AVDigitale you are right. For DPF off in this ecu you need read Full BDM! By obd you can't close egr/dpf for 100%.
And MPPS china clone, you can use this tool for 5 or 10 times and hardware is die.. Very big shit.

For CMD: Very good tool, but some new ecu's (like dcm) will some times crash after done by obd.
My experience: Need geniune kess + magic + CMD for do all ecu's by obd, otherwise read/write with tricore for new ecu's.

CMD works very good without any issue for old ecu's, i never had problems with edc15 and edc16, always 100% by obd.
