    This article will guide you how to correctly install VAG-COM 409.1 KKL USB cable on Windows and VCDS software.
    CAUTION Using VAG-COM 409.1 KKL:
    In our experience, we don't recommend depending on VAG-COM 409.1. Because it's functionality is extremely limited. In addition — you'll need to pay extra $97 to upgrade free VCDS-Lite software to full version. And even if you do upgrade — it can only scan vehicles made up to year 2004.
    For that reason we recommend to get the complete VAG-COM 2020 cable with original, unlocked and full version of VCDS software from Ross-Tech™ — by clicking here.
    STEP 1: Download and Install VAG-COM KKL 409.1 Drivers
    (DO NOT connect cable to your computer yet. Only do this when you're instructed below.)
    Start by downloading the VAG-COM Driver Pack 1.
    Here's how to install on different Windows versions..

    Windows Vista, 7, 8, 8.1, 10:

    Uncompress the file. Double-click on 'Install.exe' to install the drivers. When complete — plug in cable into any USB port on your computer and wait for automatic installation to complete.
    If install is successful, move onto Step 2.
    If installation fails, see below: Troubleshooting: If Drivers Failed To Install

    1. Uncompress the file. Double-click on 'Install.exe' to install the drivers.
    2. Plug cable into any computer's USB port.

    4. Select 'Install the software automatically'.
    5. After the installation is complete, click 'Finish'.
    6. 'Found New Hardware Wizard' will start once again because there are two drivers for this cable.
    7. Go through the same steps as explained above to install this second driver.
    If install is successful, move onto Step 2.
    If installation fails, see below: Troubleshooting: If Drivers Failed To Install

    Then:
    1. Click: Port Settings

    Cable should be plugged into computer.
    1. Start VCDS-Lite software.
    2. Click 'Options' button.
    3. You will see 'Select COM Port' box. Select the 'COM Port' number as explained in Step 2.

    6. You can now connect other end of cable to car. Turn on ignition. And you're ready to start diagnosing!
