yeah mate its just below it . if you take the airbox of, you mite be able to get to it better. should be easy to find it will be a black pipe about 10cm long just push it on the end and shoudl be fine .
as for the egr , whilst airbox is of and car isnt running i would unclip it , its to the left of that little pipe thing were the metal charge pipe goesinto .might be a green clip with like a shield round it . unclip that and take it for a test drive
