renault master 3 sid321 2023 - alex1971 - 06-12-2026
I need help, please!
Renault Master 3, SID321 ECU: when I turn on the ignition, relays start clicking after 10 seconds. There are 3 or 4 relays involved—one is under the glovebox, and the others are in the engine bay.
There are no error codes. When I start the car, it fires up but stalls after 10 seconds, then starts again... If I give it more gas, the engine doesn't have time to stall. It seems like the ground signal to the supply relay drops out for 1 second; then the relay engages, the engine runs for 5 seconds, the relay cuts out for 1 second, and this cycle repeats continuously. I suspect the ECU. I bought another identical flash chip for the SID321. I installed it in the car; the relays click on, and then—silence (no more clicking), but it won't start. Flex won't read the EEPROM.How do I read the EEPROM and change the VIN and IMMO data?
OR how to link a block? I don't think this is the only case. help me figure it out....
This is the original file; can anyone tell me where the immo data is located? (Willing to pay.)

Hi, I mixed up the file—sorry about that.
That’s not the point—the question is how to link the donor ECU.
The same thing happens on the original.

There’s no one to help. Are there no specialists for the Renault Master 4?
