To learn more about the e-diff, or eLSD, or ABD as it is variously called, this forum thread is a good place to start:

The original post contains most of the valuable information that the rest of the thread mulls over.
This write up does a good job encapsulating exactly what the e-diff is:

So, in conclusion, the ADB system is always active, however DSC and DTC can intrude and reduce its effect (cut throttle, apply brakes to realign the car or regain control, etc), but when all nannies are turned off with a 3 second press of the dtc/dsc button, it remains active and operates in the same manner as a mechanical limited slip differential, except it shifts torque via selective and progressive friction on the rear brakes (all brakes in a x-drive vehicle) rather than mechanical friction of gears in an LSD. |
So, I'm confused now?
Since my car March 2008 it doesn't have e-diff. Correct?
How do you explain 2009 or 2010 that would spin single wheel with DSC turned off?
If yes I assume my 62 years old mother in law took her 2010 e93 335i to have the e-diff coded off because that car for sure as hell would spin only one wheel too.
Just like mine 2008...
