Hi together,
trying actually to find out the SKC from my Audi TT 8N 2000'.

ECU is APX with 8L0906018M_0002
Cluster is 8N1920880H M73 D56

already read out ECU's EEPROM with ArgDub's tool and cluster EEPROM with VAG K+CAN Commander v2.5, please see attached.

But as it is a immo2 there is no immo data inside ECU "FF FF" --> 65535.
When looking inside cluster EEPROM, I looked at the 2 bytes in front of the Immo ID, that stated "1D C5" --> 07621, but this code doesn't work. Did I anything wrong here?

Thanks in advance
