Blue coolant light

not my Clio but new shape trafic. It’s back in dealer for its list of monthly warranty work .
One of which is coolant light sometimes flashes or goes off as normal then flicks back on and goes off again.
As far as aware the light just tells you it’s warmed up?

Hi Steve. I’ve noticed on my 220 the blue light comes on from cold and then goes off once it’s up to temp. Doesn’t come back unless the car has cooled down for long enough.

Hi, that’s what mine has always done but a couple of times it’s flashed then gone off.i don’t think it’s a level sensor so wondered if it did anything else.

Sounds like typical French electronics to me if I’m being honest!
