No i don't mean downshifting into first when you were previously moving, it will never do that unless you completely stop or go up an incline of more than 10% under 5 km/h.

No I meant when you are stopped at the lights on a hill facing down. Light goes green and you take your foot off the brake and the car starts to roll naturally. When you then accelerate it drops the clutch when engaging into first with a little bang (or not what you would call a smooth pickup). Have you experienced this?
