Hello everyone, with my Golf IV, TDI, 85 Kw, Bj 2000, 140 TKm last Monday the bolt is broken, which fastened the tensioning roller of the tooth strap. Thus the motor is over. I kept to all changing intervals. The current tooth strap was just 20 TKm or 7 months old. My question is now the following: According to the workshop bill also the tensioning roller was changed next to the tooth strap. Would not therefore also the fixing bolt have to be changed? What about a warranty claim? Greeting, Hajo
