Build week confirmed now told to wait as VW are emailing all with orders

[Matt SB]

Ordered a replacement (some time ago) for my T6 California to upgrade to a T6.1 I have a build date confirmed as week 48, We’ve been informed by the dealer that VW will email everyone who has a new build ordered and then to get back in touch with the dealer. This sounds ominous! Has anyone had the email from VW? If so what does it say? Thanks!
