Hello, connoisseur and expert, I have a natural gas Arona 1 1/2 year old demonstrator, 700 km. Do I quite agree that the start-stop facility only intervenes when the oil temperature has a certain minimum value? It seems to me that it starts irregularly. Even at 81°C oil temperature it was still switched off recently. There is something lazy or? What do you do? Thank you for your advice ! Helmut
