I guess it was my luck. The guy on Genius line insisted he only need the Vin # not the production number when i offered. Ok, it has been only 6 days since the status was moved into production begins, will wait a few more days and hopefully that get moved into exterior body assemby...If you have a VIN you're in the production queue, but the reason they can't find anything out about it is because technically that VIN isn't a built vehicle yet, it's just been assigned to BE built - that's why you use the production number!
The genius lines can be clueless, but if you call them, ONLY give them the production number ("I don't have a vin") you can usually get your build day and a detailed status, but you have to get the right person.
I'm guessing you got the VIN from mygarage.bmwusa.com? Basically it means you're vehicle is status 150, i.e., in the production queue and/or being produced. Typically - depending - that's take 7-10 days to see any updates (the vehicle takes 1 day to get built, but the time between 150 and built is usually ~10 days ... plan on 14.
But, again, if you're getting the vin from the mygarage site, then just be aware it's not yet an active VIN and won't work as input on any BMW system (e.g., if you try to download your owners manual by inputting your VIN it won't recognize your VIN)
