Yup, in the end it was over 20 hours of phonecalls, half dozen visits to the dealership, 3 hire cars over 3 weeks. Over 15 members of staff involved of which 8 were supposedly management, all because a sponge had broken off a plastic clip. If it was just replacing the clip I would have done it myself but the glass costs were over £1k so warranty claim it had to be. One of the issues was them breaking the glass after doing the repair and leaving all the broken glass inside the door, didn't bother to vacuum it out, then didn't bother to replace the vapour barrier before reattaching the door card. Scratches on the other door card where they'd used a tool to lever out more trim. Even when it went back for those repairs the master tech working on the car routed the central locking lines through the wrong holes on the replacement vapour barrier meaning they wouldn't have worked again, but fortunately this was corrected before handover.
What was really frustrating is I was adding silentcoat and other sound proofing materials to the car over the summer with some improved speakers and couldn't finish the work until Toyota signed off and completed the warranty work. Still got the 2nd batch of materials to cut and fit which will have to wait until spring now.
