Turbo Vent Valve question

:behindsofa:

Hi folks...Fitted the vacuum reservoir and replaced the pipes with 4mm silicon.
I also decided as the weather was dry(ish) to replace the pollen filter and the Turbo Vent filter which came as part of a service kit.
The vent valve (Part no. PHB000450), which looks like an inline filter in a nylon case, was found at the rear of the engine (TD4), clipped to another pipe.
I noticed that the "Filter" has only one end connected-at the large diameter and the other end had a small length of rubber hose around 10mm long just pushed on and is open to atmosphere....is this normal, or should the other end go somewhere ??
I have searched Microcat and PHB000450 is not shown for the TD4, only the L322.

And I thought the P38 was a challenge !!!!

Yes normal, it vents the vacuum to the air to allow the VNT mechanism on the turbo to return to its normal position.

Thanks for the prompt reply...much appreciated.
