macbook pro M1 a2338 820-02020 water damage

[gizaha]

Small water damage, cleaned it.
Shorted CL002, i removed it carefully with soldering iron, now it has voltage.
5v instant 180ma and then 100ma stable. I didn't found cycling voltage nor shorts in the motherboard.

I don't have pp5v_s2 because uc300 does not get enable pin from u8100 (it gets VIN). pp5v_s2 is not shorted, nor enable pin line.

PP3V3_S2 OK
PP3V3_S2_UPC OK
PP1V5_VLDOINT_MPMU OK
PP3V3_AON OK
PP1V8_AON OK
PP1V25_S2 OK
PP1V8_S2 OK
PP1V8_S2SW_VDD1 OK
PP3V8_AON OK

u8100 did not have corrosion at all so i give it a little chance of fault.
All fuses ok, both type-c tested on both sides.

Any ideas?
