The K+DCAN USB Interface is a high-quality diagnostic and programming cable designed specifically for BMW vehicles. It enables full communication between your car’s OBD-II port and a PC or laptop, allowing users to perform complete diagnostics, coding, and ECU programming using BMW factory-level software.
This interface supports both K-Line and DCAN protocols, covering a wide range of BMW models from 1998 to 2016, including the popular E-series and some early F-series vehicles. With this dual-protocol capability, it ensures compatibility with both older and newer BMW systems, making it a versatile tool for workshops, tuners, and BMW enthusiasts.
When connected to software like INPA, NCS Expert, WinKFP, ISTA-D (Rheingold), or Tool32, users can read and clear fault codes, perform ECU adaptations, code new modules, and even reprogram vehicle control units. It also supports live data streaming, service interval resets, and complete system diagnostics across all vehicle modules.
The K+DCAN USB Interface uses a reliable FTDI FT232RL chipset, ensuring fast and stable communication between the car and computer. It connects easily via USB, requires no external power, and works with Windows 7 / 10 / 11 (32-bit or 64-bit). The cable is compact, durable, and easy to use—ideal for professional garages as well as DIY users who want dealer-level access to their BMW’s systems.
