The Hex V2 Cable, an intelligent dual-K plus CAN USB interface, is the go-to diagnostic tool for Volkswagen and Audi vehicles. This powerful cable allows you to access and troubleshoot your car’s systems with unparalleled depth and accuracy. Let’s delve into its features and capabilities.
Key Features of the HEX V2 Cable
The HEX V2 cable boasts a range of features designed for seamless diagnostics:
- Universal USB Compatibility: The HEX V2 cable connects to any modern laptop via a standard USB connection.
- Broad Vehicle Coverage: Compatible with nearly all diagnostic-capable VW/Audi passenger cars from 1996 to the present, supporting K, K+L, dual-K, and CAN protocols. Some exceptions apply, see compatibility section below.
- Detachable and Replaceable USB Cable: Features a proprietary screw-locking mechanism for secure connection, but can be temporarily replaced with a standard USB-A to USB-B cable if damaged.
- Future-Proof Firmware: Equipped with a 32-bit microcontroller and fully updateable firmware, ensuring compatibility with future vehicle models and diagnostic software updates.
- Clear Status Indicators: Tri-color (red/green/blue) LEDs provide clear visual feedback on the cable’s status and activity.
- One Year Warranty: Backed by a 12-month warranty against defects in workmanship or materials.
- Integrated Software License: Includes an embedded license for VCDS software, acting as a dongle and enabling installation on any compatible PC.
Compatibility of the HEX V2 Cable
The HEX V2 cable connects via an OBD-II connector, standard in most VW/Audi vehicles from 1995/1996 onwards. It’s also compatible with many models from 1990-1995 (Audi) and 1990-1994 (VW) equipped with the “2×2” data link connector.
Exceptions:
- Volkswagen Routan: Not compatible due to Chrysler-based architecture.
- Lamborghini: Requires a HEX-NET interface.
- Early TDI Engines: Some 1991-1994 Audi TDI engines with 240bps ECUs may have limited compatibility.
Computer Requirements for VCDS and HEX V2
For optimal performance, a computer with at least a 1 GHz dual-core processor, 1 GB of RAM, and Windows 7 or newer is recommended. While older systems might function, they are not officially supported. Windows 8, 8.1, and 10 are fully compatible on sufficiently powerful hardware.
Extending the HEX V2 Cable
The standard 6-foot cable is suitable for most uses. However, active USB extensions are available for longer reach. Ross-Tech recommends their 16-ft Active USB Extension. Passive USB extensions are not supported. A 3-ft OBD extension is also available to keep the cable away from the driver’s area. For desktop PC users, a wireless HEX-NET interface might be a more suitable option.
Registration and Resale of the HEX V2 Cable
Interfaces bought directly from Ross-Tech are usually pre-registered. Reseller purchased interfaces need registration within 10-15 uses. Registration is done online using a utility included with the VCDS software. While the HEX V2 functions as a software dongle, 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 cable requires the latest version of the VCDS software. It does not emulate a serial pass-through interface and is therefore unlikely to work with other software. The HEX V2 is recognized as an HID device, usually not requiring a specific driver. However, an INF file included with the VCDS installer addresses certain HID power management issues in Windows 8.1 and later.
Conclusion
The HEX V2 cable provides comprehensive diagnostic capabilities for VW and Audi vehicles. Its versatile features, broad compatibility, and user-friendly software make it an essential tool for both professional mechanics and enthusiastic car owners. For in-depth diagnostics and troubleshooting, the HEX V2 cable paired with VCDS software is the ultimate solution.
