When I first got my XF (Premium Diesel Luxury S - 2011 if this is relevant) I noticed that when I was filling up the fuel was "!Removed!" out underneath. I called out the Jag assistance people and they said it was a valve in the fuel tank that was supposed to close when filling up to create a vacuum (I think he said the last bit) but was staying open. He couldn't fix it at my house so I took it to a Lancaster dealer who replaced the valve. It was ok for a while, except that the pump kept stopping like when the tank is full up - except it wasn't full. The remedy short term was to slow the flow down so much that it is painfully slow to fill up. Now I noticed yesterday that fuel is "!Removed!" out when I fill up again. Of course I will be taking the car back to Jaguar again. I just wondered if anyone else has experienced this - dangerous - problem?
