It seems like there are more and more articles where States/Governments (France, Germany, etc.) are hinting that all of these diesel vehicle makers are using "defeat" devices to get by NOx regs, one has to ask if the "regulators" perhaps drew (out of thin air) the NOx standards for diesels too high, without any input (because they didn't care and wanted to get rid of light pax diesel,) from the auto makers and whether or not if they could easily/fiscally achieve those levels?
One article that I read hinted that in VW's case for the 3.0L TDI's in the Touareg, they could meet the NOx standard by dumping a bunch of DEF into the exhaust, but then you'd only get around 3k miles per tank of DEF, instead of the marketing department ask for 10,000 miles, or one OCI, (oil change interval.) So they went back and adjusted the DEF levels and ECU to get by the test as the EPA designed, and we got we know it as now.
Not sure how new this suit is, the article is less than 24 hours old. Essentially claiming the same thing as what VW was accused/found guilty of, and seeks class status. Citing the added expense of the diesel option, it sounds like they are seeking compensation a la VW.
