    i would say either the water temp sensor or the rad fan switch but most likely the first does the fan kick in

    If you get any error codes, check them here: Category:Fault Codes - Ross-Tech Wiki


    17704/P1296/004758 - Error in Mapped Cooling System



    Possible Symptoms


    • Cold start issues

    Possible Causes


    • Coolant Temperature Sensor (G62) faulty
    • Coolant Thermostat faulty

    Possible Solutions


    • Check Coolant Temperature Sensor (G62)
    • Check Coolant Thermostat
    Special Notes


    • Check the stored Freeze Frame data with this fault code. Freeze Frame information will be found in the fault code description (if the module supports it) or in Generic OBD-II if the vehicle complies with those regulations.
      • Freeze Frame data stored at -40*C is generally an indication of a faulty ECT or wiring.
      • Freeze Frame data stored at +140*C is generally an indication of a faulty ECT or wiring.
      • Freeze Frame data stored with in the 68*C ~ 80*C range is an indication that the vehicle was close to, but not within, the cooling systems normal operation range. The Thermostat itself or Cooling system components may be at fault.
