Regarding the PCV replacement, Ian's video is for an R36. I've done this job and it isn't too hard as the R36 has a two piece inlet manifold.
I got the sensors from Aliexpress but I found that for later model VW's, say 2010-12 onwards, generally the sensors were more readily available. So there were plenty of those on "the bay" from US, UK as well as China. The sensors for my car are (upstream) OEM 022906262AN and 022906262AM but my choices were either to fork out $420ea from VW, $250ea from one Oz site and at the extreme end about $80ea from China. Of course those prices were only for the parts and did not include the fitting.

For my car the European shops appear to have plenty of stock but they mainly deal in Bosch, FAE, Metzger, Vegaz, NGK. They also sell this brand Meat & Doria. I suspect though these Meat & Doria are same Chinese sensors which I could buy on Aliexpress the difference being I could get them directly from China at about 1/2 the price.

Regarding Ian's video - I did have a look but found that on my 2006 B6 3.2Lt engine the manifold bolts layout is different to R36. Also I think 3.2Lt engine manifold is not a 2 piece manifold. It looks like to take it off one needs to take the grill/bumper bar off? etc, etc. No wonder VW charges about $1400 for the job. I wish there was a video on 3.2 engine as PCV is the next thing I have to have a careful look at.
