Installing the VAG-COM 409.1 KKL Cable Drivers

Step 1: Download the Drivers

Locate a reliable source to download the correct VAG-COM 409.1 drivers for your Windows 10 operating system.

Step 2: Disable Driver Signature Enforcement

• This step is crucial for older cables that may not have digitally signed drivers.
• To do this, search for “Startup Settings” in your Windows search bar and select “Change advanced startup options.”
• Under “Advanced startup,” click “Restart now.”
• Once your computer restarts, navigate to “Troubleshoot” > “Advanced Options” > “Startup Settings” > “Restart.”
• Press the “7” key on your keyboard to select “Disable driver signature enforcement.”

Step 3: Connect the Cable and Install Drivers

• Connect the VAG-COM 409.1 KKL cable to your computer’s USB port.
• Windows will likely detect the new hardware and attempt to install drivers automatically. Allow it to proceed.
• If the drivers don’t install automatically, you can manually update them. Go to “Device Manager,” right-click on the unrecognized device (usually listed under “Other devices”), and select “Update driver.”
• Choose the option to “Browse my computer for driver software” and locate the downloaded driver files. Follow the on-screen prompts to complete the installation.

Step 4: Verify Driver Installation

• Open “Device Manager” again. You should see the VAG-COM cable listed under “Ports (COM & LPT)” as “USB Serial Port (COMX)” with a specific COM port number assigned to it (e.g., COM3).
• Note down this COM port number, as you’ll need it later for configuring the software.
