			Has any one actually tried to swap a TCU in a pre March 2004 build of the X5?  Any one done the swap of TCU in an X5 and actually gotten it to work?  I was considering trying it but I can't return the module if it does not work.  All the anecdotal evidence seems to be in other cars and not the X5.  I know there was a specific wiring issue with the X5 that prevented the early adopters that thought they had bluetooth from actually installing a TCU.   The only known option is still a ULF.  Anyone have any feedback?Thanks!
