The importance of the PCV valve in TSI engines

Original Poster

Hello friends, one of the reasons for oil consumption in TSI engines is said to be the PCV valve failing and staying open — I'd like you to share your knowledge and experience on this. For TSI engines after the 2013 model, it's said the PCV valve is the one next to the oil filler cap, but in my detailed research it's said the actual PCV valve is the part with code 04E103464AA located under the intake manifold — has anyone replaced this before?
