2014 P85D, 110K miles, warranty expired in January, and the SC recommended HV battery replacement after I went in for a few minor fixes. The issue was the morning of the SC visit. When I got in to drive the car there, I got my first error codes "BMS_w017 & BMS_f017... Schedule Service..." so weird this occurred the same day I was scheduled to bring the car in for a DU inspection for noise and other minor repairs and adjustments. Supercharging is slow, around 40-50kw at 50% SOC and 15-20kw at 75% SOC. I get about 180-200mi on 100% charge.
