The VCDS HEX+CAN USB interface has been a reliable tool for VW/Audi diagnostics for years. However, with advancements in vehicle technology, Ross-Tech introduced the VCDS HEX V2 interface. This article clarifies the key differences between the older HEX+CAN and the new Vcds Hex Usb Can V2, focusing on performance and future compatibility.
Both the V2 and the HEX-NET, which the V2 is based on, utilize the same 32-bit microcontroller. This results in a significant speed increase when diagnosing CAN-based cars. For older vehicles using K-Line communication, the speed improvement is negligible as the module itself limits the communication rate.
A crucial reason for the upgrade is compatibility. The older HEX+CAN interface struggles to communicate with all modules in 2016 and later model year vehicles. The V2 addresses this issue, ensuring comprehensive diagnostics for newer cars. If you currently only work on pre-2016 vehicles, upgrading is not immediately necessary.
Eventually, the HEX+CAN and previous generation interfaces will no longer receive software updates. While Ross-Tech plans to maintain a legacy version of VCDS software for older interfaces, new features and support will only be available for the current generation VCDS HEX USB CAN V2. The timeline for discontinuing support for older interfaces remains undetermined but is estimated to be at least a year or more away.
The primary difference between the V2 and the HEX-NET lies in the latter’s Wi-Fi capability and onboard storage. The HEX-NET also includes VCDS-Mobile, enabling diagnostics using any device with a web browser and Wi-Fi connection, including smartphones, tablets, and computers. The V2 focuses on providing a robust wired connection for reliable diagnostics.
