On cold start it doesn't move until the car is warmed up, then you can clearly hear it open up. When I apply the throttle, it closes and opens up again. When I let go of the throttle at low speed it closes again, as soon as I apply the throttle it opens up again and then closes and opens up again.
Basically, as soon as I put my foot on the throttle, it opens up, as soon as I let go it closes again. I've only noticed this happening at low speed (5-10km/h).
This happens in Comfort, Sport and Sport+.
Does anyone else experience the same behavior?

Different model years and software integration have different valve behavior. For instance, new vehicles have that loud "cold start rumble"
every time you start the vehicle, even if it's already warmed up.
The older models only has the cold-start RPM hold
only when the engine senses that the motor is still cold.
Same concept goes with the overrun burbles between different software versions and variable behavior.
So it's difficult for anyone to pin-point if they're working as 'intended.'
