The BMW K+DCAN OBD2 - USB (Switch) interface cable connects your Windows laptop via USB to the OBD2 port of a BMW or Mini. With software such as INPA, NCS Expert, Tool32 and ISTA-D, you can read out all control units, clear fault codes and code options.

The cable supports both K-Line and D-CAN. With the switch, you connect or disconnect pins 7 and 8: connected for cars with K-Line (up to approx. 03/2007), disconnected for cars with D-CAN (from approx. 03/2007). The USB connection runs via an FTDI chip, which Windows recognises as a COM port.

HIGHLIGHTS

✔K-Line and D-CAN — One cable for older and newer E-series models.
✔Pin 7/8 switch — No separate bridge or adapter required.
✔INPA, NCS and ISTA-D — Works with the well-known BMW software.
✔FTDI chip — Stable COM port under Windows.

POINTS TO NOTE

✕Not for F and G series — These require an ENET cable.
✕Driver required — Install the FTDI driver and set up the COM port.
✕Windows only — No phone app via this cable.
✕Software sold separately — The cable is supplied without software.

Applications and functions

The cable is intended for BMW and Mini specialists and DIY enthusiasts who want to read out or code an E- or R-series vehicle with a laptop.

Functions

  • Fault codes: Read and clear in all modules.
  • Live data: Sensor values in real time.
  • Coding: Adjust options with NCS Expert.
  • Service: Including CBS reset and battery registration.

Switch

  • Pins 7 and 8 connected: K-Line, cars up to approx. 03/2007.
  • Pins 7 and 8 disconnected: D-CAN, cars from approx. 03/2007.
  • Unsure: Try the other position if there is no connection.

How to use it

  1. Install driver: Install the FTDI driver on your Windows laptop.
  2. Set up COM port: Configure the COM port via Device Manager.
  3. Set the switch: Choose K-Line or D-CAN with the switch.
  4. Connect: Plug the cable into the OBD2 port; switch the ignition on.
  5. Start software: Start INPA, NCS Expert or ISTA-D.

Special features and capabilities

What makes this cable different from a standard OBD2 cable:

  • BMW protocols: K-Line and D-CAN via EDIABAS.
  • Physical switch: Connect or disconnect pins 7 and 8.
  • Wired connection: No signal drop-out during coding.

Compatible software and operating systems

The cable works with BMW software on a PC or laptop. Well-known programmes:

  • INPA and EDIABAS: Diagnostics, live data and fault codes.
  • NCS Expert: Coding of options and functions.
  • Tool32: Running individual ECU jobs.
  • ISTA-D: Comprehensive diagnostics and fault finding.

Operating system: Windows, with the FTDI driver. The cable then appears as a COM port in Device Manager.

Compatible vehicles

The cable is intended for BMW and Mini models with K-Line or D-CAN via the OBD2 port:

  • BMW E-series (K-Line): Approx. 2000 to 03/2007, incl. E46, E39, early E60/E90.
  • BMW E-series (D-CAN): From approx. 03/2007, incl. late E60, E90, E70, E87.
  • Mini R-series: K-Line or D-CAN, depending on the year of manufacture.

Not suitable for the F- and G-series; these use an ENET cable for ISTA and E-Sys. Older models with a round 20-pin diagnostic connector require a separate adapter.

Package contents

  • 1x BMW K+DCAN OBD2 - USB (Switch) | Interface Cable (Blue)
💡
Good to know: INPA often expects the cable on COM1. Therefore, in Device Manager, set the cable's COM port to 1 and the latency timer to 1 ms. This prevents most connection errors.
