Since everybody else is posting about their cooling system problems, I'll chime in with mine. Becuase of a faulty relay connection, I've had some experience with an inoperative aux fan in the 240D. I've noticed that when the fan isn't working, the coolant temp quickly runs up to 105
at any road speed. When the fan is working, however, the coolant stays right at 90.
I would have expected more ram air coming through that huge upright W123 grill at highway speeds, but apparently it needs help from the electric fan. Does anyone think the cooling system has a problem?
And no, I'm not ready to sell this car yet.
