800 miles on car now...Engine/Car Whistle, dealer confused

[kennyisdead911]

hey everyone, we just got delivery of our new x5 and after a week or 2 of driving, we realized the car was making some strange noises. The car sounds like there is an aftermarket intake on the car (engine whistle, or some sort of sucking whistle).....well we took it to the dealership and they had it there all day today, 2 techs confirmed the noise, and they kept it today....they said they had never heard a noise like that before, but that it didn't sound serious....has anybody else had an issue like this? it is a e70, 3.0si, fully loaded....

does anybody have any ideas/tips/suggestions/questions I should speak to the dealership about?

thanks, and I know i'll post pics of the mineral green, as soon as the problem is fixed!
