Hi Hans Those are opposite symptoms - fuel gauge shorted to earth (intermittently), temp gauge open circuit. If there is a single cause a possibility (not uncommon) is that the wiring loom has been chafing on the steering column bracket. That's something that should be checked as a matter of urgency to nip any more serious problems in the bud. By the way, if you haven't done it before, removing the instrument cluster can seem quite daunting but it's actually quite easy. https://www.classicpartsshack.co.uk/store/p7/Ford_Fiesta_Mk1_Dashboard_voltage_regulator.___nos.html Best regards Bill

Is the fuel gauge still working ok ?If thats stopped working as well then it could be the voltage regulator on the back of the instrument cluster.
