Bosch pays 90-million-euro fine over diesel scandal – DW – 05/23/2019
The penalty may be significantly less than the ones handed out to Volkswagen, Audi and Porsche, but auto parts supplier Bosch has become the latest big-name casualty of the "Dieselgate" scandal.www.dw.com
Bosch got asked to develop the device that can cheat for "testing purposes".. So you could activate & deactivate it via software. On delivery they told the manufacturers: You must not enable it, or you will break the law. The manufacturers did anyway.
In Germany you can only get liability on the individual if you can prove that this individual was responsible. And all the engineers got papers covering their asses that they were told (and underwritten!) by management that they should implement it..
Still awful .. but being in Boschs shoes: .. "Well.. would be sad if VW would order these control units in China, wouldn't it?"-kind of situation..
Thats why they only got a small fine.
