Question Audi A5 filling woes

Hi
I'm a total forum newbie but figure there are a load of like-minded folk on these things so time I joined.
Does anyone out there have any problem filling up their A5. On 2 out of 5 occasions I've filled my car up (first ever time and last time) the auto cut off wasn't triggered in time and fuel came gushing back out at huge pressure -and the stuff is too damn expensive for that to happen!!:zx11: Audi reckon there isn't a problem and I just need to go slow as it gets near full but I've never had a car do this in 20 years of motoring, and it's not always possible to know when you are nearing full if it isn't on fumes when you fill up. I also don't want to stand in the p'ing rain trickling it in for the last 10 litres....
Anyone else heard of this?
