Oil sender unit on E220 111 engine?
Also the engine runs on temp 80 but it goes up and returns so the thermostat seems to be working okay, and the top hose is hot and the bottoms cold as it should be.
It’s just had a main dealer service and the engines dry and quiet so I’m not too worried. But my old W123 230CE temp was always around the third mark and my C180 ran much hotter and it’s got the same type engine?
