I just went through same experience with my 2013 335 order - the online info on my build was incorrect until the vehicle entered production. All along the way the dealer was confirming he sees correct info in his ordering system, and the day it went production, the online info has updated to correct one... The web site is well known to show incorrect info up until last moment, so I probably wouldn't worry much.
