 This past December while lowering my soft top, I heard a rip. After raising the top, a small tear was noted. With Audi's inclusive warranty, I called Crown Eurocar (my dealer) and was given an appointment for 2 weeks.  When the car went in to Crown the service department rep said, "yea it is ripped and would need to be replaced (first day lost;they had refused to just look at it without appt.).  Returned 2 weeks later for repair.Loaner given and told it should take a day to repair. Next day the only tech who could repair it was out.  Finally it was determined that a defect was responsible, the car had slipped quality control and the entire top had to be replaced (after ok from Audi)
