I placed an order on 30th March, Order confirmation came through on 10th April with anticipated delivery of 17th August (Week 34).
13th April the dealer confirmed provisionally Week 21 with delivery 4 Weeks later.
VW tracker moved today to Build Week Confirmed which ties in with BW21 so looks like Week 34 was the worst case scenario advised on the initial order form.
I think it's a common issue and anyone on here will tell you the same thing.
There's numerous threads on this topic and it seems there's various reasons for it. Dealerships exceeding order allowances, spec of your car etc.
I'd advise ringing your dealer and asking for your unique order number, then you can spend hours watching the VW Tracker like I and many others do!
Out of interest, what have you ordered?
