Are you currently seeing this error message while trying to , or does it happen during the initial software test ?

Check which VCDS version you have:

Depending on whether your interface is simply blocked by software or completely bricked at the firmware level, use the targeted technical approaches outlined below.

The "Failed 2 New" error is a solvable problem. By methodically following the steps of a clean reinstallation, managing your antivirus software, and understanding your interface's hardware, you can overcome this obstacle and unlock the full diagnostic power of VCDS for your VAG vehicle.

When you use a VCDS clone, it requires a "loader" or "loader.exe" (sometimes associated with Kolimer) to simulate the presence of a genuine Ross-Tech interface.

Flash the correct Vendor ID (VID) and Product ID (PID) back to the chip.

Purchase a genuine Ross-Tech HEX-V2 or HEX-NET cable (starting at $199 for 3 VINs). You will never see this error again, you get live updates, and support.
