My m5 gets too hot at idle. I have flushed the radiator, replaced the thermostat, and replaced the fan clutch. Anybody know anything about the auxilary fan temp switches?


You can check the switch(es) in a pan of hot water with a voltmeter. I'll bet your low speed resistor on the fan is T/U. Jump the switch terminals with a piece of wire while the ignition is in the run position. If low speed doesn't work, then the resistor is bad. About $30-40 at the dealer.

How many switches are there and where are they located?
