Hi All,
I’m new here, just purchased a 2008 XC90, Petrol, 3.2lt.
When the car heats up and is idling I am getting a loud whistle noise... anyone experienced this themselves?

Yes it's an easy one if it disappears when you take the oil cap off then you need a breather box/pcv very easy to replace on the 3.2lt

Ok, so I should remove the oil cap when I hear the noise and see if that fixes it and if so, get a breather box?
timbo
Yeah if it's the pcv then you will feel quite a strong suction/vacuum acting on the oil cap as you remove it

Ok perfect, I’ll give it a whirl tomorrow and see what happens

G'day Tim,
Thanks for your help on this, it seems it was the issue. I've ordered the new part so should fix it. Appreciate your help
