Fabia 1.4 aub IAW4LV.C 036906034BK SKC/IMMO-OFF request

[A2 AUB BCB]

I have 3 BIN files.
The first: AUA (036 906 034 Q) IAW4LV.Z 95080
The last: AUB (036 906 034 BK) IAW4LV.C 95080 x2


I have found out that there might not be an IMMO-OFF for the 4LV.C (036 906 034 BK) ECUs.
Please do tell me if this is true.

Does anyone know the SKC/pin for these three ECUs?

AUA-A2-original - PIN 03550
AUB-SKODA-nr2 - PIN 07079
AUB-SKODA-nr3 - PIN 06308

[A2 AUB BCB]

PIN 03550 - works
PIN 06308 - does not work ("Login Code Not Accepted by Controller!") (also tried 42008 18A4 vs A418)

Try without 0, enter 6308, PINS are ok

[A2 AUB BCB]

PIN 6308 - does not work ("Login 6308 is Invalid! Login Code must be 5 numeric digits: 00000 - 65535")

[A2 AUB BCB]

Is it possible to change the 18A4 (PIN: 06308) to 0DDE (PIN: 03550)? With changing parity bits or checksum bits??



I have tried to program the ECU with 0DDE (PIN: 03550) instead of 18A4 (PIN: 06308) but then the VCDS says it is incorrectly coded.
I have also tried putting the ENTIRE bin from the AUA-A2-original EEPROM into the one of the AUB-SKODA ECU's, again says incorrectly coded.

Any other suggestions or recommendation would be great. I do apologize for the late response but i will keep trying everything.
