We reluctantly turned in my wife’s A3 TDI to VAG for the buyback. It was a fine low mileage car with nothing wrong with it. Still looked brand new. We replaced it with an Audi Q5 with the 3.0 supercharged gasoline engine. The fines and penalties to VW were supposed to be about emissions but what is the carbon cost to our planet of taking perfectly good cars off the road, that will go 45 miles on a gallon of diesel, and replacing them with bigger, heavier SUVs? We have yet to see a tank average over 25mpg.
Ironically, I am still driving the 04 Golf TDI with a tune and a hotter thermostat with higher NOx and particulate emissions than the A3 ever did. And the A3 will probably end up in the crusher.
