MLB 820-00850 does NOT match boardview/schematic... any ideas?

i took in a 2018 mbp13 A1989 after a liquid damage and a serious moron opened it up.

several pieces are missing from the MLB, but one cannot be identified as it exists on the board (and the teardown photos) but NOT in the boardview or schematics. has anybody worked on this?

@reverendalc preliminarily it appears to be a 74AUP1T97GM IC Gate. Check the datasheetLow-power configurable gate with voltage-level translator and you may confirm by measureing on the solder pads. Check with Digikey.com or Mouser and see if they have the right package. The part itself is less than $1.00USD

You'll need to locate a more upto date schematic and board view. The one you have is clearly incomplete. The newer models have been harder to get and I've only found early drafts which are incomplete.

Yes it’s clear that this boardview is incomplete. I was hoping somebody may have this board to look at for me...
