In the latest VCDS diagnostic systems, HEX-V2 and HEX-NET, you can choose between the Enthusiast Versions (3 VIN / 10 VIN limitation) or the Professional version (no VIN limitation).The Enthusiast versions are especially suited for newcomers or amateur users. They are much more affordable due to the limited number of diagnosable vehicle identification numbers (VINs). An upgrade to the Professional version is possible at any time.The Professional version is especially suited for workshops and professional users because an unlimited number of VW, Audi, Seat, Skoda & Bentley vehicles can be diagnosed.The HEX+CAN-USB interface is only available in the unlimited Professional version (without VIN limitation).
