Try going around the same turn several times at known speeds to induce the "nanny". Then once you can get it reliably to occur go VDC off. I bet your problem will be solved.

I believe this is caused by the unloaded rear wheel slipping as you turn. The throttle comes in to "plant the wheel and/or to negate your deceleration (moves your "traction circle" more toward the lateral axis as you turn.)

One note, that's a pretty aggressive (close to lateral g limit) turn to get the VDC to step in. Be careful out there. Cheers!
