Also, when was the last time you changed oil? And what filter did you use?

I bought the car just 2 months ago and the dealer did the service as well. On the papper is showing that they have changed the oil and filter but I don't know what filter they used. |
I seen some people have a similar whistle noise when they didn't use a genuine bmw oil filter.
So could be that if they said everything else is fine and the air intake is not damaged.
