Part 2: Installing and Configuring Actia PUD API Driver for Porsche PT3G VCI

The Actia PUD API driver is essential for enabling communication between the Porsche PT3G VCI and Porsche diagnostic software, such as PIWIS III. If you are using a pre-configured VNCI PT3G HDD, these drivers are already set up for plug-and-play use. However, if you’re using original or third-party PIWIS III software, manual configuration of the VCI driver within the PUD API is necessary.

It’s crucial to verify that your device is recognized as PT3G_VCI and not as a generic 6154a or other J2534 VCI, to ensure correct driver application.

Download the necessary PIWIS OEM driver, which includes the Actia PUD API Driver and a required patch, from the following link: PIWIS OEM Driver. Alternatively, you can download the Actia-64 driver separately here: Actia-64.7z. Extract the downloaded zip file to a convenient location on your computer.
