i was told (this last week), but not sure i believe, that when they update the software on these z4's they update ALL the software for all the modules (ie, they no longer update individual modules). In other words, they are given one large update file from bmw these days. If true, then this could be the reason for the change you noticed. It could also explain why you go in to get something fixed and something totally unrelated breaks....
