Iveco Daily Bsi 503440080122 swap helo need!!

[razzyb]

I need help with some information
I programmed daily key. In process of removing and soldering back eeprom. I knocked off few SMD components held up in jig. I don’t know what they were resistors, capacitor, diode or else. I replaced off the shelf SMD component with matching color etc.
No start, cant communicate to BSI by OBD either. so I need to change BSI with second hand one.

Vehicle details, Iveco Daily 2010
BSI Magnet Marelli 503440080122
MCU NEC 70F3238M2GJA
Eeprom ST 9532W 95320

I think systems identify each other with VIN,
My question is will it be ok to just swap 8 pin eeprom (TSSOP-8)
Or I will have to swap MCU file as well.
Many suggestion, much appreciated

The eprom and processor is paired, so change together.
