For automotive enthusiasts and professionals delving into vehicle diagnostics and ECU tuning, the blue VAG KKL OBD2 cable with the FT232RL chip stands out as an essential tool. This cable is specifically designed for vehicles within the Volkswagen Audi Group (VAG), including Volkswagen, Audi, SEAT, and Skoda, offering a cost-effective yet powerful solution for communication and diagnostics.
Why the FT232RL Chip Matters
At the heart of a reliable VAG KKL cable lies the chip that manages the USB to serial interface. Among various options, the FT232RL chip from FTDI is highly regarded for its superior performance and features compared to cheaper alternatives like the FT232BM or CH340.
- Enhanced Configuration: The FT232RL chip provides internal options for configuring its operation, offering greater flexibility and reliability in different diagnostic scenarios. This is a step up from older chips like the FT232BM which lack these advanced configuration capabilities.
- FTDI ChipID Feature: A key advantage of the FT232RL is its support for the FTDI ChipID feature. This unique identification is increasingly important for software compatibility and accessing advanced functionalities, particularly with tools like NefMoto ECU Flasher, which leverages this feature for premium functions.
- Software Compatibility: Cables equipped with the FT232RL chip ensure broad software compatibility, working seamlessly with various diagnostic software packages designed for VAG vehicles, including older versions of VAG-COM (VCDS) and open-source tools.

Recommended Blue VAG KKL OBD2 Cables
While numerous VAG KKL cables are available online, selecting one with the genuine FT232RL chip is crucial for optimal performance and future compatibility. Based on user experiences and recommendations within automotive communities, sourcing from reputable sellers can increase your chances of receiving a quality cable.
Historically, eBay sellers “easybid2000” and “alpha-bid” were noted for providing reliable blue VAG KKL cables equipped with the FT232RL chip at competitive prices. While seller availability may change, looking for cables advertised with the FT232RL chip from sellers with positive feedback is a sound approach.
Important Note: The market is unfortunately also filled with lower-quality cables, sometimes using counterfeit chips or inferior components. User accounts have highlighted issues such as poor USB connector quality and even broken pins in some entirely blue KKL cables. Therefore, purchasing from trusted sources and verifying the chip is essential.
Checking Your Cable for the FT232RL Chip
Once you acquire a blue VAG KKL cable, verifying the presence of the FT232RL chip is a prudent step. Software tools can help you confirm the chip type and its features.
- NefMoto ECU Flasher: If you intend to use your cable with NefMoto software, version 1.6.1.0 or later includes a feature to detect and display information about the FTDI chip within your cable. Simply select the USB device in the software, and hovering your mouse over it will reveal details about the FTDI chip, including whether it supports premium NefMoto features. This is a direct way to confirm the presence and functionality of the FT232RL chip.

Ross-Tech Cables: A Premium Alternative
For users seeking top-tier reliability and comprehensive support, official Ross-Tech VCDS cables are also highly recommended. Notably, official Ross-Tech cables, with the exception of the older KII-USB model, incorporate the FTDI 232R chip (similar to FT232RL).
While Ross-Tech’s HEX-CAN-USB cable is officially stated to only work with their VCDS software due to its lack of COM port support, it is compatible with software like NefMoto, which communicates directly with the USB chip via the FTDI SDK, bypassing the need for COM ports. However, Ross-Tech cables represent a more significant investment compared to the budget-friendly blue VAG KKL cables.
Conclusion: Choosing the Right Cable
The blue VAG KKL OBD2 cable with the FT232RL chip offers an excellent balance of affordability and functionality for VAG vehicle diagnostics and ECU tuning. By prioritizing cables equipped with the FT232RL chip and sourcing from reputable vendors, you can secure a reliable tool for your automotive needs without breaking the bank. Remember to verify the chip using software tools to ensure you are getting the performance and compatibility you expect. Whether you are a DIY enthusiast or a professional technician, this cable is a valuable asset in your toolkit.
