Hello, Unfortunately I still have a problem with the V-belt. My MV6 regularly rips the V-belts. The new one also makes noises that had never heard before. At my Caravan X25XE the V-belt is torn this year in Italy (blatter crack, no tearing). It took me two days to get a new hotel, including a new belt. Tightening roll. There was only a short whistle to hear, then was quiet. The V-belt, which was not really on I did not find any reason for this change. I saved the video here:https://youtu.be/NRiHVfPsLA4 Maybe someone already had this or knows advice? Greetings Thorsten
