645ci (54) My car is sending me all these warnings one day then normal another.
the car told me that my battery was disconnected, i called RAC they jumped started it and said that the battery is fine and is charging also the alternator is good too. BMW told me that the computer of the car says to change the ECU then “IF” it dose not work then change the alternator and “IF” that don’t work Change the battery I think they are having a laugh KIWK fit gave me a print out that states 98% Good Battery And Charging at 14.48 which they said this is good. the battery has a green light on and seems fine, WHAT SHOULD I DO?
