues or software conflicts rather than actual license revocation. Understanding the potential causes and troubleshooting steps can help resolve the problem. Remember, Ross-Tech supports original purchasers and allows for reselling interfaces, ensuring continued access to the VCDS software for legitimate users.
