Warning Buzzer On New Clocks

[DR SCHNITZEL]

I have just tried to swap out my old clocks with some new ones. I have noticed that the coolant warning buzzer comes on afetr 5 seconds and does not turn back off. I had a look around couldnt see any reason why it would. I have just swapped my old clocks back in and the buzzing has stopped. Im confused. How can i stop this buzzing on the new clocks:god

Sorry for the thread revival, did you ever trace the problem, just had exactly the same experience. My odometer wasnt working and had some replacement sets with the car, 2 infact. Both sets activate the cooling buzzer, old set back in, no problems?
