MSV80 change vin in Ecu

[rob h]

Hello guys,

I would like to change the vin in a MSV80 Bmw ecu.
I allready changed it in the Cas3 and cluster.

They talk about Winkfp. I dont have that, and not enough work in this Bmw platform cars.
So i figured, i could read bdm, using MMS. And manualy change vin in there.

Is there a otp area, in the ecu?
Checksum in ecu eeprom, might cause a problem.
Will a different vin, in ecu, cause dtcs?
I allready changed vin in Cas3 and cluster, will that cause dtc, in abs or airbag unit etc.
Never needed to do this.

This car 118i will recieve a upgraded 3.0i engine, with its own ecu, cas3 and cluster.

Any pointers how to this, would be great.

Thanks guys
