Isn't that the battery vent pipe? It vents the hydrogen produced during charging away from the battery/fuse box etc. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Check around the throttle body/rear of plenum chamber for any loose pipes, not sure about the 4.4, but on the 4.2 there is an air pressure sensor that can blow off with age.
