dpf and engine management light
 

Hi everyone, I'm new to the club. I have a '56 Mazda 3 1.6 diesel.
Some months ago the engine management light came on.I had a read out and the following codes recorded. P2584 Fuel additive control module MIL request- Intermittent.
FACM - P1927 P1932 P1922 B1317 all intermittent

The light went out a few days later and stayed out, the other day the car suddenly stopped and wouldn't start. I got it started but it seemed to blow out white smoke and then I drove it it forward about 100yds and then it stopped again and wouldn't start. Towed it home and next day tried to start it it started but seems to run very"lumpy" and will not accelerate. I have looked under the car for the dpf fluid container, it appears empty. Not sure what to do now Fill up the fluid, remove the dpf and clean it.
Has anyone any ideas have a knackered it by driving. I am told the if the dpf is blocked there will be back pressure which could do some damage.
Sorry this is longwinded but my knowledge is limited and I could do with some help
Thanks .Regards Bill
