    2012 X3 - oil thermo buzzing sound?

    I am getting a buzzing noise which is coming from this unit here...

    According to REALOEM - I am thinking this is Part # 11427573051 Oil Thermostat - however I am having a hard time understanding why I would be getting a buzzing noise? I used a stethoscope and I am 90% sure its coming from this part (check alternator, checked Idler).

    Anyone familiar with this part?

    UPDATE

    Still bugging me - so I pulled the oil filter cap off and the unit came out in 2 pieces? The cap is separated from the stem that goes inside the filter housing - most likely at engine idle this was the buzzing noise I heard.

    The stem snaps back into the cap - but it surely wont be tight (or it wont stay very tight) - Is this normal - or do I need to order a new one?
