F25(N52) Engine Whining Idle & Running - Crankcase?

Hello,

Recently got a 2011 X3. Drove about 500 miles and now it has a whining sound when the car is idling \ running

The research I have found so far is that the sound is cased by the Crankcase Ventilation valve or the breather.

A good amount of suction occurs when the car is idling and I undo the oil cap. So this is definitely the case from what all i have collected.

Anyone have any ideas as to what all to check to try and isolate which part of the CCV system it could be before I drop 375$ on a new breather?


Thanks,
Derek

This happen to me last year. Something similar. Haven't had problem since.

A cheap fix maybe found in this forum. Diaphragm replacement(?) (Didn't read whole forum!)

Worth a shot maybe if it doesn't go away
