VCDS HEX V2 Enthusiast allows advanced functions for a limited number of vehicles, locking VINs to the device. Pro versions offer unlimited vehicles but share the same diagnostic capabilities. Regarding enabling predictive cruise control (often called ACC), VCDS can potentially achieve this if it doesn’t require communication with VAG factory servers. However, VAG’s protection protocols might prevent modifications.
A definitive answer requires a VCDS Autoscan of your vehicle to provide specific information. Locating someone in Italy with VCDS to scan your car would provide the necessary data for a more accurate assessment. Share the Autoscan results here for further assistance.
It’s important to remember that VCDS primarily functions as a diagnostic tool for vehicle repair. While capable of some coding modifications and tweaks, it’s not designed as a customization tool. Ross-Tech’s support for modifications is limited, as outlined in their Retrofit Policy: http://wiki.ross-tech.com/wiki/index.php/Retrofitting
