I noticed the electric fans coming on for short time even on winter morning. I think this is part of self-diagnose the car performs on each start.
I am not familiar with the CLK, but just weeks ago I fixed constantly running fan on older MB model. Turned out the temperature switch on top of the thermostat shorted and was sending constant signal of hot engine. That was separate circuit from temperature gauge.
I wonder where you live to find 4 mechanics in the row, that knows nothing about the 10 years old cars?
