2016 WRX, drains battery from full to dead in 4 days

[gawainx]

I'm trying to troubleshoot a parasitic drain in my 2016 WRX ltd (eyesight)
After some trial and error I've verified that the battery itself is good but the vehicle has a significant parasitic drain

I've been going at the thing with a multimeter but am a bit intimidated sonfsr about either hot pulling fuses or continually disconnecting the battery in short succession.

There's about a [email protected] load on the battery with the vehicle entirely off and no lights lit.
I've found that the ABS system is accounting for about 250 MA of that but not sure where the other ~160 adbornmal MA may be coming from yet.

How much would troubleshooting something like this likely cost me, especially with the ABS seemingly involved.
Any guidance or thoughts before I dump too much time into this or screw something up would be much appreciated.

Could this be related to this pending class action suit?
