Can anyone one help P1531

[rtuk]

So I have this code up booked in to my local VW garage and they refused to diagnose my problem as the car is mapped! have been looking online and code relates to the N205 valve is this a replaceable part as I can find a part number anywhere or is it part of the whole cam chain tensioner assembly.

Car runs fine btw no running lumpy or misfireing, any help whould be appreciated.
