Diesel Leak

[Superoo]

Anyone else with a TDCi have an issue with diesel leaking out onto the ground if you try and fill the tank? Since new, I have never been able to fill the car up without at least a little spilling out. I've seen reports of this on the UK forums so I know mine is not an isolated issue but can't seem to get a straight answer as to the cause. It also doesn't appear to affect all cars. I've had the dealer check it 3 times and instruct me on the correct filling method which I find ridiculous (never had a car that needed a special fuel filling method to avoid it spilling out) but now it's just annoying. I don't fill it up to avoid the issue. It's obviously related to the capless refueling system and appears to be an overflow and not a leak as such but every time I try and fill it? I've tried everything but it seems ridiculous that I need to put up with it. Out of warranty early next year so I'm getting onto Ford CRC about this (should be fun after my last experience) but interested to know if anyone here has the same issue (and any possible solutions).
