I remember when you could buy a "Bosch" part and look at the box and in fine print it would say "Robert L. Bosch". My understanding was that "Robert L. Bosch" was an American company that used cheap foreign parts. We saw a lot of problems with them. Maybe they are still around and selling parts made in China with lead in them. They put it in everything else they make.
Just a thought.
