It seems clear that the TU is
Region Specific, in that there's a TU1 and a UK TU1 each with different Media ID's and only the UK TU1 could be applied to my UK version of the game when I tested with XeXTool.
I don't see much point in opening up my 360 to connect the DVD drive when a) I still won't have the UK TU2 and
I've got an ISO made from the original disc on my PC from which I can extract the xex and test patching it with the .xexp from the TUs (which is what I've been doing).
If the original xex was borked I doubt that the game would work or that the UK TU1 would successfully patch it.
.xexp patching can only go so far - a load of TUs need far more than this and it does get messy.
You'll need to obtain TU2 for media ID 4C0C6DA0 in this case. http://xboxupdates.24.tl
only has a TU2 for a different ID - if you have a live 360, connect it with your AC II disc and download it. There's not much else you can do unfortunately.
