Hi Matt
It looks like you are missing the fresh air intake. This runs from the middle of the box section above the radiator towards the nearside, then drops down to the air filter input. It's mostly plastic, with a small flexible section at the air filter end. Not essential, but maybe useful if you ever drive through a flood.
Can't see anything else missing, but it is a bit like playing a "spot the ball" competition !
The pressurised hose from the intercooler to the throttle body looks a bit odd, as though it has been wrapped in plastic tape which has suffered from the heat ? The standard hose is rubber, mostly covered in a woven nylon "sock" which presumably helps it resist expanding under boost pressure.
I think your wiper arm on the driver's side is set too low. Mine measures 47 mm on the offside, taken from the blade rubber to the bottom of the glass/lower windcreen seal. The other end of the driver's blade ( nearest the van centre) measures 70 mm, so the blade is angled almost but not quite parallel to the base of the windscreen. Maybe your arm has been bolted on one spline off ?
