Default why does audi need 2 temperature sensors? cant one do the job?

i have an AEB engine and i noticed i have both the blue and black temperature sensors right next to eachother, why would that be?

also my temp guage was going all over the place rendemly between 70-105 inaccuratly with both connected, i disconnected the black one and the car wouldnt start with just the blue one, i disconnected the blue one and wallah the temperature readings are steady and working fine

my question is why do i need two of them connected? would it be safe to drive with the blue one of the hook?
