I’m not sure exactly what you mean by “log on” but you don’t need to login or register to use the WW website. I used Internet Explorer (v8) (it doesn’t work with Chrome) and then went to this link
On the right it says Track and Trace and then underneath there is an “All Users” button with a picture of an open padlock. Click this. It opens a new window (a popup window, so if you don’t see this window popup, turn off your popup blocker for this website and try again).
Then copy your full 17 digit VIN into the Quick Search Cargo ID field and click the Track button. I used to see a “No records found” message (in red) and now I see the status screen that you can see in my first post on this thread.
Sorry if you’re already doing all of this and it comes across as very patronising! Hope this helps.
My dealer is still yet to inform me that my X3 is now in the Atlantic.
