VNCI PT3G Porsche Diagnostic Interface

The VNCI PT3G is a Porsche diagnostic and programming interface — essentially a vehicle communication module (VCI) that connects your car to diagnostic software such as PIWIS3 (the OEM Porsche software) via USB, Wi‑Fi or LAN. It functions like an aftermarket replacement for the original Porsche PT3G/PT4G interface that Porsche dealers use.

Key Features

✔ Plug‑and‑play compatibility with original PIWIS software drivers (no major modification required).
✔ Supports a wide range of Porsche models/ECUs.
✔ USB, Wi‑Fi and LAN communication options.
✔ Can replace the original part at a fraction of the price.
