Today I replaced my voltage regulator and the issue is fixed. I did it while the car was on the air but you can also do it if you jack the car up on the street.
First remove the negative terminal then 3 13mm nuts after that 1 T20 then you can remove a protective cover then the other 3 T20 and then its drops itself.
You can see in the picture that one of the brushes is shorter than the other one I think that was the issue.
I also did a battery test and the result was ‘charging okay’ 806EN of the 850EN.
Here is the OEM number for the voltage regulator: A 003 154 65 06. Because Mercedes does not have the part anymore I bought it form ERA it was about €35 orso.
Pros: issue fixed, charging okay
