Another function is the "Bong" when the outside temp. reaches + 3.5 degree C. and that you should drive carefully.
Have not yet checked in the wiring diagrams if even the windshield heater (the area for the wiper blade heating) and the door lock heater are also somehow connected to the temp. feeler in the front.
In addition you will not get any audible warnings from the check control, low oil level, low oil pressure, wash water low level etc.
Would not eliminate it.
Fix the probs, that's the right way. This little thingy is like a watchdog for your and 'barks' when your car is not feeling healthy.
