For automotive enthusiasts and professional mechanics specializing in Volkswagen and Audi Group (VAG) vehicles, the right diagnostic tool is not just an accessory—it’s a necessity. Enter the Ross-Tech OBD2 cable, specifically the HEX-V2 Intelligent Dual-K plus CAN USB Interface, a powerhouse designed to bring dealer-level diagnostics right to your laptop. This interface isn’t just a cable; it’s your gateway to deeply understanding and maintaining your VW, Audi, Skoda, or SEAT.
Key Features of the Ross-Tech HEX-V2 OBD2 Cable
The Ross-Tech HEX-V2 interface is packed with features tailored for comprehensive VAG diagnostics:
- Broad Compatibility: This Ross-Tech OBD2 cable works seamlessly with virtually all diagnostic-capable VW/Audi passenger cars from 1996 to the present day. Whether your vehicle uses K, K+L, dual-K, or CAN protocols, the HEX-V2 is engineered to communicate effectively. It also maintains compatibility with many older models dating back to 1990.
- Modern USB Connectivity: Utilizing a USB connection, the HEX-V2 ensures compatibility with modern laptops, making it a versatile tool for today’s technicians and car enthusiasts. The detachable USB cable, equipped with a secure screw locking mechanism, offers reliability and can be temporarily replaced with a standard USB-A to USB-B cable if needed.
- Advanced Internal Architecture: At its core, a modern 32-bit micro-controller and updateable firmware ensure the Ross-Tech OBD2 cable remains at the cutting edge of diagnostic technology. Regular updates keep it compatible with the latest vehicle models and diagnostic procedures.
- Intuitive Status LEDs: The tri-color LEDs provide clear visual feedback of the interface’s status and activity from almost any viewing angle. This instant communication helps users understand the diagnostic process at a glance.
- Robust Guarantee: Ross-Tech stands behind the quality of the HEX-V2 with a 12-month guarantee against manufacturing defects, offering peace of mind in your investment.
- VCDS Software Dongle: The HEX-V2 includes an embedded VCDS license, functioning as a software dongle. This allows the full VCDS software to be used on any compatible PC, offering flexibility and convenience for multi-user environments or workshops.
Vehicle Compatibility and Considerations
While the Ross-Tech OBD2 cable boasts extensive compatibility, it’s important to note a few exceptions:
- VW Routan Vans: These re-badged Chrysler vehicles utilize different diagnostic protocols and are not fully supported.
- Lamborghini: Lamborghini models require the Ross-Tech HEX-NET interface due to their specialized diagnostic systems.
- Early Audi TDI Engines: A small number of 1991-1994 Audi TDI engines with 240bps ECUs may not be fully supported.
For the vast majority of VW-Audi Group vehicles from 1990 onwards, the HEX-V2 Ross-Tech OBD2 cable provides unmatched diagnostic capability. It easily connects via the OBD-II port found in most 1995 and newer VWs and 1996 and newer Audis. For older 1990-1995 Audis and 1990-1994 VWs equipped with the “2×2” data link connector, adaptors are available to ensure compatibility.
Optimizing Your Diagnostic Setup
To ensure optimal performance with your Ross-Tech OBD2 cable, consider the following recommendations:
- Computer Requirements: For best results, Ross-Tech recommends a computer with at least a 1 GHz dual-core processor, 1 GB of RAM, and Windows 7 or newer. While older systems might function, they are not officially supported.
- Cable Extension: The included 6-foot cable suits most laptop setups. If you require additional length, Ross-Tech offers a tested 16-ft Active USB Extension. Standard passive USB extensions are not recommended. An OBD extension cable is also available to keep the interface conveniently placed away from footwells.
- Desktop PC Users: For desktop PC setups, the wireless HEX-NET interface may present a more convenient alternative, offering similar diagnostic power without cable length constraints.
Registration, Resale, and Software
- Registration: Ross-Tech often pre-registers interfaces purchased directly. Interfaces from authorized resellers require online registration within 10-15 uses to maintain functionality.
- Resale: The HEX-V2 acts as a VCDS software license dongle, allowing software use on any PC. However, Ross-Tech support remains with the original registered user. Re-registration for second-hand purchases is available for a fee.
- Software Compatibility: Always use the latest VCDS software version with your HEX-V2 Ross-Tech OBD2 cable to access the most current features and vehicle compatibility updates. The HEX-V2 is specifically designed for VCDS and does not support emulation for other software.
- Driver Installation: The HEX-V2 operates as an HID device, generally not needing separate drivers. A device-specific INF file, included with the VCDS installer, addresses specific HID power management behaviors in Windows 8.1 and newer.
