Our cars have a lot of torque because of the turbo. Try this, hold down the DTC button on the dash until the triangle with the arrow going in a circle shows up on the dash. Then jam the gas from a dead stop. No more lag, but you will spin the tires like crazy. Be careful.

I agree this could well be the software cutting the fuel, but I doubt this is because of traction control. This happens on very partial throttle (from 0 to 20%), and the behaviour (nothing happening and then suddenly a BIG surge of power) seem to be contrary to the principle of traction control.
And the traction control light doesn't show up on the dash.
I'll give it a try tonight with traction control disabled and see if that changes anything. But then I don't have the issue so often any more, so we'll see.
That been said, I strongly believe this has to do with software controlling the fuel delivery and the clutch actuation. Maybe if we all raise this issue with our dealer they could do something about it, if it's only software that should be a cheap easy fix for them.
