Good day,

Without actually taking my oil filter canister apart, I can't be positive, but I believe it is an anti-flow back valve or flow regulation valve of some kind that sits in the bottom of the filter canister... My X5 is actually due for an oil change soon... I will take some pictures when I do... This isn't the first time I have seen this issue...

Cheers!!
