I believe you can do it, but I also believe VW will stonewall you all the way. The solution will most definitely be in the software, it will take a significant amount of hacking but the great thing about hackers is they are persistent...

/\ This. VW is notorious for stonewalling you on how to fix your own car. It's almost monopolistic.

Hello, do you have VCDS? I think it's necessary to overwrite the old fin number from the new battery.

I think you will need to also change out the charger, as the new cells are a different chemistry, and probably require different charging profile; or even different voltage?

Sorry for not updating.
There is not much progress really, and i do not have the resources or knowledge to make this happen all on my own.
If anyone is interested in buying the 35,8KWH battery (2017) i am offering it up for sale. Also i will be including the BMS from an 24 KWH (2015) battery.
Its located in Oslo/Norway.

Contact me on PM if interested.
