Now i'm already 90% certain the SSD is dead on this one but if there's anything else I can check let me know!

820-01041A received with liquid damage around U9000 and U9080 - cleaned up all and:

Board Charges the battery USB C meter negotiates to 20V but does not start no fan spin.
All voltages present up to the power on stage - PP3V3_S5 is the first missing voltage and PPBUS is at 12.31V
SSD voltages present 2.5V, 1.8V and 0.9V
PMU_ON_OFF_L drops to 0v when button pressed.
Trying a revive from Apple Configurator 2 - it sees the device in recovery mode, proceeds to attempt the revive gets about half way then fails with Error 10 0xA (10)

Well this story at least has a good ending - I tried the revive on another Macbook - Apple configurator said it needed an update which I said yes to - it closed Apple configurator then offered the revive or restore through Finder. I chose Revive on finder and this time it went all the way through and the Macbook powered up with all the customers data still intact. So if anyone else has a similar issue then it's well worth trying a different Macbook and to do the revive through Finder instead of Apple Configurator!

Probably T2 firmware got corrupted as a result of the water damage!
