I didn't get a book with mine that was delivered 2 weeks ago. Think it's a MY18 thing.
On one hand it's a good idea, means it can't get lost or tampered with. On the other hand the cynic in me thinks it's more of a ploy to make people use main dealers for servicing.
If independent garages can access or update the service record then it's not a problem. But if they can't, the only way to keep a service record is to keep all invoices etc. (Unless you get a book off eBay!)
