The "License Revoked" error in VCDS (VAG-COM Diagnostic System) typically signifies that the software no longer recognizes the communication cable as a legitimate, licensed interface
. This status often occurs when the software detects a non-genuine "clone" cable or when a genuine cable's internal data has been corrupted. Common Causes for Revocation Non-Genuine Cables
: Using "clone" or pirated cables with genuine VCDS software often triggers a revocation once the software connects to the internet and identifies the hardware as illegitimate. Firmware Corruption
: Failed or interrupted firmware updates can leave the interface in a "Questionable" or "Revoked" state. Third-Party Software Interference
: Some aggressive software packages can rewrite data on the cable's internal chipset, rendering the license invalid. Exhausted VIN Slots
: For limited-VIN interfaces (e.g., 3-VIN or 10-VIN versions), exceeding the allowed number of unique vehicles can lead to a restricted or revoked status for new vehicles. Fixes and Solutions Re-run Firmware Updates : For genuine
interfaces like HEX-V2 or HEX-NET, you can often clear errors by forcing a firmware refresh. Open VCDS and go to Check for Updates Download Update to reset the interface firmware. Verify Drivers
: Ensure the correct USB drivers are installed. You can manually update these via Windows Device Manager by pointing to the VCDS installation folder (usually C:\Ross-Tech\VCDS\ Clean Installation
: Uninstall VCDS completely, delete the Ross-Tech folder, and reinstall the latest version directly from the Ross-Tech official site Hardware Replacement (for Clones)
: If a clone cable is revoked, it is often permanently "bricked" by the genuine software. The most reliable fix is purchasing a new interface and ensuring it remains disconnected from the internet during use. Official Support/Registration
: Owners of second-hand genuine cables may need to pay a registration fee to to transfer ownership and receive full technical support. block VCDS from the internet to protect your interface in the future?
A "License Revoked" error in VCDS typically occurs if a clone (non-genuine) cable is used with a newer software version or if it attempts to connect to the internet, causing Ross-Tech's servers to flag and "kill" the interface's internal chip. 1. Identify the Cause
Clone Interfaces: Most "revoked" cases involve clone HEX-V2 or HEX-CAN cables. Newer VCDS software can detect these and overwrite the cable's firmware to disable it.
Failed Firmware Update: Genuine cables can also appear "revoked" or "stuck" (indicated by flashing red lights) if a firmware update was interrupted. 2. Fixing a Genuine Cable (Ross-Tech)
If you own a genuine interface, you can usually fix this by forcing a firmware refresh.
Open VCDS Config: Launch VCDS and click on Options, then Config. Access Update Tab: Navigate to the Update tab.
Force Update: Click Check for updates. If it finds an update, click Download update. This often resets the license state to "Valid" after a successful flash.
Test on Car: Plug the interface into a vehicle's OBD-II port (this provides 12V power) and run a Test in the Options menu to confirm status. 3. Fixing a Clone Cable (Blocked/Revoked)
If your clone cable is revoked, it is often "bricked" at the hardware level. Some community-sourced methods may work to reactivate it:
Uninstall VCDS: Remove the current version of VCDS entirely.
Disable Internet & Antivirus: Disconnect your laptop from the internet and disable Windows Defender/Antivirus, as they often delete the "loader" files required for clones.
Use a Loader: Clones typically require a specific VCDSLoader.exe file.
Reinstall the VCDS version that originally came with your cable.
Copy the loader file into the Ross-Tech installation folder.
Always launch the software using the loader shortcut, never the original VCDS.exe.
Registry/Date Hack (Last Resort): Some users attempt to set their PC date back 1–2 years to bypass license checks, though this is rarely successful for revoked statuses. 4. Preventing Future Revocations
Block in Firewall: Use Windows Firewall to block VCDS.exe from accessing the internet.
Turn off Auto-Updates: In VCDS Options, set the "Check for Updates" frequency to "Never". Offline Use: Only use the diagnostic laptop while offline.
For genuine Ross-Tech cables showing errors, follow this guide to force a firmware update and restore functionality:
The "Revoked" license status in VCDS typically occurs when the software detects an unauthorized or "clone" interface, or if a genuine device's internal security certificates have expired or been flagged. For Genuine Ross-Tech Interfaces
If you are using a genuine interface, a revoked status is usually a technical glitch or a result of a failed firmware update.
Force a Firmware Update: Access the VCI Config utility by going to "Options" then clicking the "Config" button. Go to the "Update" tab and click "Check for Updates" then "Download Update". This can often reset the interface and restore the license.
Contact Official Support: If the device remains revoked, genuine users can contact Ross-Tech Support with a screenshot of their "About" screen to have the license manually reinstated. For Non-Genuine (Clone) Interfaces
"Revoked" is a common defense mechanism in official Ross-Tech software when it detects pirated hardware. Once revoked, the cable is often "bricked" and cannot be easily used with newer software versions.
Offline Isolation: To prevent this, clone users often use an older laptop that is permanently disconnected from the internet or set a firewall rule to block the VCDS executable from connecting to the web.
Loader Usage: Some third-party "loaders" claim to bypass the license check, but these are often unstable and may contain security risks.
Firmware Reflash: Expert users sometimes attempt to reflash the interface's EEPROM with a known good serial number (like RT000001), though this is difficult and often unsuccessful once the software has flagged the hardware.
If your genuine interface has lost its connection, you can often restore it by forcing a firmware update through the VCI configuration utility:
In the world of car diagnostics, a "VCDS revoked" status usually feels like a dead end, but it’s often a fixable software conflict or a side effect of using "clone" hardware. The "Revoked" Backstory
The VCDS (Vag-Com Diagnostic System) license is tied directly to the interface cable
, not just the software. When you see a "License Status: Revoked" message, it typically means the software has detected something it doesn't like: The "Clone" Trap:
Many users buy cheaper, non-genuine cables. If these cables connect to the internet while the VCDS software is running, Ross-Tech’s "anti-piracy" measures may "brick" or revoke the cable’s internal firmware. Software Mismatch:
Using a newer version of VCDS with an older or clone cable can trigger a revocation because the new software recognizes the hardware as unauthorized. Hardware Failure:
Occasionally, a genuine cable’s EEPROM (memory) can become corrupted or misidentified due to age or electrical interference, leading to an accidental "revoked" status. Common Fixes & "Survival" Strategies vcds revoked fix
Depending on your hardware, here is how the community typically handles a revoked status: Reflashing the EEPROM:
For advanced users with certain "Hex-V2" clones, they often use third-party "loaders" (like Loader 9.2) or firmware updaters found on forums like Reddit's CarHacking community
to reset the cable’s internal data and clear the "revoked" flag. The "Air-Gap" Method:
To prevent revocation in the first place, many tech-savvy owners run VCDS on a dedicated laptop or a Virtual Machine (VM)
with all network interfaces disabled. This stops the software from "calling home" and flagging the cable. Firmware Force-Update:
If you have a genuine Ross-Tech HEX-V2 or HEX-NET that is acting up, you can sometimes fix it by using the VCI Config utility
. This involves clicking the "Net" then "Config" buttons to force a fresh firmware download, which can reset a "questionable" license state. The "Date Back" Trick: Some users on TDIClub Forums
have tried setting their PC's system date back to a time when the license was valid, though this is often an unstable, temporary fix and can cause "implausible date" errors in the software.

Interface status shows "Revoked," "Not Found," or "Unregistered" even if physically connected. Risk Factor
Connecting to the internet while VCDS is open or updating to a newer version than the one provided with the cable. Technical Fix Procedures 1. The "Clean Reinstall" (Software Level)
For some users, the revocation is stored in the local registry or program files.
Disconnect Internet: Disable Wi-Fi and unplug Ethernet to prevent the software from checking the license server. Uninstall VCDS: Completely remove the current version.
Clean Registry: Delete any remaining "Ross-Tech" folders in C:\ and use a registry cleaner to remove traces of the old installation.
Install Specific Version: Reinstall only the exact software version that originally came with your cable. Do not download the latest version from the official Ross-Tech site if you are using a clone.
Firewall Block: Before opening, create an Outbound Rule in Windows Firewall to block VCDS.exe from accessing the internet. 2. The "Loader" Method (Clone Cables)
Many third-party cables require a specific "Loader" application to bypass license checks.
Copy Loader: Move the vcds_loader.exe provided by the vendor into the C:\Ross-Tech\VCDS directory.
Launch via Loader: Always open the program using the Loader shortcut, never the original VCDS.exe icon. 3. Hardware Flashing (Advanced Fix)
If the firmware inside the cable is truly "bricked," software fixes may not work.
Reflashing the EEPROM: This requires opening the cable and using tools like a USBASP programmer or MProg to rewrite the chip's data (often an ATMEGA162 or FT232RQ).
Hardware Modification: Some users on community forums like Reddit's CarHacking or TDIClub suggest adding pull-up resistors or capacitors to the circuit if the hardware was damaged during the "revoke" signal. Prevention Checklist Never Update: Ignore all prompts to update the software.
Offline Only: Only use the laptop for VCDS when Wi-Fi is toggled off.
Genuine Upgrade: If you require constant updates and technical support, the only permanent fix is purchasing a genuine interface directly from Ross-Tech. AI responses may include mistakes. Learn more Fixing blocked cable error on cracked VCDs?
The "License Revoked" error in VCDS typically occurs when non-genuine or "clone" cables are used with original Ross-Tech software that has been updated or connected to the internet. Why the License is Revoked
Genuine Software with Clone Hardware: Official VCDS software is designed to detect and disable (or "brick") unofficial hardware clones.
Firmware Mismatch: Connecting a clone cable to the internet allows the software to update its blacklist, revoking the license tied to the cable.
Second-Hand Genuine Cables: In some cases, genuine cables may show "revoked" if they were not properly registered by a second-hand owner or if all VIN slots on a limited-VIN cable have been used. Potential Fixes Reading and clearing fault codes Viewing vehicle data
Fresh Reinstallation: Some users have found success by deleting all VCDS drivers and files from their laptop and performing a fresh install, sometimes specifically choosing the 32-bit version even on 64-bit systems.
Firewall Blocking: To prevent future revocations, create a Windows Firewall rule that prevents VCDS from connecting to the internet.
Forced Firmware Update (Genuine Cables): If a genuine cable is stuck in a "questionable" state due to a failed update, you can force a re-flash through the VCI Config Utility by clicking "Check for Updates" and "Download Update" while the cable is connected.
Use a Loader: Unofficial cables often require a specific VCDS Loader program instead of the standard executable. Ensure the vcdsloader.exe is placed in the Ross-Tech folder and used to launch the program while the internet and antivirus are disabled.
Official Registration: If you have a genuine interface, you may need to pay a registration fee to Ross-Tech to transfer technical support rights and reactivate the full license for a new owner.
