How the software "fix" improved emissions and driving quality.

German article about the measurements after the "dieselgate update"

https://www.adac.de/-/media/pdf/tet/...004EC4CBE009F3

Very briefly: up to 25% improvement in emission reduction and no loss of power. On the contrary, they even have 7 percent more power than specified. Both the torque- and power curve has flattened but also starts earlier, which is consistent with my experience.



But why was this not possible before? And at what cost?
I think the benefits are achieved by triggering a different driving behavior by boosting the power at low RPM. But certainly due to more internal pollution of the engine -> more use of EGR and more frequent regeneration of the diesel particulate filter. Time will tell ...
