write what active codes you have, what you used to read and what you will be using to write new file..

and tell us more about vehicle config..

in last posted file you have not dtc 2428 and 0546.. all ready deleted.
You must be running with some other file..

i overwrite that file
DPF OFF
EGR OFF
DTC OFF


vehicle travels a few km and those codes are activated again


I have compared reading with overwriting and I find no deviations.

try deleting dtcs first using diagnostic tool of some kind (opel or generic) with engine off, then rescan with engine off and if no codes write your file
