    Yes the VIN is transmitted on the CAN bus. But not over and over. I believe it will be seen in ARBID 0x610. Was this mentioned before? I'm not sure. Anyway I looked at my notes and found this statement
    "Appears that there is a 0x610 request from the ABS in a remote frame (RTR bit set). Response from the IKE Contains VIN." Or in other words I observed a remote frame request from the ABS computer and the IKE sent a 0x610 response containing the vin. If memory serves I sent the remote frame from one of my devices and the IKE also responded with the VIN. It could be that other modules could send a remote frame request and perhaps other modules would answer. Not sure. Didn't see the need to chase that. But I don't think the DME asks for the VIN.

    Hope that helps.

    As far as I can tell, the DME doesn't broadcast its VIN over the CAN-bus.

    Indeed, it does not broadcast it. Just looking for a way to read it into the DME if itīs already available.
