This is normal for VW DSG. I have had various different cars now, Passats, Touregs and this is our 2nd Cali. All do it. If you put your foot down hard from standing still, the computer is making a whole bunch of calculations and is therefore a split second behind you. Hence the “dead spot”. Then it does exactly what you’ve told it to i.e. max power to the wheels. Hence the sudden jerk away or wheelspin. Although the computer learns your style, it will always put max power through if that’s what you’re telling. You should also adapt by depressing the accelerator a little until you feel the drivetrain engage. Then if you fully depress, it will still give you the max acceleration without the jerk. It doesn’t take long to get used to it.
