I had similar problems, I changed from flex pipe to nox sensor, clamps and gaskets, but still it didn't help, I went to dealership and one guy told me since your truck has 1.8 milion km it's catalyst that is giving you a problem, change it, it will fix your problem, he said rather buy used one from some truck with low mileage than aftermarket, I changed catalyst and all problems related to scr and dpf are gone. New catalyst in Canada is 8000$, I found good used one for 3K.
