Fuel Gauge problem

Fuel Gauge problem
About a week ago I was about to drive to Manchester from Bristol. I checked the fuel gauge and it read just under half a tank. I thought it was strange as I was sure that I hadn't used the car much since I last filled it up. I went to the filling station and I could only put in about £20 worth of fuel before the pump shut off. When I checked the gauge it was now saying full. I did the trip and when I got back to Bristol I again filled the car up. Everything seemed ok so thought it was just a blip. I drove home with a gauge that said full (about 2-3 miles.) I came to use the car again the next day and the gauge read the same as when I was going up to Manchester (just under half a tank). Every time I have used the car since it has read the same.
Anyone got any ideas or experienced the same problem?

Welcome to the forum Concorde Ken,
Your XF, like my XK, has a "saddle" tank. There are a few variations depending on specification but this diagram shows the general layout.
There are two level sensors and a transfer pump to maintain an even distribution of fuel. I think one of the sensors and possibly the transfer pump could have failed leading to the incorrect reading.

The same thing happened to me when I had an '06 S-Type. Gas gauge was all over the place doing what yours is doing.
Luckily, it was under an extended warranty and cost nothing. Dealer service manager said it would have been $800 + - to fix it.
If you can remove the rear seat and find out which pump, you may be able to do it yourself and save a bundle. That is if the pumps can be accessed from the rear seat area.
Good luck.
