[THE335]

G'day all,

Some help please.
The radiator fan on my 2010 N55 335 has started to do strange things!
Oil temp gets to about 90 degrees then the fan comes on full blast for about 6 seconds, off for about 2 seconds, on for 2 seconds, off for 2 seconds, then on for 6 seconds. This pattern just keeps going, it doesn't stop.

I have tried to search but cant seem to find anything similar.
Can someone please help?


Thanks.

mine is E92 325i, I got this situation occasionally, but it doesn't really like yours, mine is suddenly on full blast for an extended time even just start up the car.
I was like, does it really that hot to have the fan in full blast? I haven't really come across with a car that needs to have its fan in full blast mode like that to cool down the car previously...was a bit nervous...

not a common issue with the water pump in 325i, right?
