That is part of the plastic linkage holding open the lower flap (fault code)
note plastic pieces in LL port and UL port - on pic also notice fans regarding clearance challenge !
The small pieces were all in the head intake ports ; the large flap piece fell out of the original intake when I tipped it on its end!!
"open heart" surgery !
left crank case ventilation component in place (lots of plastic).
this assembly came off with the original intake ; note hoses strategically disconnected. Also, note the connection to the connection above photo (o-ring).
Different view / angle ; same component as above.
New intake manifold install complete ; with new HP fuel pumps. Just before start up ; fuel lines ready to be observed / checked for leaks! Bottom of photo: LP fuel pump SENSOR (top of pump) PN: 06E906051K Audi
PN's for head gaskets, cam followers, O-rings (throttle body).

Note proximity of Core support relative to front of manifold location !
