hello, i have read this ecu in boot mode, write the mod file and plug in car, the car does not start, so i write ori file back and the car start.
i tried to read by obd and read. i start the car and all work.
i tried after to write the mod file whitout checksum in boot mode, the write in boot mode was strange only one write, bfore made many short write and then one long write.
i plug the ecu in car, the car not start.
i take off ecu and try to read in boot mode.
cannot read in boot mode cannot connect.
i plugged in car and plug obd diagnostic it connect and read dtc, so communication work.
i tried to read by obd by galletto, cannot read by obd (while in first attemps i did a read by obd too).
otp areas damaged?
how to repair?

on all bmw do not chk with ols and than with tool . use everytime the tool for calc the checksumm and dissable the chk and sync in ols to mod the file ;-)
