Buttons of doors go down by themselves at low speed

Moin!Have brought my wife nen twingo! are so satisfied to the point with the doors!If you open the twingo with fb and get in everything is ok but as soon as you start then go down the buttons!That kind of bugs!Can you turn it off or change it somehow!more familiar of me drives passat and with that can adjust or so learn! does this also work with my twingo?The twingo is from 2002!And I noticed that if it is quite hot outside then squeaks the lentils kung (servo) but if it’s cold again then it’s gone again!Did anyone have that before???
