XC90 Problem

[Darlo74]

I recently bought an XC90 and there is an annoying whistle that starts when the car reaches about 70mph coming from the front passenger side of the car. It's not a mechanical issue, it sounds like air rushing through a gap which is what I'm sure it is. Has anyone experienced the same as the dealer is having trouble locating the problem and fixing it?

try folding in the mirror to see if it goes,think theres a mod for the casing if this is at fault,ie putting felt tape somewhere in the casing.

It might be coming from the roof bars.

Problem solved by a very persistent Volvo dealer - a seal from the heating unit that takes air in from outside was loose causing the annoying whistling. Took a good 6 weeks and 3 trips to the dealer to finally get to the problem!

Thanks for your suggestions
