Where is the tool kit on a BMW 330i?

my wife has a 2006 e90, and today i was looking for the toolkit (as sparse as it is, there should at least be a towhook) and i cant find it!

granted, her trunk is so full of junk it might be somewhere obvious, but i looked at the trunk lid (where my 5 series has one) and nothing there.

also looked at the compartment in the center of the trunk, and there is just a plastic tub for storage.

where should i be looking? i know she has run flats, so i dont expect anything other than the tow hook and maybe a screwdriver (we are in the USA), but i cant even find that.

thanks
