Can it be there are TD4 models without a turbo vent filter??? I have the 2005 model and have searched for days (literally) but cannot find any. And believe me, I have spent hours searching for it spread out over two weeks and I have groped with my hands behind the engine for so long I believe my car feels violated.

As I was sure there had to be a filter I never asked about it, just kept looking, but now I found a picture of where the filter should be (or better, where the hose should be connected) and now I notice I have one less hose connected to where it should be.

I found a picture on the internet (uploaded it) where it says pipe number three goes to the filter. I just made a picture of the part in my freelander and there is a small black box on the place I expected the pipe that connects to the filter to be.

Is it just me or did someone replace the hose / filter with that small black box? Or did I lose it for some reason? Or am I more of an idiot then I thought and am I looking at the wrong spot still?

Additionally, the next time I get it on a bridge (or how it is called in English) I am going to look from the bottom up. Maybe I see something from that side. But I am starting to feel someone replaced the hose + filter with something else.

All the f1s I've ever serviced have had the normal filter (Looks like an in line fuel filter), if it was me I would refit an original pipe and filter at least until you know what the box is, any chance of a picture of it I'm curious?

I will try to make a better picture when I get to it from below. I think it is the best way to take a better look at the part. In the second picture (the one from my car) in my first post you can see it, but it is somewhat in the distance. I believe the small black box you see there is at the location the pipe should be.

Ah my apologies I didn't see that it was in the second PIC, aye it is a queer looking thing

From your picture what you have got fitted is the ERG solenoid, the black box on the side is the filter. There was a small issue going back a couple of years when L/R had a small batch of ERG solenoids that they labelled as turbo solenoids.
I think the solenoids are the same in operation but on the turbo solenoids they fit the third outlet to get the filter up out of the way.
