Funny you made this thread - I was wondering the same thing about 3 hours ago and found this site with a quick google search. Works excellent:
https://www.parts.bmwgroup.com/webet...r/callback.jsp
If that link doesn't take you to the page, follow
this link and follow the instructions to manually enter the UN and PW provided on the page. It will take you to the above link.
Enter last 7 vin digits, hit options at the top, and you'll get your info. On the the top of your full info page you can also hit the "+ Vehicle Information" to get your...ehem...vehicle information.
