What I could never get a simple answer on though is this. If the management
was used in this so called low emission mode all the time, just how much
performance would you loose?
I am beginning to think that this is probably because no engine ever made
could pass the emissions standard on real life conditions of driving no
matter what you did. any standard that is not achievable is basically
pointless. What should be done is that a range of emissions under the
different conditions needs to be given and its up to the purchaser what they
decide to buy. and of course its up the regulators to decide on which list
they will support with their tax schemes.

"Volkswagen was reportedly warned about rigging emissions tests on its
vehicles years ago, not only by one of its suppliers but also the German
car giant's own engineers.

According to the Frankfurter Allgemeine Sonntagszeitung newspaper, VW's
technicians flagged up concerns about the engine management software the
company was using in its motors back in 2011.

It was also reported today that VW had been cautioned eight years ago not
to rig the tests by its software supplier Bosch. According to Bild am
Sonntag, Bosch had written to VW in 2007.

The cheatware detects when a motor undergoes emissions testing, and then
fudges the engine output to pass the examination by cutting performance to
meet emissions standards for nitrogen oxide."
