VW Is Said to Cheat on Diesel Emissions;

[space-time]

Yes, about 10 years ago they used to put a sensor at the muffler to capture the actual gas and measure the CO, NO, etc. content. Now that is not longer used, all they do is connect something to the OBD port and read those parameters. Apparently the software detected when the test was being done: steering wheel was not moved, and many other tricks like this. Apparently some researchers put a sensor on some of these cars and drove them around to measure the actual emission content.

I am surprised how large the fine could be, some articles said over $37,000 PER CAR!. This is more than half the price of those cars! VW will be losing a lot of money and they deserve it.
