    After MCU died completely, charging was limited to 21%. Independently if I am charging over UMC, CHAdeMO, or SUC (speed is full, almost 120kw at the begining) it charges to 21% and then report message "Charging complete" !
    No charge limit set to this point before ! I leave it at 80%, and after MCU gone blank I set it to 100% to secure myself if I loose connection over mobile app. After one day connection to car also gone, and charging become possible only to 21%.
    My black&white screen of mobile app show last data, and there is visible limiter pointer set at 100% for sure.

    Does anybody experienced something like that ?

    I dont see any technical reason for this situation, except some strange safety feature ?
    But then all people with bad MCU will experiance the same, and I cant find documented information about that.

    Answer from SC is that they will be able to see when they get new MCU ?!
    Im sure they can connect to BMS at least or something ?!

    One month without car, in Graz SC. No loaner. It will not be MCU2, MCU1 but with 4G internet. As I was told right now is 70 Teslas across Europe waiting for MCU replacement, because they ship it from USA in bulk, not one by one. As I dont knew how more long will be without car, I went to pick up a car, 200 km from home, and will use it at least with 21%.

    Thanks for any info & advice.
    I will update also when I see what will be in the end.
