Hi guys can anybody identify the part in this link?sorry i dont know how to put pics on here,it keeps failing.in the picture,the filter you see housed in plastic,well the plastic is open at the bottom,so no liquid passes through this filter,it just seems to suck air into the housing via a pipe in the top.

Ignore this part....it is a small air filter...actually a small vacuum filter. The Lower end goes nowhere.
On the 2.5 CRD the EGR valve is opened and closed by vacuum coming from the vacuum pump driven by the cam belt.

The vacuum goes three ways...to the brake servo, to the air-vent control inside the cabin and to the vacuum solenoid for the EGR which is what your picture shows. The little filter below it is there to stop any dirty backflow air getting into the system.

The ECU determines at certain stages when to open the EGR valve to allow some exhaust gas to be directly funneled into the intake valves...to diminish air pollution and keep the Bunny Huggers happy.
The solenoid is activated by the ECU and vacuum is applied to the EGR valve.
On the 2.5 and early 2.8 CRDs for Export, the ECU does not check if in fact the EGR actually does open or close...it only measures the solenoid valve for a short circuit or for an open circuit.
You probably hear a long hissing noise coming out of the solenoid filter after turning off the engine...this is normal.

Most CRD owners go to great lenghts to disable the EGR as throwing hot sooty air unfiltered into the intake valves is not good for the engine. Fortunately for owners of the early CRDs such as yours and mine...it is easy to disable the EGR.
All you need to do is block one of the pipes at the solenoid....the easiest thing to do is to pull off the small outer pipe from the solenoid....screw a small self-tapping screw into the plastic openening and replace the pipe over the screw so it is out of sight. I have done this simple modification and get much better open-road performance. :D

It's a boost pressure solenoid filter or at least that's what it would be on an 05/06 2.8L CRD. On those vehicles it's hooked to a black plastic vacuum reservoir behind the passenger side (left side as you view the engine bay from the front) air filter box. That vacuum system drives the variable vanes on the turbo. It's supposed to be changed every so often but mine stayed clean for 45K miles.

Not sure what it filters on the earlier export models but it can be replaced by any similar size gas filter simply by cutting some vent windows in the bottom side if an OEM one is hard to find or pricey.
