Short “district” at motorway exits

Hello to everyone. After a long consideration, I also bought a V10 on 13.10.. Great car, so far no problems, as long as you can say this for the short time or about 6000 km. For a few days, however, I have noticed a short “screwing” when accelerating, e.g. when driving on a motorway or at the beginning of a fast-tracking process. It is really very short, not too loud, sometimes well audible, sometimes hardly perceptible, but it is not always! So far, it is not always easy for me. Is it possible to produce this sound on purpose. From the feeling I would say that it occurs while switching down. In my opinion, however, it comes from the direction of the right rear wheel. Can someone tell me what this could be before I run for warranty? Hendrik
