Default Whistle sound from engine

Hi! Anyone that can help me with this? Is my turbo about to give in?

I have a 2005 XC70 and can hear a low but clear whistling sound from the engine when I accelerate. I do not get this sound when the car is in neutral, and I need to put some load on the engine before it hits in (up-hill). The sound is there only at a certain rpm interval (around 1800 +/- 100) and more present when engine is cold, but also with warm engine at cold ambient temperatures (below zero).

Anyone with similar experience?

Hoping it is nothing to worry about...

Default RE: Whistle sound from engine

There are number of reason why engine whistles. It would be great to inspect all your car parts and check for a vacuum leak, cracked hoses, cracked intake hose etc. check also your intake manifold. After checking the parts, keep us posted and tell what other things did you notice.
