    clear IKE: BF [191] error with BMW scanner

    I have passed the BMW scanner to the car and activated some functions, but after activating them it gives me the following error in red in the IKE module: BF [191] Internal fault EPROM checksum 1 (BMW-section), incorrect / incomplete coding
    To try to remove the error, I have given recalculate eeprom checsum and it gives me the following message: No EEPROM checksum calculation for this IKE.
    Could someone tell me what steps I would have to do to be able to remove the error?

    There may be better ways to do this, but I would return coding to stock with NCSExpert and then attempt to make the changes with NCSExpert only.

    - E36 328is ~210-220whp: Lots of Mods. RomRaider self-tune work in progress.
    - 2000 Z3: Many Mods.
    - 2003 VW Jetta TDI Manual 47-50mpg: Many Mods ~300ft/lbs tq, diesel, daily beater. Love/Hate relationship.
    - S52 Estoril M Coupe
    - 2014 328d Wagon, self-tuned, 260hp/420ft-lbs
