I'am in GA, where the temp is a hot 95-100 and very humid all the time. I am thinking about replacing the original thermostat with a 71 degree thermostat. Anybody ever replace a lower temp one and have any problems? Will it mess with the motronics or other sensoring devices such as fuel, temp, or air flow ? It is time for me to replace it and i want to use the lower temp one. TIA.. 92' 735i 78K.
