There were also unconfirmed reports on Monday that senior R&D heads working across the car group had been suspended. Reuters said the suspensions involved staff from the Audi, Porsche and the VW brands.

That's not news--I heard a number of senior R&D management people at the Volkswagen Group were suspended last Friday as part of VW CEO Martin Winterkorn's resignation. In fact, the German ADAC and TüV have begun to retest every diesel model sold in Germany in recent years to make sure they are in compliance with Euro 5 and Euro 6 emission standards.

Interestingly, the upcoming Euro 7 emissions standard coming circa 2018 could effectively obsolete turbodiesel engines; that's why there's a lot of research into homogeneous charge compression-ignition engines fueled by gasoline (petrol), which could offer diesel-like fuel economy but with gasoline engine-like emission levels.
