BMW i8 HV battery problems
Hi there guys, I have an i8 that suddenly started to develop HV energy system faults.After deleting all the errors in Ista+ i have the following ones
https://imgur.com/a/S5sJ7r4 I do't know what could cause this, though i did see some contactor stuck open in the faults before i deleted them.Attached those also https://imgur.com/a/91hroKe Anybody, ideas? I searched for TSBs that could account for this error, i found one but i can't get much information about it. TSB #B120917 Service Action : PROGRAM CONTROL UNITS.THE HV system is being shut off without a request from the driver. |

DC-DC converter fault in EME.
No charge for 12V Bordnetz. DC-DC converter can not change separate, only with EME. Used EME is problem too, in EME have EWS. Vanos Press Thanks and Reputation, if my post helped you. |

RE: BMW i8 HV battery problems
Looks like you need an EME. I have never tried a used one but they arent too expensive
