XC90 T6 makes ticking noise during acceleration 1000-2000rpm
 

Hello
I have face up against a annoying problem when weather has been getting colder (-15). I can hear a ticking noise during acceleration between 1000-2000rpm. When I release the gas pedal the ticking noise disappear. I can't hear the ticking noise when I run the engine in "neutral" gear and rise the rpm. Please can somebody help me out with this issue. The noise isn't coming from the underlay as far as I understand (brakes or joints), because the noise stops immediately if I release the gas. When it's colder the ticking is ascending. Can anyone give me some hints regarding this issue.
