Notes on this file

How to identify your ECU
On the label
The Bosch label on the EDC16C34 housing shows the hardware number 0 281 012 523 and the PSA number 96 648 434 80; it may also carry a Bosch sticker number starting with 1039S. That 1039S number is not the software: the software 1037386170 only appears when you read the ECU with a tool, or in the INFOS.html of this archive.
What KESS / KTAG show
| Field | What the tool shows |
|---|---|
| HW | often empty – use the label |
| SW | 1037386170 |
| SW upg. (SW màj., soft up, UpgSW) | 1037393450 |
Look for the pair 1037386170 / 1037393450 on the identification screen (SW and SW upg., or SW màj., soft up, UpgSW). The pair, or 1037393450 alone, points to this file; 1037386170 twice points to the non-updated read.

Questions about this file
Is EDC16C34 0281012523 1037386170 1037393450 a full BDM backup or only the flash?
Full backup: the 2 MB external flash and the 95160 EEPROM were read together from the same ECU (Citroën C3 1.4 HDi application) – enough to restore a bricked unit, clone it or start a stage 1 on 1037386170.
My tool shows SW 1037386170 and SW upg. 1037393450 – is this the file?
Yes, exactly this one: the flash holds the updated software 1037393450, and 1037386170 is the base number the ECU still reports.
My tool shows only “SW upg. 1037393450” and nothing else. Same file?
Yes. Some KESS versions fill only the upgrade field on an EDC16C34. Confirm 0281012523 and 9664843480 on the label and you are good.
Does it fit the Peugeot 207 1.4 HDi?
Yes – the 207 is confirmed for this software. Check 0 281 012 523 and 96 648 434 80 on the label and software 1037386170 in your tool before ordering.
Will this file work on a Peugeot 206 1.4 HDi?
Only if the 206 label reads HW 0281012523 / PSA 9664843480 and the tool shows 1037386170 / 1037393450. It is reported with this software but we did not read it from a 206 ourselves.
