Let's be clear, CARB and the EPA would have completely missed this. It was specifically the work by the students. I do wonder if it was pot luck they got hold of a VW Jetta. In the EU you have a similar cover up going on around diesel in general. For over 20 years people have known how bad diesel is, but the EU pushed it's low carbon emissions agenda promoting diesel cars and has not stepped back from it. Even now governments have successfully lobbied to relax the EU emissions limits. The realistic option is to ban the sale of diesel cars and require all other vehicles to be retrofitted with NOx filters.

> I do wonder if it was pot luck they got hold of a VW Jetta. IIRC the grant they received came from a European air pollution advocacy group which wanted to prove to European regulators that the EPA's stricter diesel emissions standards could be easily and affordably met with existing technology. The VW diesel cars were the only ones in the US after the newer standards came into effect which didn't use an SCR device so they would definitely have been included in the study specifically for that reason. The group also tested a BMW X3 diesel which did meet the standards in the same test that the VW models failed.

There was also a VW passat and the BMW was actually a BMW X5 that though had passed the CARB test and was at the legal limit in 4 out of 5 real conditions test cases went 10 times the legal limit on the test case that included downhill[2] [1]: https://en.wikipedia.org/wiki/International_Council_on_Clean_Transportation https://en.wikipedia.org/wiki/International_Council_on_Clean...
