Just had this email from my dealer if it helps anyone. Ordered mine April 21..
'Again sorry for the delay in coming back to you. I did just try and call. I was waiting for an update from VW. We had a meeting today and they are running a production exercise from 27th-29th so I am hoping that this will provide me more info regarding your order.
The last time I checked it was estimating March, but at the moment, they are looking at things month on month, so our updates are very last min. I am hoping that once the production exercise has been completed I should be able to tell you more accurately if it’s still March or not.'
