Hello,

I am searching for an ori stock file for Bosch EDC16C2.

Based on the identifiers you've provided, here's what we're working with:

ECU Summary:

• ECU: Bosch EDC16C2 (EDC16C/C2-7)
• Bosch HW: 0281011624
• Mercedes HW: A6461538579
• Bosch SW: 1037390865 (P = programmed)
• Processor: MPC 555/556
• External Flash: AM29BL802 (AMD/Spansion)
• EEPROM: 4Kb
• EPEE: 1

This is a Mercedes CDI diesel application — likely a W211 / W203 / W209 era vehicle with an OM646 engine (2.2 CDI). Can you confirm the exact vehicle model, engine code, and year? That helps narrow down the correct calibration variant since the same HW number can carry different SW calibrations depending on the vehicle application.

A few important points regarding your request and attachment:

1. Your attached file edc16c2orgExtFl.rar (~246 KB) — this looks like it could be an external flash dump only. A full external flash read from the AM29BL802 on EDC16C2 is typically 512 KB. At ~246 KB compressed, the uncompressed size could be in the right ballpark. Can you confirm the uncompressed .bin size? It should be exactly 512 KB (524,288 bytes) for a complete external flash read.
   
2. How was this read? (BDM, boot mode, OBD?) — this matters for verifying if the dump is complete and correct.
   
3. The SW number 1037390865 is the key identifier to match an ori. Without being able to extract your RAR on this end, I cannot verify the file contents directly.

To help you properly:

If you're looking for a verified original/stock file to compare against your dump, you should:

• Confirm the exact uncompressed file size
• Provide the vehicle/engine/year
• Share the SW version string visible inside the dump (usually readable as ASCII near the end of the calibration area — look for a string like "CDI..." or a Mercedes part number starting with A646...)
• Confirm the read method used

If your goal is to verify whether your dump is original or already modified, comparing checksums (CS) and the calibration area against a known ori is the right approach. Post the details above and we can go from there.
