Hello,
I tried this and reduced the mesh to 30000 E with the reduce mesh command, only 3 self intersect surfaces remained. How can I reset those 3 surfaces?

You can upload .obj to Fusion and triangulate and decimate there.
Shrinkwrapping is the quickest way to fix overlapping / self intersecting meshes.
