To get the best performance and avoid "Interface Not Found" errors, follow these steps for a clean installation:

VAG Dash CAN is a specialized diagnostic tool designed to communicate with the instrument cluster (dashboard) of vehicles via the CAN-bus protocol. Unlike standard OBD-II scanners that only read engine codes, this software allows for deeper "EEPROM" level access. Read and write the immobilizer PIN code. Calibrate or reset odometer values after a cluster swap. Add or delete transponder keys to the immobilizer system.

Use a high-quality shielded USB-to-OBDII cable. Cheap, unshielded clones often fail during data transmission.
