I have a 2016 F10 BMW with mileage on the dash showing 999999 and a red dot beside. Once opened the dash I found a little EEPROM emulator (see photo attached). Does anyone know what is the original memory chip? And what are my options getting it back to normal?

Bosch part 0263726430
BMW part 6844031-01

you can put vvdi 35160 chip and write the id into it. read the chip welded on the emulator and try to read id. if you have the id just find a good dump from the same year model and the virgin the dash and code it after should work. most important to have the right id that will match the MCU.

Ok I have a blank 35160DW EEPROM ready for programming. Can someone please check the EEPROM that I have managed to read from the EMULATOR?

You don't have chip id in your eeprom dump.
Read eeprom from emulator as M95256.

I tried reading device serial number (Chip ID) but can only see all bytes FF.

So I removed EEPROM chip from the emulator and read it as 95256 chip, see the attachment.

Chip ID at 4000 in your eeprom and must write in new chip at 800
