Skoda Octavia 1Z Cluster Immo

[grga59]

Hello guys, i have Skoda Octavia 1Z, we changed engine inside the car now immo was on and we did immo off in ECU it was EDC16U1 and car starts everythings perfect but on Cluster says Immo active so i know i have to adapt immo in cluster but for that i need Login code so i know when you want to change mileage this cluster have NEC Processor and Eeprom so is it not enough just to read Eeprom to change mileage you have to read NEC and change there too but digiprog 3 do both i guess, but is it enough to just read eeprom to get Login code to adapt immo or i have to read flash too? Because i don't think i have any tool to read NEC procesor just eeprom.

Well, can't you read the immo data from the old (original) ECU?

Unfortunetly not, everythings dead and dropped. Now i just need to remove immo dtc from cluster. But i don't know if i can read Login code just from eeprom to adapt it with VCDS.

Does anyone know if I can read login code from eeprom?

Immo is stored encrypted in eeprom, so easiest solution is to use a proper tool which can read/write IMMO by OBD.
If you can do that then you can disable immo and the error should be gone.
You could even restore the ecu to immo-on again, insert that immo in cluster, adapt 1-2 transponders, and all will be as it should be!
