The error “Interface not found” is a common issue encountered by VCDS users, especially with older versions like 11.11.3. This error indicates that the VCDS software cannot communicate with the diagnostic interface connected to your vehicle. This guide will walk you through common causes and solutions for this problem.
Common Causes of “Interface Not Found” Error
Several factors can contribute to the “Interface not found” error in VCDS 11.11.3:
- Incorrect COM Port Selection: VCDS needs to communicate through a specific COM port assigned to your interface. An incorrect selection in the software settings will prevent connection.
- Driver Issues: Outdated, corrupted, or missing drivers for your VCDS interface can hinder communication.
- USB Connection Problems: A faulty USB cable, port, or hub can disrupt the connection between the interface and your computer.
- Interface Compatibility: VCDS 11.11.3 is an older version and may not be compatible with newer vehicle models or operating systems.
- Faulty Interface: The diagnostic interface itself may be malfunctioning.
- Firewall Interference: Your computer’s firewall might be blocking VCDS from communicating with the interface.
- Antivirus Software Interference: Similar to firewalls, antivirus software can sometimes interfere with VCDS operation.
Troubleshooting Steps
Follow these steps to diagnose and resolve the “Interface not Found” error:
-
Verify Correct COM Port:
- In VCDS, go to Options and select the correct COM port assigned to your interface.
- Use the “Test” button to check communication. If unsuccessful, try different COM ports.

-
Update or Reinstall Drivers:
- Download the latest drivers for your specific VCDS interface from the Ross-Tech website.
- Uninstall existing drivers and install the new ones.

Test Interface on Another Computer:

-
Disable Firewall/Antivirus Temporarily:
- Temporarily disable your firewall and antivirus software to see if they are interfering with VCDS. If the interface works, create an exception for VCDS in your security software. Remember to re-enable your firewall and antivirus after testing.
