Turbo/Intercooler bypass 300 TDi

Hi there folks.
On the D90 I bought the under pressure hose is disconnected from the bypass valve - so actually like setting it blind. The weak parts are the old hoses, that kinda collapse when the turbo wants air.
As I understand the technic, it shall mainly prevent the turbo charger from "pumping" when air density is changing - simply spoken.

My question: put the valve back into function or replace it with the kit to close it?

(At the moment I'm at about 10.2ltr/100km mainly done off road. And here where I drive, the temperatures are not changing that drastically.)

Thanks for any advise!

Bypass hose? Maybe a picture of what you are trying to describe would help.

You can buy a piece of steel plate that closes off the EGR. Google Rover TDi EGR delete

The question is more like: shall I close it or put it back into function?

If you are a green party member , you will repair it. If you are a CDU you will block it.

It is not required. It reduces NOx emissions slightly.

Green party? Jim: by coincident I've studied environmental engineering at the University of Hamburg; as per my experience the word "green" is used far too often for a lot of f* excuses or so called "innovation" ( what the heck that really means in real live nobody could explain to me to my satisfaction by now).
So: If I don't harm my engine AND reduce my consumption (direct CO2 and so on print), I give a f* about green parties. My 300TDi is a more environmental friendly Diesel than a lot of the 13l/100km "innovative" hight tech electronically controlled one-way-tins.... Ha!
