I have removed the EGR valve and cleaned it out with Carb cleaner then refined it, once refitted I have left the vacuum hose off ( plugging the rubber hose with a Golf tee to stop the vacuum being lost) this prevents it from opening the EGR valve.
You can buy stainless steel through pipes to replace the EGR valve from eBay, but as the 3.0 d engine is no racing engine I guess the original orifice must be good enough. So probably a waste of money.
Note. When removing the 4 cap head Alan screws that secure the EGR valve place a rag underneath, as you will drop the screws unless you have a magnetic Allan key

I have done the EGR delete to both my X5's.
It does allow the engine to breath easier - if combined with a K&N lifetime air filter, & makes a small difference in power & economy, but does add a bit more torque at low revs.
Typically, the EGR valve releases already burned exhaust gasses into the induction/inlet manifold.

A few things happen here:
The whole concept of a turbo INTER-COOLER is to chill the incoming air to the engine.....
The EGR valve pipes super-heated burned exhaust into the engine, which make no bloody sense at all re having an inter-cooler.
The EGR pipes burned exhaust into the intake, thus lowering the combustibility of the induction air - also make no bloody sense.

The concept of the EGR is to reduce emissions a fraction so the exhaust has a tinsy bit less % of nasties, buy fails to compensate for the loss of power it creates, thus the Go-Go pedal being used harder to compensate.

GET RID of the EGR valve, get a straight thru unit, blank off the exhaust end of the EGR feed, plug the vacuum pipe controlling the EGR valve.... and you're ready to go.

As a point of interest, my mate owns an MOT station, & we tested my latest X5 with & without the EGR valve fitted... There was no notable difference in emissions at all.

The two single most best things to do for emissions reduction before an MOT, is an oil & filter change & a cleaned/new air filter, + a dose of injector cleaner the week before.

I have a 190k car, with a clean emission status.
