So look at the Live Ships Map
and adjust it to the port at Bremerhaven and see what ships are docked. In my case I saw the TOPEKA.
The line Wallenius Wilhemlmsen transports a lot of BMW's. From their web site, I could then look at the schedules
and drill down into the TOPEKA.
Days later after figuring this out, my CA emailed me with the shipping info - there is usually a few days' delay for this to get through the BMW system.
Hope this helps.
