There are a lot of versions of this one.

I have worked on an MJD 6F3 HW03R.D1 with DPF, and its been a nightmare to get a backup taken. Only managed through BDM... Galetto 1260 uses a similar (but not the same) protocol, Kessv2 reads only on the bench via Kline and crashes at the end....

You need to remove the 0 ohm resistor and read it through BDM. Do have a backup taken before messing with it though as the DPF removal procedure touches a lot of points on this ECU
