not worth the risk, I did that in my old Honda when fuel light went on, drove 30 more miles, because I was driving from New York to DC, it ran out of gas about 2 miles from home so I had to push the car to nearest gas station for good 15 minutes.
it all depends.... I regularly play diesel roulette. but I would only chance it if you are changing your style of driving and road types. ie. If you've been bombing around country roads all day and the range says 20 miles, you'll probably get 40-50 on the motorway. but if it is similar driving you wont get 26 miles out of your tank. this is why the car has an Eco setting
I've managed several miles on zero range, and it appeared to have a litre left in the car when I filled up.
i've gotten to 20?, or so miles past 0 on my mk6 gti.
i do not recommend this for many reasons. i have heard that besides the obvious common-sense stuff, that it's also not good for the engine to run-out of gas? not sure if that part is true. maybe somebody who knows more could comment on that. the mk7 gas tank is smaller right? also, not sure if that has a effect on what you might get.
i'm curious too how far you go though, if you try it.
It's not good to let the fuel tank run that low - the fuel pump relies on gas to keep it cool. I didn't know that but I burned out two pumps on my VW Fox and the mechanic told me that frequently 'running on fumes' does have an effect.
I just filled up after car said 5 miles to empty, I could only manage to fit 43 litres of fuel in, so theoretically there should still of been 7 litres left in the tank, enough for about 50 miles I think
