Sorry for all the beginner questions, but I have one more question

! Today, I connected my Passat 3C's combination instrument to the gateway using an interface, set the bitrate to 500000, and selected "Listen Only." As long as I don't start the vehicle, everything works fine, but as soon as I start it, the speedometer works normally for about 2 seconds, and then the entire combination instrument CAN bus fails

. This happens even when I only have the interface connected without a laptop. Somewhere in this forum, I read that someone desoldered two resistors when using the interface alone }!
Regards,
David.
