   Hi,
   
   I have a problem with my Saxo 1.1 petrol, when driving temp light (red) turn on for 3 seconds and then the fan kick in and it turn off and than happens all the time.
   I changed green temperature sensor and changed it but it's still a same... i even bought diagnostic tool ELM327 but it cannot find any error on ecu.
   
   Can somebody knows whats the problem with it ? Thanks in advance !

   But blue one is for instrument table, am i right ? The green one sends information about temperature to ecu ?
   That happened to me once long ago, but mechanic only changed green one and it worked. But know it wont work even i changed the same as he did... Thanks anyway

   It's heat up normally like any other car... But it's not turning on fan until the red light shows up, then it turn on second speed on fan for several seconds and turns it off when the light dissapear...
   I read somewhere that this is the problem with relay on fan because it doesnt turn on first speed on radiator fan...
