306 GTI Charging Fault Fault

Hello, good evening to all of you,

I have a problem with my 306 GTI vehicle;
My car stopped while driving on the road last year. I couldn't restart it as if the battery was over. I pulled it to a suitable place that night, the next day the master came in the master's brain, charged and went to the service. He repaired the charger and changed his miles. He said that I had to replace the battery.

After a few months, I changed the battery, time passed, I stopped at the red light on the way to the house, the battery light came on. the right fog lamp (xenon) flickered and extinguished. When it accelerates on the road, after 3000 cycles, the battery light turns off. era thought is burning again.
this time I took it to another master in the gardening industry and left the vehicle. it does the same thing when i receive it. When it is overturned, the battery light goes out, it lights up when the light stops.
I took it to another master, he said he did not charge enough. he said let's see. now I can't get a clear answer from anyone. can you help me?

I think the problem will be solved if I get zero of charge dynamo.

By the way, I have two amps in my car, when I first experienced this problem, there was only one amp. I suppose the sound system doesn't work that much, right?

battery: varta 60 ah 490cca -12V

thanks in advance
