    For those more familiar with under the bonnet, I presume that this is a diagnostic port, and not something that has been unfinished ?

    sorry but for some reason the picture is upside down !

    It's an air flow/pressure sensor on the plastic intake leading to the throttle body, totally normal, it's clipped into a plastic mould on the intake pipe.

    As already advised, given the location, maf or boost sensor, looks like latter tbh.
