There are plenty of mistakes in his endgame "course" and most of them are taken from other books, he did not even care to check. If I were you I would look for this position in "Basic chess endings" by Reuben Fine, my intuition tells me there is a good chance Pandolfini took it from there. I do not know how strong your engine is, but I recommend "Test your endgame ability" by Speelman and Livshits (it is difficult for weak humans and most likely it is also difficult for weak engines), anyway test positions are not the best way to test an engine (they say something only if your engine misses very easy ones).
