The cars can meet the standards as built.

For how long? There's a big difference between
fifteen minutes at the inspection shop and
two hours of roadway driving.

that will be affected. For example, IDK how the overall
system is designed and it would seem possible that maybe
other parts of the system can't endure the constant operation?
That would be worse case. Even if it's MPG only, they are
still going to be in big trouble if the cars don't meet
the advertised MPG. That would likely require some refund
payments to the owners in addition to fines, possible criminal
proceedings, etc.

And.. if the MPG hit is bad, VW could be
running into CAFE issues...

Yes, if fixing teh code causes the mpg to go down it's possible that
VW would then be on the hook for false MPG claims. Kia or one of
those smaller companies got hit with fines for that not that long ago.
