Sorry ovekvam - I stand corrected, You are right: eLSD (eDiff) will only come into play when DSC is OFF indeed, so it should be seen not as another electronic "nanny", but a replacement to a "real" LSD in e.g. track drifting where the driver can safely switch off DSC.

However, am still not quite comfortable with the above statement - doesn't LSD actually *need* some wheelspin (actually, a difference in left/right wheel spins) to activate? And if so - assuming I'm still protecting my stability with DSC on - will the amount of wheel spin that DTC allows suffice for LSD working efficiently *before* DSC kicks in, cutting power and applying brakes to any of the 4 wheels (not just the rear) it feels necessary to prevent stability loss?

I guess that - after correcting my idea how it actually works with your input - the above is now my question (reworded, but basically the same: will LSD be used efficiently in DSC ON driving scenario)?

TIA!
