I dont have driven with the manual box has i have the auto box in my plus four . I dont think it is a dual clutch auto box , audi and volkswagen made them but i am not sure for bmw.
After more than two years of ownership i have discovered a function of the auto box i dindt knew. When your are in sport mode the box change also the gear automatically altough i tought i had to use
the paddles at the wheel to go up or down . If you touch a paddle the box stay in the same gear but when you keep the right paddle 2 seconds it goes back in auto. The same between sport and sport plus.
In sport plus if you touch the paddle the box goes in sport mode . When you keep the right paddle on for two seconds the box goes back in sport plus. When the ground is wet or slippery i dont stay in D mode.
I you push too hard on the accelerator in D mode the box suddenly lower the gear when you dont expect it. And with the torque of 40 m/kg at 1200 tr/min the car dont keep his line. This can be dangerous if someone his coming in your direction.
