Start stop display message problem

Hello to everyone. My car is 308 gti 2016 model. I came across something like this in my car. When driving on the normal road, the stop stop is activated at all times, there is no problem with it. However, at any time, especially on the long road, the eco mode functional eco mode functional eco mode functional message keeps sending to the information screen at 5 to 10 seconds intervals. If I turn off the start stop from the eco button, it does not give any warning. 2 different services were seen by izmir kahyaoglullari and izmir halil öztürk. They said it did not give any trouble code when connected to the pc. I bought a brand start-stop battery 2 months ago, 45 thousand maintenance was done completely new. But I could not get rid of this continuous message. I am open to any suggestions. Good day everyone

Hello, teacher. In order to switch to eco mode, there should be no electricity from the charger to the battery, and have the alternator checked. I say.

I am master. Looked at the 2 service Eco ya passing, he said no problem. Only on my home screen it says 1 eco functional at 2 pm. Otherwise, start stop is working properly. Connected to pc, they couldn't find anything

It can be like a software case. If you want, my teacher, I would like to reset and update ece and bsi.

I will ask and write the details, thank you very much
