What you get (2 ZIPs, 844 KB in total)
✔ EDC15C2 0281011521 1037371028 full BDM backup – external flash 512 KB + EEPROM 95080 (1 KB), read from the same ECU
✔ INFOS.html datasheet in 12 languages
✔ Unmodified original read – no tuning, no immobilizer change, no checksum work
Complete bench read of the Bosch EDC15C2 used in the Citroën Xsara Picasso 2.0 HDi: external flash 512 KB + EEPROM 95080 (1 KB) from one and the same ECU, delivered as 2 ZIPs with an INFOS.html datasheet.
A true full BDM, not a flash-only OBD read. Also, the download opens as soon as the payment is confirmed.
Two independent reads of the same software, from two different ECUs. Each read is complete and unmodified. Read #1 is the one to write; keep the other to compare or to double-check your own read – the differences are listed under Archive contents.

Two Xsara Picasso with the same engine can carry different software, so match the numbers on the ECU label – HW 0281011521, PSA 9654693280 – and the software 1037371028 shown by your tool before ordering.

Read #2 compared with read #1: 4 bytes differ in the flash (2 areas: 0x07EC12–0x07EC13, 0x07EC3A–0x07EC3B); 248 bytes differ in the EEPROM (35 areas: 0x000000–0x000004, 0x000007–0x000009, 0x00000B–0x00000C, …).
Because flash and EEPROM come from one ECU, writing both restores a coherent unit (donor immobiliser data included). 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.

Notes on this file
We read two EDC15C2 ECUs running software 1037371028 for this page. Hardware 0281011521 is known with 3 software versions in our catalogue; this page is 1037371028. Engine: Citroën Xsara Picasso 2.0 HDi (90 hp, engine code RHY).
Compatible with KTAG, KESS3, Flex, Autotuner, bFlash, PCMflash, BDM100 and similar tools. However, in rare cases expect a quick alignment in a hex editor or WinOLS before you write the EDC15C2. For professional use – workshops and ECU technicians.
How to identify your ECU
On the label
Two numbers on the label matter: 0 281 011 521 and 96 546 932 80. The 1039S… sticker is not a software number – 1037371028 is only visible through a tool or in INFOS.html.
What KESS / KTAG show
| Field | What the tool shows |
|---|---|
| HW | often empty – use the label |
| SW | 1037371028 |
| SW upg. (SW màj., soft up, UpgSW) | empty, or 1037371028 again |
Expected ID screen: SW 1037371028, 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 1037371028 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 1037371028.
My tool shows SW 1037371028 but the HW field is empty. Right file?
Yes, KESS and KTAG often leave HW blank. Check 0 281 011 521 and 96 546 932 80 on the label; if the upgrade line is empty or repeats 1037371028, this is your file.
Will this file work on a Citroën C4?
Only if the C4 label reads HW 0281011521 / PSA 9654693280 and the tool shows 1037371028. It is reported with this software but we did not read it from a C4 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.
Why are there 2 downloads for one software?
We read 2 ECUs running 1037371028. Write read #1; the other differ by VIN, immobiliser and adaptation data in the EEPROM, useful to compare with your own read.
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.
