About K+DCAN USB interface

K+DCAN cables connect a Windows PC to BMW and MINI vehicles that diagnose over K-line or D-CAN. That is the E-series generation, before the move to Ethernet.

Supported vehicles

  • E-series BMW and R-series MINI, roughly 1998–2013 depending on model.
  • Most cables have a switch that bridges OBD pins 7 and 8. Older cars need the pins bridged; later E-series (around 2007 onward) need them open.
  • F, G and I-series cars use an ENET cable instead.

What it can do

  • With INPA, ISTA, NCS Expert, WinKFP and Tool32: codes, live data, coding, adaptations and module programming.

Strengths

  • Cheap, and the standard tool for E-series coding.

Limitations

  • Needs the free BMW tools (EDIABAS and INPA) set up separately, which can be fiddly.
  • An FTDI-chip cable is recommended.

OBD4 does not provide software, licences or downloads.
