Nico,
If the level is fine, suspect the sensor. Or the wiring. Just because you 
replaced it once does not mean that the new one is not defective.

Have you recently bled/change the coolant?
This sounds exactly like the problem I had after blowing the radiator and 
getting a ton of air into the cooling system. Took a while to bleed all of 
it out. Keep adding the coolant.

There is a sensor at the bottom of the coolant reservoir (passenger side 
of the radiator shroud). It is not a floater, but as I never had to 
replace it, I do not know for sure how exactly it works.

Could be. Check the continuity.
Optionally, short circuit or open the washer fluid sensor. One of the two 
conditions will keep the warnings from popping up on the OBC.

hope this helps,
