Replace bcm Fiat Punto 188 '04

Hello everybody

I have a problem and hope somebody can help me.
I've bought a fiat punto 188 1,3 multijet with selespeed. My problem is that the body computer is broken in cause of water and burnt a little bit in one corner. I know that the normal way is buy a new one because it have to be coded by fiat.

Is it possible to get a used one and unsolder my old eeprom(s) and solder them to the other?

And if it's possible, which one should I change? And which body computer can y buy to replace?

Best regards

Sorry for my stupid english

move the eeprom and OK

I confirm myself. Last week the same problem. I solved it by moving the eprom.
