I don't know that one is available, just read that from time to time BMW updates things like the transmission software that some dislike in the 328. I sometimes think my 328 does some odd shifts and was planning on checking with the dealer if an update is available for it. Wasn't sure if whatever they update would erase the tune, or your tune erases what they would have done. Is the software updates for the transmission a separate file from what the AA tune is changing? Pardon my noobness, just not sure how all this works.
