Engine Compartment Fan
I’ve been driving my ‘04 C4S around Florida for the past few days and, even after a fairly spirited drive, the cooling fan doesn’t come on at stoplights or when I pull into the garage and shut it down.
The temp has been in the ‘70’s. My 04 Carrera’s fan would come on frequently in the summer in Indiana. But the temps were probably 10 degrees higher.
Problem or not?

Maybe it is because I have never made too much city and the car gets good refrigeration.
I think that there is a one warning light in case the engine bay fan doesnt work

Ok. Thanks guys. I was thinking it might not have been warm enough down here.
My other one would kick on in the summer after coming off the interstate—not even flogging it. Wondering if that car was triggered at too low a temp. Oil temp is fine on the current car.
Thanks again!

The engine compartment purge fan rarely comes on.
From the service manual...
"Switch-on conditions for engine compartment fan (this fan pulls air into the engine compartment) The engine compartment fan is switched on when the engine compartment temperature is > 176 degrees F or the coolant temperature is > 216 degrees F.
After-running of engine compartment fan
If the ignition is switched off and the engine compartment temperature is more than 140 degrees F, the DME control module remains in readiness for another 20 minutes. During this time, the engine compartment temperature is retrieved every 10 seconds. If the engine compartment temperature is > 185 degrees F , the engine compartment fan is switched on for 20 seconds. If the engine compartment temperature is still > 185 degrees F after this time, the fan remains on for a further 30 seconds."

Ok, of course this happened AFTER I started this.
After crawling through the near gridlock of snowbirds in downtown Naples, I pull in to park at a restaurant and, ta dah!—I hear the fan running. It was just that much idling after running at 60 mph downtown to trigger the fan.
Thanks all—good input as always.
Temps crept up to the left side of the 8 in 180 but no higher.

ETA: Murphy, I have had the fan run after shutoff in the garage after some spirited driving on my old one but I have a pretty good stretch of cool down time driving into my neighborhood here in FL. Great info—more numbers for me to geek on!

I don't think mine has come on in the garage since I replaced my stock spoiler with the Taco spoiler.

You can test the sensor with a heat gun, infrared thermometer (and I use a heat shield).

I know! My buddy who warned me about the in-season traffic was utterly unsympathetic to my plight last night.
Hopefully heading to Marco this afternoon to watch the Colts/KC game (IF AA scheduling leaves me alone!).
