Update on 12v draw: Subaru tech can see it happening

Just wanted to update folks on the situation described here: https://www.reddit.com/r/trailseeker/s/jXUnehjvDo

Out TS has been in the shop for the second time. We had to have it towed out of our garage because the battery was too dead to jump start it. (The tow truck had to drag it, leaving some rubber on the driveway.) It's been in the shop for five days. They had to order a new (same kind) battery and install it, then they started testing it.

We had already eliminated all apps, including Subaru Connect, from our phones after the first incident. The tech took our phones both times and looked carefully at them so he could certify to Subaru we had done that. We did not cut off the DCM but we told the tech that was our next plan of action. He agreed it would be a good idea, but wanted to go through the specific steps from Subaru, in order, to better determine exactly what was causing the issue.

We were surprised to get a call today saying they can actually see the parasitic drain occurring. They have a call in to Subaru HQ for guidance on what to do.

I guess we'll see what happens next.
