Re: Something I have long wondered about...
Within a year of the original scandal, every single manufacturer of Diesel engines for personal cars in the entire world was caught red-handed.
Have you any proof about that?
engine control electronics for all engines found to be cheating were made by Bosch.
AFAIK, Bosch made it clear the software was for test and evaluation only and shouldn't be used in the wild, something VW decided to sit on it.
