Citroen Dispatch / Peugeot Expert 2004 2.0 HDI - Unknown lose hose off intercooler manifold pipe - Gully.Moy
Hi. I'm trying to sort out my old Dispatch as it has a few problems, most relevantly P0243 (turbo wastegate solenoid fault). It's a 2004 mk1 facelift 2.0 HDI RHZ DW10BTED+.

I've got a couple of damaged vacuum hoses which I obviously need to replace, but I also found a lose hose I'm not sure about. It's a narrow and short one that comes off the pipe linking the intercooler to the manifold. The large pipe (# 0382 Y4) can be seen in the link below. The disconnected hose attaches to the extrusion towards the top left of the pipe (intercooler side).

I've checked on Citroen Service box, and can find the main pipe, but nothing relating to the small hose in question. Any ideas where this is supposed to go? All of this is new to me.

Cheers
