Can anybody tell me, where is the Water temperature sensor situated in B200 model from 2012 (W246 / 243)?
My problem is, that often when I start the engine in the morning, the water temperature indicator goes to 80 degrees C in a minute and shortly afterwards the temperature indicator fells down to 40 degrees C.
I suspect it is a loose wiring at the temperatue sensor, as a reading from an OBDII adapter shows the same temperature variation.
Any other suggestions for the 'crazy' reading of unrealistic temperature reading?
