Data is being logged @ 50hz so the bus isn't being saturated at K-line speeds.

Wow, that is odd to me....
Are you seeing any CAN Bus activity? I would expect to see activity using service $21 or $22.

How is your CAN bus sniffer set up? Pass through or listen only?
Are your filtering out every CAN ID below 0x700? -OR- just allow -7E0 & 7E8

Since your Z is from 2017, I would be surprised that they would use the slow K-Line.
BUT maybe they are using the K-Line with the NDSIII protocol? I don't know...
