0W40 is allowed for hot climates but 5W40 is also a reccommended spec so it may be worth trying that as the next step
and yes 100 degrees C for oil temp is fine it when its over 125 you have to worry
now if a drain, refill with 5W40 and a fresh oil filter doesn't help I'd say the next step is to plumb in a mechanical pressure gauge to confirm if the oil pressure really is low and its not just a faulty sensor
if its really low then the next step should be to remove the sump and replace the oil pump
do you still need help?
