My question is HOW did the car *know* it was being *tested* for
emissions?

It seems like everyone here is on a VW witch hunt.
I would expect VW to program it's black boxes to use the minimum fuel
for a given situation. If the car is on a dyno, there would be no
wind resistance to push
against so the fuel system *should* lower the fuel flow. I'd expect
the same behavior if I was rolling down a mountain grade. Sheeeesh!

Wow! Cluelessness at it's best!

Update 9/22: This morning VW announced that the cheating issue on diesel engines
is much more vast than initially expected. The company admitted to cheating on
11 million diesel engines worldwide.


Wonder about MB and BMW Diesel vehicles. I was looking at MB GLK-250
Diesel version when news broke out. Considering Diesel vehicle for next
new car purchase is on hold now. Also I am wondering about turbo charged
small engines on almost every cars, Ecoboost, Skyactive...,etc. Crap.
BMW and MB use DEF - I believe it wsas only Volkswagen's "clean diesel
technology" that did not - and now we know how THAT worked.
