The Ross-Tech VCDS HEX V2 is a powerful and versatile diagnostic interface for Volkswagen and Audi vehicles. This comprehensive guide delves into its features, compatibility, and why it’s the go-to tool for VW/Audi enthusiasts and professionals.
Features of the Ross-Tech VCDS HEX V2
The HEX V2 boasts a range of features designed for seamless diagnostics:
- Modern USB Connectivity: Utilizing a standard USB connection, the HEX V2 ensures compatibility with modern laptops and computers. A detachable USB cable with a proprietary locking mechanism offers secure connection, and can be temporarily replaced with a standard USB-A to USB-B cable if needed.
- Broad Vehicle Compatibility: The HEX V2 supports diagnostic communication with nearly all VW/Audi passenger cars from 1996 to current models. This includes vehicles using K, K+L, dual-K, and CAN protocols. Some exceptions apply, as detailed in the compatibility section below.
- Updatable Firmware: Equipped with a 32-bit microcontroller and updatable firmware, the HEX V2 stays current with the latest diagnostic procedures and vehicle updates.
- Clear Status Indicators: Tri-color LEDs (red/green/blue) provide clear visual feedback on the interface’s status and activity, visible from various angles.
- Integrated Software License: The HEX V2 includes an embedded VCDS software license, acting as a dongle and enabling software use on any compatible PC.
- One-Year Warranty: The device is backed by a 12-month warranty against defects in materials and workmanship.
VCDS HEX V2 Compatibility
The Ross-Tech VCDS HEX V2 interface connects via the standard OBD-II port found in most VW and Audi vehicles from 1995 onward (1996 for Audis). It also supports many models from 1990-1995 (Audis) and 1990-1994 (VWs) with the 2×2 data link connector. However, there are some exceptions:
- Volkswagen Routan: This re-badged Chrysler vehicle does not utilize VW diagnostic protocols and is not supported.
- Lamborghini: Requires the Ross-Tech HEX-NET interface for diagnostics.
- Early TDI Engines: Some 1991-1994 Audi TDI engines with 240bps ECUs may have limited compatibility.
Computer Requirements and Extensions
For optimal performance, Ross-Tech recommends using the HEX V2 with a computer running Windows 7 or newer, with at least a 1 GHz dual-core processor and 1 GB of RAM. While older systems might function, they are not officially supported.
The included cable is approximately 6 feet long. For longer reach, Ross-Tech offers a tested and approved 16-foot Active USB Extension. Passive USB extensions are not recommended. A 3-foot OBD extension is also available to keep the interface away from the driver’s area. For desktop PC users, the wireless HEX-NET interface might be a more suitable option.
Registration and Resale
Most interfaces purchased directly from Ross-Tech are pre-registered. Reseller purchases require registration within 10-15 uses. Registration is done online via a utility included with the VCDS software.
While the HEX V2 allows VCDS use on any compatible PC, product support is limited to the original registered user. Second-hand buyers need to re-register the interface for $99 to receive support.
Software and Driver Installation
The HEX V2 works exclusively with the latest version of Ross-Tech’s VCDS software. It does not emulate a serial pass-through interface and is unlikely to function with other diagnostic software.
As an HID device, the HEX V2 generally does not require specific drivers. However, an INF file included with the VCDS installer addresses potential power management issues in Windows 8.1 and later.
Conclusion
The Ross-Tech VCDS HEX V2 is the definitive diagnostic solution for VW and Audi vehicles, offering comprehensive functionality, broad compatibility, and ongoing updatability. Its user-friendly design and powerful features make it an essential tool for both professionals and enthusiasts.
