De-sulphating Nox-storage-cat

Hello, someone knows how the process with the current Euro 6 diesels runs, or I am interested in the PSA DW 10 2.0 with 180hp background: I received an update from Ford in May due to a calibration error that can lead to increase Nox emissions. In June he then regenerated the DPF 5 times in a row, the last time on the AB on vacation. Yesterday I am going home, shortly afterwards the regeneration started again 5km village and country road then 7km constant 100 km/h on the flat country road. There the regeneration was finished. This morning on the way home he started already again. Now I thought maybe a de-sulphatization is necessary and the necessary exhaust gas temperatures are not reached on the country road?
