I'm relatively new to the forum and after reading your post, I can agree with some, that you are in need of a BC Powder. Get past the negative and think. I spent twenty years in the military working on technical bulletins for field use.

The major information comes from the manufacturer. Then we spent months re-writing their specs that someone on the flightline could understand at 0300 hours. Guess what, if the flight line crew chief doesn't call and tell you that it's all B.S., then you have performed well.

Feedback is the key. If the Subaru tech doesn't report the problem with the FSM, then Japan doesn't (or in this case didn't) correct the problem, then you end up with a frustrating set of FSMs. Sorry to be the bearer of bad news. Good luck with your diagnostic problem.
