I just got my 2009 XF a couple weeks ago. It had a full tank, and I've just now needed to fill it. Last night I pulled into the gas station and could not get the fuel door to open. I pushed, I pulled, to no avail. I got my manual out and still couldn't figure it out. So I drove home. I have to leave the house in a couple of hours and am worried I won't be able to pump gas. I am hearing that this has been a recurring problem for many models. Can anyone help me? I don't want to break it but I need it to open.
