All E90's 6-cylinder E90's use BMW's DSC90 unit/software.
The problem is that there are a few revisions to the actual hardware over the years. Each hardware change comes with a new revision #.
The software flashes are keyed to a corresponding hardware level.
If the two down't match, you get a hardware variant index error when trying to flash.
