Noise Cupra 290

I wish everyone a wonderful evening. First of all thank you for the recording! My name is Jasko, I am 19 years old and I am from Luxembourg. I realized my great wish 1 month ago and bought my Seat Leon SC Cupra 290! I am very happy with the car. But unfortunately this joy is slowed down by a small problem. When I start my car in the morning (i.e. cold start) a noise is heard 2-3 times after the overturning. the feeling that the sound is also temperature-dependent! I had brought the car to the workshop two weeks ago, but they assured me that every Seat Leon Cupra would make that sound. However, I didn’t want to be satisfied with it, because I still have friends who drive one and never had that sound before. I then contacted ‘Seat Luxembourg S.A.’. Suddenly my dealer called me and said that I should bring the car over again. The car has been standing at the dealer’s house for over a week now. In the beginning there was suspicion of a V-belt. This suspicion, however, has not been confirmed. My dealer called me this morning and told me that he reserved my rental car until 17 June. He just said that it would not be the V-belt. Unfortunately they do not know where to look for the mistake and have to contact Barcelona now. So now I wanted to ask if someone has the same sound before and if he could help me further I also put in a link, where you can watch the video! (If this is not allowed, you might like to point out to me! Here the link: http://sendvid.com/ar2s9eb2 Thank you already in advance!
