It's the one from the outside panel (behind left headlight) to the filter box. From memory, it comes in two parts. A brackety type part on the panel behind the headlamp and the pipe from there to the filter box.
I seem to recall putting the car to someone to do work as I was unable to due to injury. Looking at it, I see other parts have been left un replaced too, like a pollen filter and highly likely the diesel filter
I did the diesel & air filter last night and am about to do the pollen filter (what a stupid place to have it
) and a drop link (advisory in the mot).Anyhoo, I can't see to find the correct pipe on the bay. I keep getting the MAF to filter box pipe or pipes for unrelated vehicles such as a 2.0 Grand Picasso

Anyone got one? There's a lack of them in scrappies around here and I imagine Citroen dealer will want both legs
Thanks all.

EDIT:
I found something on the bay.
I didn't notice it looks like the pipe is in two parts, one bendy part (that fits on the headlamp panel) and a rigid part that goes to the filter housing.
Now I think the rigid pipe comes in two parts, but the picture I was looking at shows a square aperture where it enters the air box whereas the one on our C4 is round and facing upwards... I imagine I could simply pull it out of the air box
That was what was throwing me 
Here's the link. I need parts 6 and 9....
Thanks all
