Hello and welcome!
As Snoopy said, both those items can fail on Mk6s. I had my PCV fail last year, but my car has considerably more mileage than yours (over 101K now).
Is yours DSG or manual? DSG gearboxes have a service interval of 40k miles which is worth remembering.
Intake manifold flap positions sensors can fail, and they are inbuilt to the manifold so needs the whole intake manifold changing if it does go, which mine has recently. This isn't something to look at preventatively as is obviously a big job and expensive part, just something to bear in mind.
Most of all just enjoy your new car
