On a Freelander 1, it's possible to remove the EGR without any real problems, just get a good kit.
However many people prefer to keep it, and just clean the manifold every 50k miles.
For reference, a good quality EGR blanking kit costs about the same as a shiny new pattern EGR valve.

but never got as far as the manifold - besides, I need to get new gaskets in readiness.

As above…
Took mine off today - Jesus it was full of crud! Cleaned out as best as possible.
Got me thinking about just getting a EGR blanking kit - BUT, what is the general consensus on these?

Do you have to get the ECU updated, so it knows there is no EGR, or just unbolt the bejesus thing, put a blank in, and crack on?

Still undecided what to do about the EGR (leave alone / replace / delete)

If your EGR was anything like this one below, then your manifold and the MAP sensor attached to it will also be gunked up.

The seals gaskets are reusables' wipe then clean with a rag,

3

4

you want the manifold cleaned out as below.

5

6

Scrap most of the gunk out then you can jet wash the manifold out clean L5P delete kit.

When cleaning the manifold out the MAP sensor needs to be removed, and wiped clean, carb cleaner on a rag wil do the job, do not poke anything into the MAP sensor breathing hole.

10

I must change out at least 5 manifold and EGR plus clean MAP sensors at the meets we have each year, we have 6 meets per year, for the Rover 75 & a quite a few now own FL1 TD4 they have the same engine.

I fit either a cleaned out EGR or an original EGR gutted.

I do have a couple of gutted EGR for sale.

15

Your FL 1 TD4 will feel the difference one the above has been done.

If you install an EGR blanking kit, you’ll usually need to update or tune the ECU to avoid check engine lights or limp mode. Some cars can handle a simple blank without a tune, but for a proper and reliable setup, it’s best to have the ECU adjusted after blanking it.

Never ever had any limp mode or check engine light on any of the Rover 75 or Freelander 1 M47 engines that as had an original EGR gutted and fitted, also no ECU adjustments? maybe it just a USA problem who knows.

There is a gutted EGR on my F1, simply ‘fitted’. No need to update any ECU at all. Still absolutely fine.
There might even be a blank on my F2…

What's down that MAP señor hole? I just had one that was completely solid with gunk. I poured stuff down it to clear it several times but ended up very gently rolling a thin bit of dried grass inside it to pull the rest of the crap out. No offence to Land Rover but that is one **** design.

someone with a better brain maybe able to say how this actually works?

It uses a pressure transducer to monitor the pressure inside the inlet manifold. MAP sensors are generally pretty robust, as they're designed to handle much more pressure than the normal operation pressure.
They're not protected against objects being poked through the sensor port though.

Automatic car tyre pumps use a similar although less robust sensor monitor tyre pressure, turning off the pump at the preset pressure. Pressure transducers are also found in modern car wheels, so they can send pressure data to the car tyre monitor system.

Our Ioniq 5 actually gives the tyre pressure for each wheel in PSI on the driver's display if needed.
