Cummins/Ram and Duramax/GM both use Continental NOX sensors, now the question is which one has a long enough wire and which one has a connector that works with BMW. The NOX sensor cannot be separated from the control box.
It's hard fro pictures to really see if the connector is the same or not, but they should all have 4 pins: CAN+ CAN- Ground and 12V...

Both of these were 5 pin on the controller to body side. I got resistance on pins 3 & 4. Was the same on both the old and the "new" sensor. The sensor itself had 7 wires going to the control box.
