Any idea what a new thermostat and sensor should cost ?
Including install from an independant Mercedes shop ? As of today getting P0128 error. Engine water temp seems ok at 88 to 90 degrees C), (w/ outside temp 68 degrees F ) coolant level is good. I suppose it would be interesting to watch how long it takes for the engine coolant to get to 88 C after a cold start in the morning since that might indicate whether this is stuck thermostat or defective sensor. Presume either way one ends up paying the same to fix it.
