This is what I got off another site.
My dealer gave me a production status code, what does it mean?
Below is a list of BMW's production status codes:
037 - Order is at BMW NA
087 - Production week assigned
097 - Order sent to BMW AG
111 - Order accepted at BMW AG
112 - Order scheduled for production (last opportunity to make changes)
150 - Production started
151 - Body shop started
152 - Paint shop started
153 - Assembly started
155 - Production completed
160 - Released to distribution
180 - Waiting for export dispatch
193 - Arrived at port of exit
194 - Selected for shipment
195 - Shipped from port of exit
196 - Shipment arrival - ETA
The other things you may have to get from another member of this site. If your build date has changed for earlier date more power to ya.
I wish I could be so lucky.
