Gaawrsh !! I just can't help myself, if I try to help you :laugh: -
First, your ABS CAN confirm which vessel (Istra Ace or Grand Ruby) it's on so you can get past that trauma - but as I told you, my bet would be the Istra Ace as its one of VW's most common and the Grand Ruby is one of BMW's ... I'll try to check it later this morning myself, as I know your ABS is somewhat limited to help.
As for tracking from port to Ohio - THAT is gonna be pretty OC AND not too easy unless the driver gives you his GPS beacon data - or better yet have the port enable your Audi Connect with your VIN, leave the ignition on the whole way (maybe the battery will last for a day) - don't worry they WON'T do this - they don't have the SIMs - it just sounded about as OC as anything ...
Once your car is released from Davisville, it's usually only 2-3 days to Ohio, so this is stress simply not needed. I mean really, perhaps you can get the driver to tweet every time he stops to pee or get coffee, or god-forbid, stop over at another Audi center on the way ...
