Peake Code keeps coming back '8C' looks like I'm going to replace the six month old thermostat. I'm assuming the heater circuit is bad again? Bsnl Wimax Hacking Tricks And Softwares. If I understand correctly, the car will run slightly cooler in a manual mechanical mode without this circuit functioning correctly. Is there any other thing I may be overlooking? Fan is working, and I checked all conncections. Temp gage is at 12, code came back immediatly after resetting? Could Peake be wrong?thanks in advance99 540iA Sport.

I have no experience with Peake - but I assume that it is somehow set to the engine and model year that you have because the codes do change over time. Assuming that the code is correctly identified then it simply means that the DME is detecting some fault with that sensor circuit (getting a resistance reading that is out of normal parameters) or that the DME control circuit for the thermostat is itself defective. You are NOT correct about the affect. Your engine normally operates at about 108C - where it is most efficient. Under heavy engine loads, or if the coolant temp goes above about 118C then the DME will activate the heater in the thermostat so that it fools it and therefore it opens earlier to lower the temperature.
