as mentioned, they exchanged both the OBCM and the CSM temporarily and it worked fine. So, in first place one would think they are broken.
But before replacing them, I want to explore my options.
Is there a chance that these components are not broken but only need some new software?
@all: If software won't help, where to get used or new OBMC and CSM?
PS: For the EDM, I found a thread, where some have replaced the internal Tyco relais by a stock one https://www.fiskerbuzz.com/forums/13...nt-charge.html
... which is by far the cheapest option...
