Here you go:
MCUID = 4184028606A0020B
VIN = WVWZZZ3CZBE302118
CS = D377B4C84C1C
MAC = 00005F37
PC = 3A
PIN = 49318
State = Unlocked

I see part of MAC is 0000, so I think you already tried adapting by ODIS but failed?

[ruslan.v]

Yes, odis rejected this ECU. Now I see why... PC is wrong.

[ruslan.v]

Is it possible to change it ? Orginal car ECU was 03L906023DG. My test ecu is 03L906023FS. Both have the same HW. My idea was to programm immo and flash it to DG.

[H2Deetoo]

Aha that explains it indeed!

First you can change powerclass in target cluster (or prepare a temporary cluster with matching immo).
Once you have that, immo is valid, and you can cross-flash your ecu to 03L906023DG.
(And change powerclass back to orig value in cluster if you changed it.)

Most ecu's store powerclass in flash as well, so I would expect changing PC in pcr21 eeprom only is not sufficient.
I am not 100% sure about pcr21 though, maybe someone else can advise here?

Solved. Car starts.

I have to change ECU in this car one more time... will need CS and PIN form this dump.
