1.4 TSI 2016 Starting in cold condition

Hi guys, unfortunately I find very little about my problem. If I find something it reflects the problem even in share again therefore I try to give here some very precise information about it. I know remote maintenance is always such a topic therefore I also have my car checked when changing wheels to find the problem. So I try to describe what happens. First of all the problem occurs only if the car has been standing longer (midday – morning next day). So ic h start the car normally, the speed is slightly increased, which is normal in the cold start, but it does not fluctuate or is uneasy exactly like the audible motor run is very even and in my ears. But when starting, whether back or in the 1st course it starts to jerk/bog so at some point between 9-12 km/h (observed). The speed remains when coupling in but over 1200 rpm as soon as I have then coupled it behaves to accelerate normally no noticeable ruckel n, of course I don’t give full gas in the cold condition but the normal acceleration goes without problems. If the engine is at operating temperature this problem no longer occurs. So only start at the cold start. I thought it was connected with the weather but this phenomenon does not occur every day. There were weeks there it was really bad, then again completely away and so on. I drive the car now for two years and only in this winter the problem has surfaced at some point t. In my memory after an emergency braking I had to do if that helps. The mileage of the car is 38 tkm and I am the first and only driver of the car, only V-Power 100 octan is fueled at always the same gas station (already crazy if I read it myself, well habit animal ) My driving profile is a lot of highway 30 km x2 a day (work back and forth). Then still leisure rides, but short distances I put back on foot my car is not made for 2 km. I h from already my own abilities doubted which makes little sense because my switching behavior does not change in the warm condition of the car. If something arises from the workshop I will of course update the topic for all who are interested or affected by it. Besides, you can live with the problem quite well because it occurs only 1-2 times and then is good for the first time.
