Question what does the 95040 ME7.5 immo file for a 06A906032HJ ECU store to be able to match to a cluster.

To my understanding it stores the
VIN
SKC
Immo id
The reason for asking this question I need to match an ecu to a cluster ,   but don’t have the physical cluster and key to do this with me, only a dump of it.   I therefore want to amend the immo file for the ecu, for the correct vin and skc and what else  would I need to amend  to match the ecu?

Thank you
