In my case I have to replace sme becouse some of transistors inside module was broke.I want have a calm head, because I don't trust regenerate parts which is responsible for battery. I think that cost of 1.8k$ isn't big investment in 100k$ car.
Actually you have to replace SME, code and programmed it and replace fuse in front of battery. That's enough in case of battery. Every service who make it now hate me
Sorry guys but I love share knowledge with others
PEACE
