Steam/smoke from the exhaust also minutes after shutting off the engine

Hello together, the title of the topic already describes what it’s about. My Q2 (1.4 TFSI 150 hp, approx. 7000 km) steams/smoking from the exhaust after which the engine is out. The whole thing lasts quite a few minutes and I am not quite sure if this is normal. A picture is attached. Maybe someone can say something about it. Incidentally, the whole thing should not be related to the cold, because I have already observed this phenomenon when it was significantly warmer. Thank you.
