I had mine done this weekend. My i made the entire 91 kilometers without needing a recharge in between. That was with light rain, two skyways and some uphill driving at 90 kmh / 55 mph most of the way and between 6 and 9 C. I had one bar left on arrival. After they opened the gates, I pulled in and started charging. I figure it would be a bit before they got to my car even though I had an appointment. But, after talking to the service writers they said it need at least several bars before they could get started anyway. I sat there for about six hours waiting for them to get to my car and for mine to be charged up all the way. I didn't quite get a full charge but left anyway, got tired of waiting. I quickly dropped the first bar and then lost the second one on a wrong turn. The third went pretty quickly getting back on the highway but for the first time I was glad to hit traffic. Instead of being over drawn, I was now in the positive. Got moving again and hit more traffic, decided to leave the highway and take the back roads. Made it home with two bars showing and 11 kmh remaining. Did actually better on the way back.
Did not notice any difference in the cars performance or behavior after the update. Still runs great!
