Hello everyone ,Bmw 118 D EDC17CP02 tried to read with Kess but the size of the document that worries me (1504 KB), I checked with WinOls are good, I do not know whether this size is normal or not?

its ok. you read in boot mode. i read with fgtech and same size.

read + remap + writte. all ok

not ok do it in boot tricore or car will not start. if you do it by OBD with Kess

That's right, car possible not start because will be problem with checksum.
Maybe good idea add "empy" space to end file as FF then all should be ok, but always is a risk.

Today I plan to read the Boot mode (Backup) and then to write by OBD. I think this will have no problem if in writing via OBD something unwanted happened?

No problem, anyway will be have backup :-) BMW ecu easy to get out
