Common Causes of “VCDS Not Found Interface” Error

Troubleshooting Steps for “VCDS Not Found Interface”
Follow these steps to systematically diagnose and resolve the “VCDS Not Found Interface” error.
-
Check USB Connections: Begin by verifying all USB connections are secure. Try different USB ports on your computer, avoiding USB hubs if possible. If you’re using an extension cable, try connecting the interface directly to the computer.

-
Restart Your Computer: A simple reboot can often resolve temporary software glitches that might be interfering with communication.
-
Check Device Manager: Open Device Manager on your computer and look for the VCDS interface. It should appear under “Ports (COM & LPT)”. If it’s not listed, or if there’s a yellow exclamation mark next to it, there’s likely a driver issue.
-
Reinstall or Update Drivers: Download the latest drivers for your VCDS interface from the official Ross-Tech website. Uninstall the existing drivers and then install the new ones.
-
Disable Firewall/Antivirus Temporarily: Disable your firewall and antivirus software temporarily to see if they are blocking VCDS. If this resolves the issue, add an exception for VCDS in your security software settings.
-
Check COM Port Assignment: In VCDS, go to Options and check the selected COM port. Ensure it matches the COM port assigned to the VCDS interface in Device Manager.
