E90 Cooling Fan

[diesel78sg]

Hi folks,

My radiator fan is often on high speed mode even though the weather is cooling.
Any idea what is the problem?
What sensor is faulty?
Thanks.

I hv the same problem. There is no loss of coolen judging by the dipstick in the expansion tank. Been wondering if is normal..

My worry is that, if it is on high mode continously, it is bound to breakdown and overheating will quickly take place.. and then what??
