Or do the right thing and leave the cars alone. The world hasn't come to a halt because of some excess NOx emissions under certain load conditions, so in actuality no harm no foul. Pay a few million in fines, get your hand slapped, and move on with life.

Your solution is great.

However...rest assured it'll never get implented because some long-haired, Gaia-worshipping, granola-eating, Birkenstock-wearing, butt-ugly libtard freak (male or female) will come protesting with their brain-dead fellow travellers, weeping before the cameras, screaming, "The Erf is dyyyyyiiiinnnnngggg!!!!!! Somebody saaaave the Errrrffffff!!!!!"

I saw a woman being interviewed a couple days ago when this first broke.
She was really upset and said she was parking her newly bought TDI.
Crazy

If I owned a TDI I'd do my best to ignore any fixes that may be coming down the pike.
