Official software contains built-in anti-piracy counter-measures. If the loader fails to mask the device signature properly, or if the VCDS application establishes an internet connection and contacts official remote update servers, it will immediately overwrite the internal EEPROM firmware of the clone cable. This process completely "bricks" the device, rendering the ATMEGA162 chip permanently unresponsive until it is manually desoldered and reprogrammed via an external ISP programmer.
