Hi,

For the Opel Vivaro EDC16C36, a pure software immo off is usually not reliable without an emulator.
The best solution is to make the ECU Virgin and then adapt it to the vehicle using diagnostic tools (like OP-COM, Tech2, or Renault Clip).

Please read the EEPROM (usually 95320) from your donor ECU and upload the dump here. We can then help you prepare a virgin file.

Hi, i new user in this forum, but 20 years in car programations.
I can do Immo Off in Renault/Opel EDC16C36 units in full MCU file. For this moment not in all software versions, but in this version is avalable.
File is comercial, and if interest, welkome in PM.
I attach Immo off file, need make checksum correction.
Regards.

Good to know you can do immo off on the full MCU for EDC16C36. A few important notes for anyone picking up this file:

• The attached .bin is labeled "Immo Off no CS" — checksums are not corrected. Flashing without checksum correction will likely cause a MIL light or the ECU may reject the flash altogether. Use WinOLS or a dedicated EDC16 checksum tool before writing.
• File size is 2.00 MB — consistent with a full MPC5xx MCU dump for EDC16C36, that checks out.
• Always verify the SW number inside the modified file matches the target ECU exactly. The original post references Bosch HW 0281017065 / SW 1037503114.

@noslen — if you use this file:

1. Confirm the SW version in the file matches yours (1037503114).
2. Correct checksums before flashing.
3. Flash via BDM (boot mode), since MCU-level immo changes typically require it.

If it doesn't work out, the proven fallback is still making the 95320 EEPROM virgin and re-adapting the ECU to the car with OP-COM or Clip.
