Loud sounds in the dome, switching and rolling on cobblestones

Hello municipality, some time ago I noticed that my Arona makes a rattling, rattling noise when switching from the first gear to the second gear. It is sometimes louder and sometimes quieter when you are domed. Also when switching into the third gear you can hear it, depending on the speed. But what causes me a headache, when I drive on cobblestone pavements, everything is OK with inserted gear. But now I noticed that if I hit the cobbler on cobblestones the clutch If I let go of the clutch and have no gear in it, the rattle will remain. Only with the passage in place is rest in the box :-(. The car has 4500km down since January and I can say that the Arona is driving quite reasonably. If I think that we want to go on holiday with the car, I somehow don’t have a good feeling about it. Tomorrow I will ask the dealer for an audience again, I’m curious what is being told to me. “That’s normal” I’m not going to get involved. Does anyone here have such a problem with their Arona? Greetings
