Ok this seems to be another problem. I printed a wall that is 0,5 mm and the nozzle size is 0,4 mm. So the extruder printed the first line ~0,4 mm and had to place a second line with 0,1 mm next to it. Therefore it had to adjust the extrusion speed. It seems that some calculations interfere with the small feature setting. So when a small feature is printed, it slows down the movement. When it now calculates the extrusion speed, there seem to be slight differences to the parts that are not small feature. So the problem with this part seems to be unrelated to the wall problem of this topic.
I did some further testing. I also printed a "normal" part without any holes and it looks quite good. So I would assume that the problem is not a mechanical one of my printer, but of the slicer settings. It does not really look like the classical underextrusion, but I am not sure. I allso attached the G-Code of the example bad part, maybe someone would like to test if they observe the same behaviour?
