Had that but even worse on my first Leon on the piping down the edge of the seat where the seat belt would run over. When the BVA chap came to collect it the idiot wanted to charge £600 for it, I refused to sign his iPad. A chap rang me from VW who it was leased from and had looked at the photographs BVA had sent them, said it was clearly a manufacturing/design defect and they were not going to charge me. The current Leon has leather seats, no sign of any damage or wear.
