OK, so I'm lead to believe that the mk5 ibiza has a 45 litre tank, like my old Ibiza 1.4 used to.
So usually when I fill up I've done around 300 miles and the fuel light comes on at about 40 miles left. When I fill up with less than 30 miles left (sometimes closer to 10 miles left!) the pump clicks off with only about 40 litres filled so I think there's still fuel left in the tank (hence the range is better than my old 1.4)
However a couple of times, like the last time I filled up I had 288 miles on the clock with 30 miles on the fuel computer left, and the filler clicked off at 44.5 litres!! I can't have been that close to empty I'm sure??
I did notice that the pump was really slow and it took ages to fill. Once as an experiment I deliberately filled slowly having read somewhere that the pumps are more accurate as you get less vapour produced and the pump registered a similar amount for the fill (i.e. more than usual before the pump clicked off)..l.. so it does seem to be related to filling speed as I usually fill at max speed.
Does filling slowly end up with the same effect as venting the tank do you really manage to fill more fuel/less turns to vapour??
