Hello,

I am trying to understand EEprom Structure of EDC16U1.
I already know the well know, Addresses for SKC, Milage, VIN, Immo-ID, Immo-Switch and some checksums

WE did some expriments with VCDS-ECU-IMMO-Adaptation to Dashboard with VCDS and monitored the EEPROM changes.

But there are a few Addresses in EEPROM whoch get changed by IMmo-Adaptation and I do not understand.

0x9D becomes switched from 0x02 to 0x03, ???
and in the Block, where is also the VIN something happens at
0x140 - 0x144 ???

0x40C also changed from 1 to 6 ???

It would be great, if somebody could explain me, what happens here.
