Adblue or not

[gmw65]

Hi all
I have just traded in a B6 for a 2011 B7, I cannot find any Adblue filler cap anywhere on the car, all online info so far says that if it's a bluemotion it uses Adblue. When I switch the ignition on the icon lights do not show any Adblue icon,, I've looked in the car's manual and it shows the filler to be under the spare wheel but there's nothing there except for the wheel securing bolt. I have a 2.0 Tech sport estate and am wondering if any of the early B7's didn't take Adblue. Can anyone shed some light on this please? Still getting my head around the B7 features, it's already tried to chat me up by suggesting we stop for a coffee.
