If your car goes in for a full software update, it will definitely wipe your remap. This takes most of the day to load.

The issue here is how up to date you car is already.
If it is up to date, then the new integration level with the 'fix' will only be a small change to whatever module.
If your car is years out of date (like mine) then bringing it up to the latest integration level with the 'fix' will need to change a lot of other modules too as it brings them all up to date.
BMW techs don't choose which module to update, they just plug in and press 'update' and it does whatever it needs to.
So unless this 'fix' is being executed as a manual intervention by more experienced techs, outside of the general update process, then it seems to follow that your whole car will be brought up to date.
Unless someone has more detail???
