and i have another ecu from Seat XL Altea 2014 same hardware 03L906023KL hw43.
is posible to swap immo one to another or somebody can make it if i provide the both eeprom dumps?
Engine is the same CAYC 1.6
Car even start 1 second and die do the immo.
Im not sure but ori eeprom file can be with checksum error, mabe thats the oem ecu problem.

Or, if you don't have tools to read full flash, uinlock eeprom from new ecu, reflash with FRF to match old one, re-read eeprom and post.

Flash read with Kess is not enought (are only maps).
Write this is Seat ecu and see if your tool see ecu unlocked.
