A2141 minor liquid damage, U3100 TOP port dead. Periodically boots to 20V ~1A on other USBC ports

Just wondering if anybody has seen this issue. I'm assuming that all of the CD3217's are semi functional for the chips to request 20V from the PSU.

This unit had some soda spattered up into the side vent. I ultrasonic cleaned the board, now getting this weird sometimes requesting 20V behavior, then it goes back to 5.2V ~ 25mA The U3200 jack cycles.
I'm hoping this is just an issue with some components between the TOP Jack and U3100 and not U3100 itself.

Not seeing anything unusual on thermals just some of the power supply inductors getting warm when it's requesting 20V, only minor corrosion was observed around U3100 and U3200, minor darkening around the fuses near U3100/3200, neither are open.

I've gotten a little further on this machine.
I discovered that the diode drop for PP5V_S4_X_USBC is around .498V instead of .188V.
That would leave me to believe that several of the pins on U3100 may be open or internally something may be open on that chip?

After re-flowing around the U3100 and the area the soda had corroded I was seeing that the diode drop changed to around .336V.
I got the laptop to boot on the U3100 USBC port and got to the log in screen and thought great and left it to charge overnight.

The next day I came in to look at it and it was no longer booting, it was stuck at 5.22V 0A on all inputs. If I held down power I'd get a brief 20V then back to 5.2V
Connecting to the DFU port while running apple configurator instead of seeing the box which says "DFU" in large letters it says "RECOVERY" and Apple Controller underneath.

Running Revive gets it to start powering up and showing the Apple logo with progress bar, then it goes blank and goes back to 5.22V

I'm assuming that I still have an issue with a CD3217 since that appears to be the only place that would provide the diode drop?

XW3501 I assume is just the path for voltage sensing at U3500?

My next step will be to attempt to remove reball and reflow U3100 unless someone else has any suggestions or insights into this issue.
I don't have a donor board atm so I don't really have another option.
