e-diff is the most absurd mislabel ever. It is brakes and power cuts. All E9xs have this, it's termed DSC/DTC. The post 03/08 version is programmed differently. The later version is not what I want because it is more invasive and apparently does not completely turn off some braking functions; IMO the pre 08 version works fine with all stages of DSC/DTC. Quaife or other LSD is great regardless of which version you have.
