Mercedes, VW and pretty much the rest of them cheated the sniffers by putting it in a clean mode when it was on the rolling road (probably by testing suspension travel and steering angles in the traction control software/hardware). They caught VW first with a mobile sniffer test under normal driving. Since then they found Volvo, Renault, Jeep and a bunch of others are doing similar bullshit.
Clean mode probably cut the power output in half and would have made them drive like the non-turbo diesels of yore.
Disclaimer: I’m actually a car enthusiast/nerd, but I’d like to see cars become the opposite of how bikes are used in my area. Weekend hobbies that are used for enjoyment or maybe to go traveling out of the reach of infrastructure. Not to slog to an office everyday in 4000lbs of hydrocarbon powered metal.
At this point I’m sure everyone has cheated and surprised they don’t go back to sniffers instead of OBD.

That’s super informative and I didn’t realize it was that technical. Thanks fren!
