Default Rear Diffuser

The rear diffuser (thing that essentially surrounds the exhast tips) on my 2007 S-line A4. is not bolted to the car. There are two brackets that are attached to the diffuser, but they are not attached to the car itself. I need to get under there are take a good look but is this an easy fix? I'm not the original owner, so I'm thinking perhaps the bumper was removed and these not re-attached?

Thanks.

Don't know if this link will help you out, but it does show two brackets in the bottom photo that seems to be connected to something.

Thanks. Seems mine are broken off where the bracket meets the bumper underneath and inside. Audi, in its infinite wisdom, has riveted this fragile part to the bumper (as opposed to a Torx or allen screw). So there's no way to replace the bracket without removing the outer cover of the bumper itself. This is going to take some ingenuity.
