068 - Clutch Saftey Function, those numbers did not change either.
063 -Reset Values (Steering Wheel Paddle Installation); did not use.

Diagnose > Common System > 09 – Central Electronics > Adaptation > 006 > Change 0 to 1 > ENTER

fiddling around in other function areas. However, if you navigate straight to Central Electronics / Adaptation from plug-in, this should work.
