I have not heard anything from a bmw rep would not believe them. I have read about batteries need to be introduced to the car. Have seen in my cars service records how prior owner installed an aftermarket battery seeking to avoid a $450 bil but didn't introduce it. He did not know to do that or have the means to do that. Then months later his transmission will not go out of park or worse. He takes to bmw service and they charge $100 for diagnosing the transmission and report finding nothing wrong with it. They report the problem is a incorrect aftermarket battery and then install another bmw battery. Total cost about $600.

So I was warning him, I am saying you either pay the money to bmw or you must buy a correct battery and also have the right software to introduce it.
