I have found that any component directly connected to the BMW motor, such as boost or IAT, operates on the 1 Mbps CAN bus. When I try to read this in some mode, the car freaks and starts showing errors on my infotainment screen. Others will not return data. Is there any way to listen to the data without the car knowing and throwing codes?
This is on a 2018 bmw F22 M240i
