I'm thinking not enough air flow though the EGR valves, or stuck throttle ( if the 2.2 has one, 3.0d does for EGR purposes so it can reduce the airflow through the throttle body, and add if from EGR at low power/idle )

How about changing more modules to make a full set ( I'm thinking at least VIM ( steering lock), BCMs, and KVM ) as well as the PCM and IPC. Then use the keys from the donor car too.

IPC and PCM are part of the PATS so I doubt you can use them without at least reprogramming the stored VIN

It looks like the 2.2 does have a throttle too, so that could be sticking too as far as I understand they are pretty much use exclusively in combination with the EGR, so if they stick shut when the egr closes, or egr doesn't open as expected when the throttle is shut it'll choke the engine.

Sorry when I said BCMs I meant both BCM, and BCMB.
It it a facelift i.e. does it have DX23-14B476-?? BCM an DX23-14D628-?? BCMB for which the VIN could be edited as long as you have a suitable BDM programmer, though it you have the bought the whole donor car, it's probably quicker just to swap them.

I think that spring is for the EGR cooler (i.e a separate flap / value that diverts the gas via the cooler or bypasses the cooler ), there'll also be the EGR valve itself ( which controls how much gas is recirculated). On the 3.0d at least, the EGR valve is electrically controlled, while the cooler is vacuum operated with spring return ( vacuum line has a solenoid in )

Have you run the air path test ( if it applies to the 2.2 ) as in https://www.jaginfo.org/posts/2858603/

It's a test rather than setup routine I mentioned, I think it's full name is something like "Turbo EGR and Air Path Dynamic Test" The OP of the thread I linked above, can probably tell you it's correct name. There is a video of someone running it, ( but I don't claim to understand the non-english text in it ) -

Yes 600km is going to make it difficult, is Michael in the UK then? ( just wondering given your mentioned potentially acquiring a donor car from the UK )

I'd be kind of reluctant to blame injectors ( but can't claim to be experienced enough to rule it out completely), as presumably they are being controlled just fine at higher RPM, and it'll be the same control circuits, wiring etc.

I'm much more leaning towards something air path related, or a sensor that only provides significant input at low revs. I wonder if it still runs without stalling at higher RPMs all the way to warmed up ( i.e. after it switches to closed loop operation ) - Just theorising it might go to closed loop operation sooner at idle.
