Hey Jose-

You think you are confused! Get this, my TCU/Assist module part number isn't even in the BMW ETK ! And I can't find it on Realoem. So basically I have no idea about install dates. The sticker on it says Motorola and the build date is 6/12/2004.

You mentioned that yours is RFMD, which is a remanufactured part, but what I don't get is that I read somewhere in a BMW TIS bulletin that the TCU/Assist modules could not be reprogrammed and had to be replaced outright. So at least it appears that they can be remanufactured and recoded since that seems what BMW is doing.
