Quite a mess and a bit sad really - I have worked for a German multi-national, multi billion € company for over 26 years now, and they take these matters of tests and documentation really seriously - shame on you VW - heads are going to have to roll over this ?
Heard on the news this morning that over a million UK cars could be recalled, although if we believe the statement from VW mentioned above, then drivers of MK7 Dervs with the Euro 6 compliant engines are immune from these (so my GTD for instance), although I'm sure everyone of it's emission tests in all markets around the world will be under scrutiny now.
Wonder if this is just the VW brand or also Audi (which is massive in the US), as well as Skoda, Seat etc. ? I also wonder how many other manufacturers are playing the same game but just haven't been found out.
Whilst it's bad for VW (very bad), maybe some good will come out of this, as things like the emission and European official fuel consumption tests will now hopefully be adapted for something approaching real world conditions - not laboratory.
