1996 VW Citi Golf Carberator type Chico 1.3. Heat gauge not working / working only sometimes for brief period. Also struggle to start when hot. I replaced the coil with the electric box , radiator (it was leaking slightly) , thermostat , brass type heat sensor switch , tested the fan sensor switch at bottom of radiator , engine now is running cool and fan switch on when needed. No starting issues - also checked all fuses - except the relays were not checked. Only thing is heat gauge still not working. Any suggestions or tips.
