Yes under some circumstances, ie if you have just come up a long hill or been towing, or when you pull in for fuel on the motorway. Skoda sensibly advises this in the car’s handbook. But normally when you complete a journey you are subject to speed limits and some slow driving, and that will be enough. The turbo on this engine is watercooled anyway. This gives the added benefit of warming the engine and the cabin up faster in winter. Diesel turbos are rarely watercooled.
