If you don't ask, you wont get.
VW only stipulate that new cars must have 15 litres in. These days, that barely takes the light off.
It is entirely upto the dealer how much fuel they put in. At my dealership, we sell 750 cars every year. On an average tank of say 50 litres thats over 40,000 litres of fuel per year at say 90p per litre, it's about 35 grand. This is why we don't fill up every car.
If you want a full tank, tell the dealer that you want a full tank. Make sure you tell them before you pick it up though. Just remember that everything a dealer gives away still costs something. Just because it's fuel, it still isn't free to them. Most dealers won't fill up just because you are buying a new car. At my dealership, we always fill up cars from repeat customers as a thank you but that really is the exception.
As always, be polite and nice to the dealer and politely tell the salesman that you'd appreciate a full tank and he'll probably do it.
