What you'll need

A standard ENET cable

An Ethernet-to-OBD (ENET) cable connects the car's OBD port to your laptop. The same widely available cable used for BMW/VAG Ethernet diagnostics works — no proprietary dealer interface.

A supported supercar

Taycan (2020–2024) with the full feature set, programming included. 911 (992, 2020 on), Panamera (971 and 972, 2017 on) and Cayenne (9YA, 2017 on) with diagnostics, live values, actuator tests, maintenance and coding. Macan Electric and Cayenne Electric in testing, with diagnostics. One account across every platform.

Run a full control-unit scan in minutes, then read faults, watch live values, code or flash.
