Perhaps I should remove that and see if cleaning is needed.

Air normally just gets compressed and decompressed in that line. So there is no signifigant air flow as such. It should be okay. You will know as soon as you drive the car.
It appears that over time some of the soot etc from the egr introduction to the intake manifold lodges in the manifold fitting specifically. Plus sometimes reaches the boost limiter. Since the time the line broke off there would have been air flow in that line with some of the egr gasses and soot etc. Was why I though to blow on it was a good ideal. The boost limiter could be directional. Is a possibility. When there is an obstruction it usually will be in the manifold fitting.
