Positive ending to a Flexible Fast Charger failure. Out of the blue - pun somewhat intended - mine suddenly displayed a solid orange line and an exclamation point. Dedicated circuit was fine, all had been installed by BMW recommended provider. Car had no issues. Took Fast Charges perfectly and quickly at Electrify America. I checked online advice, did trouble shooting, and took car to dealer service. Bottom line is that the Charger did fail and BMW replaced it. They have a rigid protocol that includes a client questionnaire and the service adviser did advise that it could take 3-5 days to resolve. But I was immediately given a loaner and was on my way. 4:30 the same day the car with a new replacement Flexible Fast Charger were ready for pickup. The paperwork that the service department had to complete for BMW was massive. But it was the detailed documentation that undoubtedly informs their engineering team. For me, it was a one pager that described the basic testing they did to confirm the fault. I have been extremely happy with my i4 and the dealership - Rusnak BMW - has been exceptional with every interaction.
