I've got the same problem on my 2000 S. The fuel gauge reads 3/4 after a fill up, sometimes goes up after a while, sometimes not. It seems to be accurate from 1/2 on down. Porsche has issued a Technical Service bulletin for this. It involves untangling some of the wires, hoses, and fuel gauge float in the fuel tank. It doesn't look to be too much trouble. I'll have a go at it Saturday and let you all know how it goes.
