I have the temperature light staying on in my peugeot 106. I have changed the thermostate, both sensors, checked all wiring, checked coolant level, bled radiator, had a diagnostic test and checked all fuses. But annoyingly the light is still on!!! The fan is also on constantly.
Can anyone help?? does anyone know if I need to reset something or can you tell me which fuse goes to the dash light.

The fan will be running because of the radiatior temperature. Check that you have the right amout of coolant and also the right type of coolant as both these factors can mess up the sensors. It also could be a leak on the radiator, common with a 106
