    Default 2016 citroen c4 picasso

    Hi guys, I have a Citroen C4 Picasso here, that has come from an accident repairer & has the codes-

    B120a: collision risk alert function fault: detection of impact
    B121D: BSI internal fault for adapted cruise: receipt of the impact information impossible.

    I assume these are crash data stored? I havent removed the BSI yet, but the part number is 980 6687980 according to my diag data. I am wanting to know if I can just re write the eeprom to erase these codes & if so, does anyone have a file?

    First of all , did you replaced damaged parts? Did you tried to remove DTC using Diagbox or Lexia ?
    It looks like crash data stored..
