Can anything be done ?

Consistently " auto-fill " shut's off way too early

Maybe post in the C6 forum for a better response....

Eh.. wrong forum but, hold the bottom of the handle/lever at "2 oclock" i.e., upside down cocked to the side. It will click off when actually full. Something to do with venting. Yes this means you have to stand there like a dick for the whole thing.

Considering it is a two seater, and the ladies love the car, I never have a problem quickly filling mine

Oh, you meant gas.

Most likely a plugged/kinked vapor line. The C7s are all prone to this especially at high speed/pressure pumps. My C6 stops exactly at full, no room to "top off" so I would think its a vapor line problem. Try running some Techron into the system but the only other thing is dropping the tanks and checking/replacing lines.

You have to stand there and hold it the whole time. PITA. But if you pickup(pullup) the gas pump handle instead of letting it lay down on the filler spout then it will run just about the entire time without clicking off a hundred times. Common issue on all the C6Zs

Mine shuts off prematurely every once in a while but not enough to pursue it. Definitely vent related but the upside down handle trick does usually solve it.
