Precisely.

Then there wouldn't be much point in removing what you wittily describe
as "cheat mode", would there. AISB, that is the mode that will be
extended to cover ordinary use.

Or you remove "cheat mode", retest a sample of affected vehicles in
"ordinary use mode" and re-write the spec and change VED band if
required for new vehicles.

VAG pick up the tab for any increase in VED on *new* vehicles. There
is no issue about emissions or performance as those figures should
now be correct.

Existing vehicles stay were they are as far as VED is concerned, as
is the case with older vehicles when they fiddle with VED?

The owners are given the option to remain with "ordinary use mode"
and be given the true emission and MPG figures, have the car flashed
to "cheat mode" maybe taking a performance hit but getting the
previously published "cheat" emissions and MPG figures or VAG buy
back the car as "not as described".
