Hey mgruber, yes it is a combo TCU/Assist module. Here's the info as it appears on the label:

84.10.9132711-01
169211 11
USA 25.01.2007
Continental
BMW EVEREST IBUS US
SW: 37 HW:50
BT: 0019C08C9171
PK: 0128
ESN: 102 - 15457718
AUN0008064

I believe the part number is the first number (84.10...). I know PK Is the passcode key. I'm not sure what the other numbers mean. Maybe someone else can chime in and shed some light.

Interestingly enought, the work order refers to the unit as "RMFD TELEMATICS CTRL" -- I wonder if RMFD means remanufactured...
