Brought the new X5 in for service on Tuesday to fix an inoperative passenger seat heater. Figure this would be a simple thing of swapping out a module or switch. So far it’s been in for two days and the dealer has been back and forth with BMW Engineering with no progress as of yet. According to service advisor he says it’s loosing it’s signal somewhere between the switch and the seat. They are going to call me again tomorrow with an update but cannot give me any ETA for the repair. Anyone experience this?
