Disable DTC P0340 on SAGEM S3000 Megane 1.6 16v
Hello mates,

Could anyone please help me disable DTC P0340 on a SAGEM S3000 ECU from a Renault Megane 1.6 16V?

Read details:
  • Tool: Kess3 (Boot mode)

  • Vehicle: Renault Megane

  • Engine: K4M T7 (1598cc / 83kW)

  • Date: 17/05/2004

  • References: 8200387138 | 21584288-2A | 4104646965 | 8200321263

I have attached the vehicle document, ECU photos, and the original EEPROM and MPC files.

Any help with this file would be greatly appreciated.

Thanks in advance!


Kind regards,

Hello ayllon308,

Thank you for providing the modified file, but unfortunately the DTC is still present and there has been no change in behavior.

Would anyone be able to assist or point me in the right direction? A map pack or a DAMOS  for this ECU for WїиоL54 would be extremely helpful, as I haven't been able to locate one anywhere.

Hello mate,

Thank you for your help and for sharing the file.

I have just tested it on the vehicle, but DTC P0340 is still present and reading exactly as before, as if no changes were applied.

Would it be possible to try a different approach or a new modification if you don't mind having another look? I am open to testing any new file.

Thanks again for your time and support!

Hello mate,

I have tested the latest file, but DTC P0340 is still present. Could we try another solution if you have any other ideas?

Thanks for your help!
