Hello.
I have the following error messages on my 2013 P85.
This happened while driving.. Car cut off HV and soon after the 12V was dead as well.
First message was:
BMS_f139_SW_DC_Link_V_Irrational
Then::
BMS_w080_SW_Int_HV_Disconnect
There seems to be NO messages regarding isolation errors, internal or external so that's good I guess.
My personal diagnostic is the HV fuse but since I have to drop the battery to check it I turn to this forum for confirmation.
Am I correct in my diagnostic, or could it be something else?
I DID check all the cells with ScanMyTesla and they are all perfectly balanced, 0,005Vcd.
I am keeping it alive now with external 12V charger.
Car is still showing 70% in the app and BMS is showing nominal values like Max Discharge 201KW (battery is 0,3`C)
