Centre diff light flashes briefly when cornering?

[Supernova190188]

I have a 3rd gen surf 3.0td. I've noticed that when going a little quicker than usual , seems to be around a left hand corner that for a split second the centre diff light will flash , I tested it in a car park going left and right but no flashing light.
I take it this is nothing really to worry about? I thought it could possibly be to do with going around a corner too quick and the wheel trying to grip ? But when going in a quick big circle in the car park it doesn't come on.
