Battery died.....fuel gauge shows empty
Not a perfect answer but may be useful. This link isn't about Jags and I haven't had the experience but it seems to indicate it may just take some cycles of running and it is likely to go back to normal. Jac

Also, what does the RANGE computer indicate? Does it coincide with the improper gauge or with the actual fuel in the tank? Just me wondering...

When I first got my '07 XK, the estimate showed a 420 mile range for a full tank. Took a 400 mile drive, mostly highway, with no refill (but I was pretty nervous about making that last 50 home).
Since then, due to lots of local driving, the range estimate is much lower.

Thanks for the reply guys! Appreciate it. Lol yeah your right. So 300mi until empty is actually reading normal then correct?

Would Cee Jay's procedure reset it? And why is it necessary to touch the positive lead to the negative terminal (post) rather than just waiting five seconds before reconnecting it?

Touching the two leads together instantly drains all the volatile memory. Simply leaving it disconnected for a bit wouldn't discharge anything, and all the volatile memory would stay intact. Now, leaving it disconnected for a few DAYS would probably allow the systems to slowly discharge would probably work also, but why wait?

The windows will need a reset, but those are easy. The top SHOULD still be OK, but run a full cycle anyway to make sure. The stereo should still be OK, the seats should still be set, all the vehicle setting will still be OK....... everything that has a Memory Hold function should still be set.
So to answer your question.... other than the windows (and maybe top), everything you would want to stay will stay as it is. I guess some people lose settings, but I've never lost any (sans windows).

The fuel gauge in my '07 XK over-reads. The display seems to move in proportion as fuel is used up, but when it reaches half-full on the way down the tank is just about empty.

So, we know it's not that (thanks CeeJay). Does anybody know any other simple fix I might try, or should I just go to the dealer, drop my trousers and bend over...
