There is a certain chemical compound in the coolant which can have a reaction with the parts in the car's coolant system. This is a rare case, but has been seen before where once the reaction occurs it causes it to overflow. This overflow was getting on the coil causing cylinder #3 to misfire. They are waiting on BMWNA to tell them what parts need to be replaced to resolve this issue.
lol - Hopefully they fix it fast and give you a nice loaner in the interim.
