I did the battery trick to delete code couple times to see if it's just a rare hiccup, but it always came back. The symptoms included a fluctuating idle and slightly different throttle response since it's related to the intake cam I guess. The problem gave me a nightmare as it had been purchased within a week and gave me a problem.
I took out the solenoid unit, cleaned it with a brake cleaner and on the connector which had some oils sipped in it. After this remedy and battery reset (unplugging and plugging back in), it hasn't had thrown the code at all and the idle sits at 650 without fluctuating like before. Even after another spirited driving, it's been fine for the last couple days.
While I ordered a solenoid, o ring and the backup ring, I checked the other solenoids, and a couple others had a similar leak but not as severe as the one I cleaned up.
Hopefully the one I ordered was manufactured after the date mentioned in the document. Since I used the Toyota part number, it was SU00307806.
Sorry for no pictures. I didn't take them when I cleaned them.

I went to the Subaru dealer to pick up the solenoids for my ‘15 FR-S. As long as you know the part number for the old solenoid that you have, and get the replacement part that supersedes it, you should be good.
Just make sure to clean the electrical plugs with electrical parts cleaner before you connect them back up. The TSB actually tells you to replace the plug as well if it has oil in it, but I don’t think that’s absolutely necessary as long as you can get all the oil out with the cleaner.
