You're one of the lucky ones. It depends on your software version. Several members here (e90post) with LSD have reported non-intrusive e-diff activity, and they're often the ones who have avoided software updates from the dealership.

Traction control always fully disengaged. I can hear and feel the brake pulses by the e-diff when throttle is added during extreme slip angles and slides. It manifests as a rough vibration through the chassis and is quite loud at times.

DSC/ASC (DTC) detect and manage wheel spin. The E-diff just try's to keep both wheels spinning within 5% of each-other whether you have traction or not.

Double check in NCSDummy that the data value is 0 for the corresponding wert values you are using? You aren't the first person in the thread to speculate the e-diff is still intervening...
Good to know, 5% doesn't leave much room at all!

I really had high hopes the e-diff would stop intervening as brakthru reported. I used the same v41 DATEN files as he did... Anyway, I'll look at the data values and report back.
