HELP Coding??

[hp8300]

OK I have a Black X5 3.0i 2002 which I had to bring back to live.
Allready changed Fr suspension and resolved some issues with the engine and transmission left DSC and GM3 modules.
I have aquired a GT1 software and the connections but now I can't get the car to recognise the DSC. I understand that it has to be coded into the car but when I go to coding/programming and select DSC than I've tried entering the last 7 digits of the part# => I get no dice.
Is there someone who can help me out here.

Cheers!
