I have a 04 X5 4.8is I would like to do the transmission adaptions i would also like to be able to read codes and modules. I do a lot of automotive work and i know how to fix cars but I don't know what software i need. I do know how to rip it, burn it and I have read that this installation is a little more complex. I'm not sure what windows version works best. I have used Vagcom in the past on windows 98 but it would not work on windows vista.
