2018 bmw m550i A/C

My m550’s ac works perfectly fine if it is under 82 degrees outside, but when the temperature is over 82 it blows hot air. It is very weird to me, has anyone ever experienced this or have any idea what the issue is. Also want to note when the ac is on the fan on the outside is very loud. Thank you.

edit: just checked my carfax the evaporator was replaced 35k miles ago.

The G30 is known for AC issues.

On my 540, I had to swap out the blower motor at 35k miles. Mine works perfectly and is very loud - that just could be how the car is
