Both memories were read from the same box, so they match each other (including the donor’s immobiliser data). The MPC internal flash is not part of the archive: it is not needed to restore, clone or compare an EDC15C2 with the usual tools.

How to identify your ECU
On the label
On the Bosch label of the EDC15C2 you will read 0 281 011 521 (hardware) and 96 563 143 80 (PSA), often with a Bosch sticker number beginning 1039S. The sticker number is a production reference, not the software: only a tool read, or the INFOS.html in this archive, gives the 1037… numbers.
What KESS / KTAG show
| Field | What the tool shows |
|---|---|
| HW | often empty – use the label |
| SW | 1037371515 |
| SW upg. (SW màj., soft up, UpgSW) | empty, or 1037371515 again |
Expected ID screen: SW 1037371515, upgrade field empty or identical. Anything else in the upgrade field → not this file, search the upgrade number instead.

Questions about this file
Is EDC15C2 0281011521 1037371515 a full BDM backup or only the flash?
Full backup: the 512 KB external flash and the 95080 EEPROM were read together from the same ECU (Citroën Xsara Picasso 2.0 HDi application) – enough to restore a bricked unit, clone it or start a stage 1 on 1037371515.
My tool shows SW 1037371515 but the HW field is empty. Right file?
Yes, KESS and KTAG often leave HW blank. Check 0 281 011 521 and 96 563 143 80 on the label; if the upgrade line is empty or repeats 1037371515, this is your file.
Will this file work on a Citroën Xsara?
Only if the Xsara label reads HW 0281011521 / PSA 9656314380 and the tool shows 1037371515. It is reported with this software but we did not read it from a Xsara ourselves.
Same hardware 0281011521 but my tool shows SW 1037369504?
Then you need the other file for this hardware: SW 1037369504 with PSA 9651593480, sold on its own page. 0281011521 alone is not enough to choose.
Does the EEPROM contain the immobiliser of the donor Xsara Picasso?
Yes, as read. This is the original state of ECU 0281011521, not a virgin file: for another car, transfer your own immobiliser data or use a virgin EEPROM.
