Hi, I'm a newbie here, this is a great site!!

I checked the part number of TCU 84106965056 with the dealer, aND was informed that it was superseded by part number 84109132711....

Does anyone know the difference? I do have an 2004 (4/04) X5, with Assist but No Bluetooh. Like everyone else with an 2004 model, got the passkey code and everything but does not work. Wanted to upgrade and saw the post above to say that was the most updated TCU, however getting a different info from my dealer. I dont want to be stuck with an old TCU just because the dealer wants to get rid of it....does either one have Voice Recognition?

Help....
