P0599 code HELP! Thermostat circuit too high

Hello guys.







Sure hope you can HELP me on this one.







I have a 325 XI 2004 e46 and i have been having this problem for the last year or so.







Check engine light is on, and it gives me code P0599, Thermostat heater control circuit high.







I have changed my thermostat and the hoses, but i still get the code.







For the last 2 months or so, my prestone level goes down at about 3/4 cup per month. Therefore, my radiator light goes on as well.







There is no sign of radiator leakage, we have checked everywhere!







Anyone have sugestions on what i should do?
