    On a TD4 yes if so you can remove it and clean it with some carb cleaner, but always best to clean the manifold and EGR at the same time, I have just done four manifolds ready for our meets starting this weekend.

    You'll need to unplug the MAP sensor to remove the inlet manifold. There's little point in replacing the MAP unless you're cleaning out the manifold at the same time.

    I presume you mean for the turbo.

    If you look through the cut out in the drivers side inner wing you will see it. Small black thing with 3 small (6-8mm) pipes going to it

    if so .. be a pic in post no.1
    https://www.landyzone.co.uk/land-rover/td4-lack-of-power-at-70mph-fixed.77147/

    can be seen - worked on - through the offside wheel arch
    and .. from under the vehicle just behind .. and left of .. the wheel
    easier methinks to work on it from underneath ..

    Thanks all I’ve got to the bottom of it all was an electrical fault so now I just need to find out where I can get a new plug from as need to splice some cables together. I’ve done a temporary repair with an electrical connection block

    I managed to find the loom in my shed, therefore I took the opportunity to dissect it so each plug and connection was separate, the plug you are after is the Turbocharger boost temperature sensor right< with two wires red/white brown/grey. as opposed to the turbo boost pressure sensor, (MAP) which as three wires connected to it.

    Drop me a message if you need the plug

    That's a 2 pin Female Junior Power Timer Connector Plug. They are common and cheap. But make sure you get all the plug components needed. Amazon have them for about £5 for the kit.;)
