Hi Fleur,
The only thing you really need to check is the actual build spec. That is the spec the factory have agreed to build. This can sometimes differ re options from what you have specced. It was in our case, re the aux heater option. Apparently the spec we ordered which went through the uk ordering system wasn't something the factory would build, so they just dropped the heater which of course for us was a deal breaker.
We also ordered in March but a couple of years ago and heard nada from the dealer until close to what we expected the build date to be. That's when the heater option c*ck up came to light. In 2014 there were a number of orders that were messed up by VW UK to do with the change over of model year which happens around that time. Miscommunication between the factory, VW UK, the dealers and the poor customers.
I would insist on a copy of the order in the system, it will take them half a day of offering you coffee etc. until you get it but make sure it is what you ordered, also check the order stage. I would have thought you would have a build date by now. And then as others have said, don't expect anything from the dealer until it is in their yard.
When they do the handover, they will be begging you to give them a high customer sat rating, obviously tell them you'll do the rating but don't imply it might be rotten. Then when you do the cust sat, be honest and detailed and then find yourself another dealer to do the services when needed. Although I'm guessing in Aberdeen you might have to make a little vacation out of each service to get it done somewhere else.
In our case, we couldnt fault the dealer. In the end we had a replacement van for a few months at no charge until our real order could be built. We joined the back of the queue. Since then, seeing as we're on a 2 year and 20k service routine, we haven't seen the dealer. And actually the sales side and service side of each dealership can be very different, you can get shoddy sales but great service and vice versa.
Good luck and enjoy the van when you finally take delivery.
