Evening all,
Just done the headgasket on the polo and the temperature warning light is flashing on the instrument panel.
I have checked the thermostat and it is opening up, so i assume the water is circulating.(new water pump has been installed)
The light has stopped flashing after a drive but it is erratic.
Does the light signify anything else? also is the light controlled by the sensor on the expansion tank?
thank you.
