Hello!

I wonder if it is possible to force ASD to work from standing still. I mean I have a 300TE and I had a pretty bad experience in winter, when I tried to turn around and got stuck in a track in slightly iced snow. Swithing from D to R and back made no sense, because ASD doesn't block when the car stands still.
It works from 10 km/h I think. It blocks so good, so I can lay some significant amount of rubber doing donuts when it rains. It blocks on dry road at WOT aswell.
Is that possible to wire a somekind of a switch to force ASD to block to avoid such situations?
Or my ASD doesn't work properly? When I start at WOT with the front wheels turned it usually blocks, but it doesn't block on slippy surfaces.

Thank you!
Alex.
