Just bought a V50 2.0D 2004 with a little issue.. :,(

No turbo boost bellow 2000 RPM, above the 2000 RPM it does boost normally (feels like the VTG is not working at all but the rest is fine)

When I got around to inspecting it i saw that the vacuum hose from below the inlet manifold(where the 2 hoses are coming from a black plastic unit??)
The one that splits in a T piece is plugged (after the T where it goes down) with a screw and the hose coming from (if you standing in front of the car) left bellow is not connected at all
when I connect these properly (like a mates V50) the turbo does nothing at all..
does anyone have any idea what is plugged or de routed (sorry for my grammar... can't help it, I’m Dutch :P)

just did a diagnostic check with a mates tool;
U0301Software Incompatibility with ECM/PCM
U0380 GlowPlug/Heater Circuit "A"


i think this tells me that the car was chipped and that my glow plug is bad
but no faults seen regarding boost regulators or stuff like that


Will post a picture if the text is to blurry..

ordered a service manual from eBay, but still waiting on that..

if anyone got any leads!! (a picture of the vacuum route would also be very helpful)

 

these are the hoses that when i connect them the turbo does nothing at all


does anyone got any idea where this is for?;



if you see something that should be different here let me know; (and what does the thing do that i higlighted)
