I believe the temperature gauge is on the I_bus but not sure about the fuel gauge. I know the I-bus can be affected (amongst other things) by corrosion of electronic boxes in the boot. So is the boot dry?
If the Trip Screen Diagnostic shows that the temperature sensor is beeing 'seen' by the IPK, then the problem seems to be with the gauge circuit. eg the earth return as mentioned by bl52krz.
