Verify the cable is receiving sufficient power. Test it while plugged into the car's OBD-II port with the ignition ON (engine off). Check for hardware issues. Older clones with chips may require different loader versions than newer interfaces.

If VCDS asks to update the software or firmware, say NO.

Expand , locate any remaining instances of the cable, right-click, and select Uninstall Device (ensure you check the box to Delete the driver software for this device ).

If your interface is stuck showing a failure status, follow these steps to restore its functionality. Step 1: Complete System Clean

Official VCDS software requires internet access to update the firmware on modern interfaces. If the computer is connected to the internet while the program runs, VCDS will attempt to flash official firmware onto the clone cable. This mismatched data corrupts or "bricks" the device.

This error usually indicates a conflict between the VCDS software version, the loader version, and the interface's firmware, often triggered by an accidental software update.

: The loader (e.g., version 9.2) might not support the specific chipset (like ATMega162 or STM32) in your particular cable.

: Launching the original VCDS software while connected to the internet can trigger an update that the loader cannot handle, potentially "bricking" or locking the cable. Firewall Interference
