My 2002 jaguar XJR has the coolant level showing as low even though it’s full. And the fuel gauge drops down to zero in between 3/4 and half a tank. So far after one estimate it sounds like it’s going to be $1300 to $1500 to fix both of them. I could get away without fixing them for a while, but after getting another estimate I might just get it out of the way. The Jaguar service place says the fuel gauge problem is common in the X308’s. The second place I got an estimate at said they would charge just under $700. That's quite a difference from $1300-$1500.
