Reviving an old thread. I am looking for the easiest place to pick up CAN+ and CAN- without having to tap into the ECU. I am looking for a place in the interior of the car. I have checked the OBD2 port for CAN which is usually on 6 and 14 but it does not seem to be present. This is on an 2007 E90 335i. It is present on an M3. I also tried to find K-Line at the OBD2 port and that is not present as well. I know CAN+ is red/blue and CAN- is Red at the ECU.
I need this for data logging purposes.
