I just received my 2019 M3 sr+ back from Tesla after a failing HV pack displayed BMS code a066 for a few days, then eventually stopped charging. With Teslogic I could see a 30%+ degradation and a large cell voltage min max. Displayed max range was below 180 miles.
The dealership agreed it needed a new battery and I drove the car for a week until it would no longer charge. Dealership said the battery was ordered. My wife brought the car in for me when it would no longer charge and they gave us a 2019 M3 Dual motor as loaner.
Car was out of my hands less than a week before it was ready to pick up. The first thing I checked was Teslogic and the battery is definitely not new and actually quite heavily degraded. Quite disappointing to see such wear after a service like that. Anyone have a different experience?
