insignia coolant warning problem

[dave.t.]

I have a 2011 insignia, on starting the engine I have the LOW COOLANT LEVEL message on the screen, I have replaced both the reservoir, and the sensor inside it, tried disconnecting the battery for a while, but I still get the warning on the screen.
would be obliged of any assistance.
many thanks Dave.

hi there,
my problem is that my water level is fine, I am not losing water, after starting the car and resetting the warning via the stalk, it does not come back on until I shut off the engine, then restart the car.
many thanks for your suggestions. dave.
