I don't know. i've opened up engines after sitting in a shop for many many
years and have never seen water (or any other) contamination at least that
was visible. My Jettas were "never" (my quotes because no VW ever held oil
for that long) supposed to undergo transmission oil or transmission fluid
changes.
The reason I would change oil in an engine is if I did not know what I was
working with, no matter what the circumstances.
Does anyone know for sure about oil being hygroscopic? About it turning
acidic? And I am talking about for certain, as in information from a
chemist.
