Citroen C4 Picasso - false error feedback on appropriate tyre pressure

[Blueberry]

Hi All,
I have a Citroen C4 Picasso 2012 and has problem with the tyre pressure sensor. Although the tyres are good and the pressure is correct, I receive warnings that the tyre pressure is too low or the tyre(s) is punctured. This error ended during the winter, but once the temperature is above 10 celsius the problem started again. The battery of the sensors are ok. I have just got the tyres changed to the summer ones, the problem still exists.

Has anyone faced this issue? Is there any solution for it? It is very annoying that during a drive it keeps changing between STOP and SERVICE with a loud beep.

Thanks for any help.
