HI
My 1.2 MK2b 2004 Punto temperature gauge has been playing up for a while now on long drive it will drop to zero for 30 seconds then goes back to normal , then goes again to zero again and the EML comes on with the fan, the next day it always goes to normal temp with the EMLgoing off.
Also have the temp gauge to over heating for say 30 seconds then go back to normal.
I have replaced the coolant sensor but it's still the same problem.
