This is my first post on this board, but I'm not a novice, have done some extense research on the subject and found virtually no consistent answer. I'm owner of Facebook Group "Pajero TR4 Brasil" with over 2600 members, and I'm a proud owner of two Pajeros, a TR4 2.0 4G94 engine(brazilian version of IO) and recently acquired Pajero Sport 2005 2.8 TDI 4M40 engine.
After replacing the diesel filter I notice a little hose coming from a component that, based on its appearence, seemed to me a solenoid valve. Two hoses coming from it and one (lower) was loose. I could find a similar piece on ebay as a "Turbo Boost Vacuum Solenoid", but has no sucess on identifying such component on my Workshop Manuals.. Does anybody know this piece, what it does and where this little inferior hose should be connected?
Thanks in advance!

Real pic of the component. The filter on the upper left is a FRAM diesel filter, only for location pourposes. The inferior hose is loose....

and this is the piece I found that resembles my pic
