What part do I need (see pic)

It's the bumper of a VW MK5 polo but is there a specific name for the plastic clip thing underneath that is falling off this car?

Front bumper splitter probably. Most Indy garages could probably re-attach it for you

Just pull it off, most Polo's have damaged them.

Front downforce on a Polo is everything.
