Default S40 1998 low voltage alternator at avereage temperature.

Hello.

I hope I could get some help. I got an 1998 S40 2.0. First of all I had the first problem with the alternator so I changed battery and alternator. But I still having the same problem. When I start the car at low temperature it's okay at idle 14V but when I left the car by 15 min or more at idle voltage go down till 12.5V - 12.7V. I take to many places and no one knows what is happening.

Anyone here have and idea?
