For awareness for others, the information we have is that VW UK strictly enforce a maximum period of 14 days between arrival at the UK port of entry and registration and hand over to the customer. If not, the dealer must register it themselves, and run for a 6 month period.. We asked for ours to be delayed 3 weeks to get to the next registration year number, but it was a big NO in return. I believe the same is true for cars in the UK. From other posts, VW dealers in Europe don’t necessarily have the same handcuffs on them.
Glad it’s all worked for you though.
