Is always your decision, but I'd strongly recommend that you apply a 12 month service schedule whilst the van is under VW warranty. It is so much easier to report issues and get them fixed whilst the van is with a vw van centre.
If anything has broken, become loose make sure that you report it when you take your van in for servicing. And always suggest that this should be fixed under warranty.
This is also the time when you discover whether your chosen vw van centre is working for you. If not, then find another....using feedback and recommendations on here
