Before purchasing registration, test that the software communicates properly with all systems in your car. Connect the interface to your vehicle's OBD-II port (located under the dashboard on the driver's side) with the ignition on (engine not running). Run a test scan to verify connectivity.

If you plan on owning VAG vehicles long-term, investing in an official Ross-Tech HEX-V2 Enthusiast interface is highly recommended. While more expensive upfront, the hardware serves as the license key itself, unlocks the modern, fully-featured VCDS software, supports both old K-Line and new CAN-Bus cars, and includes official tech support.
