I have connected the driver seat on the K_CAN and all works fine! (positions, heating, lumbar, bolster and memory)
I still need the CAN cable to remove the airbag warning.
To connect the K_CAN, I confirm the connector:
Socket terminal MQS 0.2-0.35 MM˛/SN 61131383776
(I had some difficulties to connect them because my wiring was too big for the holes)
