V8DerKracht

Hello, good day, my question relates to a W222 from the beginning of 2017 because I bought this car new. I am now fixing the problems of the previous owner's car. The seatbelt roller on the rear right no longer rolls up at all, even rolling it up manually doesn't work Maybe someone has already had experience with this or knows what could be the case. I would like to thank everyone in advance for all the answers and efforts. Best regards
