I recently bricked my DME for my 335 so i purchased a second hand CAS Module and matching DME from the same vehicle. I was wondering how to write my VINS onto those modules so it matches the rest of my car.

Not 100% certain, but I think you will need the matching key as well. To get a new VIN in those modules require replacing the chip and using the proper software to write data to those chips.

Cannot be done with 'user' software. You need to modify chip directly. You can invest in the tools and soldering skills or just contact someone like ecu doctor...
