Engine noise only on a cold morning DACIA DUSTER

Hi,

I hope someone does have the answer to this, my Duster is making a very strange sound on a cold morning just like the one in the video Link below,it does disappear after a minute or two but it’s not normal and I’m worried of not becoming something more serious,been to a dealership and couldn’t find the issue, 2 hours of manual labor and investigation cand be very expensive and can’t afford to go again and still the issue not being fixed, did anyone had the same issue and managed to fix it?
