N54 water pump intermittent 2E83 + 2E85 but drives fine

The 2E83 2E85 codes are the popping up intermittently after the horrific Voltage Regulator failure. I replaced the VR and it starts and runs all normal.
I got 83k miles on this water pump now. Got 178k miles total. 2nd pump failure.

2E83 being pump low power mode and 2E85 being pump communication problem.
I checked with Inpa and both occurs at the exact time.

Should I replace it or leave it as is and take chances?
And if I do replace it hopefully the codes won't come back.
Because something tells me they might come back anyhow.
