Hello, I drove for example about 10 km (outside temperature approx. 20°) and then parked. Already the fan runs several minutes after. Then again only 3 to 4 km and already again the fan runs after shutting off the engine several minutes. What is this about? After such short rides the engine is not even at operating temperature. A few days ago still more than 600 km at a time without problems. Had an older passat (bj. 2007) with 2.0 TDi (140 hp). I never had this case. Greetings Michael
