Hi I have a 2014 C250 CDI. The temp normally stays around the 87-90C mark.
However recently its been getting to that mark, and after about 40 minutes of driving it'll slowly drop to 75-80c mark, then slowly raise back to where it was. This happens on almost every journey now, sometimes multiple times depending how long the journey is. It can be at high speed or low speed, so its not dependant on engine load.
An idea what this could be?
