1.6 BGU Idling problems when warm - diagnostic help?

[Passat my07]

Maybe you booster is faulty. Do you get any reserve assisted pumps of the pedal after you turn the engine off?

I get 2-3 pumps before boost is exhausted, unless the engine was acting up when I turned it off. Does that sound like a problem?

New info:
I checked the measuring blocks while the car was running poorly today. IAT was ranging from 125-132*c.
The IAT sensor works normally. Reads ambient when cold, warms up to expected temps (sub 80) when running properly.

Would a stuck open EGR cause high temps at the intake, or am i on the wrong track?

Edit: EGR Valve was causing the issues
EGR passed adaptation when cold so I'd ruled it out. Today I checked when the engine was running bad and it failed adaptation.
Once the engine was cooled I cycled the valve to make sure it was closed and unplugged it. Car ran perfect on a long mixed drive.

In short, the lightly sooted EGR valve jams up when hot.
