ESG module not coded to my VIN?

[BladeX5]

Guys,

I've discovered (now that I have INPA) that my car's EGS module is not coded with the VIN of my car, but another one.

It seems it got tosted a long time ago and someone replaced it with another but it was not coded to my VIN.

So, 2 Questions here:

1) Is there any chance to code it to reflect the correct VIN and stuff? If yes, then how?
2) Are there any implications/issues about using it like that? I meant, is like that since... I don't know how long, but it has to be way way back in time since the last owner didn't know about it.

Thanks!
