On my downtown 300i , I have ran it dry a couple of times, ( I had a gas can on board) at 250 miles the last bar quit, and what was left is a gas pump showing and there was 6 miles to empty, when that happened, should be the same for the GTI, with the tank of gas is full, never park it if it is hot out, it will expand and flow out to the vent thingy ,. ( Im having a senor moment , )thingy HA HA,. wait till im 90, seven years to go,
