I've recently noticed that the radiator fans on my 2014 63 S (W218) are turning on immediately upon a cold start-up. Is this normal? Does anyone know where the fan relay(s) is located?

Thanks!

I may be wrong, but i believe on my 2010 e63 the fans run for about 30 seconds, maybe less, on start up. The car idles a little higher for a bit then everything goes to normal, this all only lasts a minute at most

Mine does the same, you live in the same climate as I do. You'll see that when its -10 out.
