Weasel,
With lots of help from Jose and I mean lots of help I was able to get my GT-1 going.
I have a couple of question and hopefully you will have the answers.

I ran DIS on my 2006 X5 and got a TCU Telematic Control Unit failure.
Diagnosis bus error unknown control module variant.
Fault Number 200.102

I ran the “Coding/Program” portion of the DIS Program Car Memory and received the following:
A fault occurred during determination in the Control Unit TCU
Measures: Recode Control Unit TCU. If the coding index is not correct – Update ZCS/FA

I would assume you can recode the TCU under the programming section of the Coding Program?
I didn’t go any further then to read out the error code at this time.
