Good example of sand in the face
Sure VW did bad. Stupendous, organised, idiotic, bad for profit:
BUT
They were being watched (and people paid for those emissions tests) by employees of nation states. These employees of the states and the people they represent didn't notice this for years. Even when the scientific results came in (April/May 2014) nothing noticeable happened immediately. Don't let sand be kicked in your face. Much more is rotten and useless here than VW.
If they try to put a noose around the neck of a scapegoat or two, those scapegoats (and those who know the truth) should spill absolutely all the beans and not lose any pension... for doing that. Come to think of it details should be spilled irrespective of scapegoating.
