i also paid for the service pack so will have to book it in soon,
When you had the service pack what info did they give you?
When I picked mine up they gave me a sheet with my detail on and conditions sheet. Talking to other VW users they had the official documents through the post but they say it can tack 4 months for this to arrive. 
I got the documents when i picked up the car,they also sent out duplicate documents about a month later for some reason,mine is due its first service as its just over a year old now but still low mileage,i will have to ring them and arrange to get it done when i have time.
