Ford Galaxy 2.0TDCI dpf monitoring

[drjaking]

The engine message came on during a long journey. Fault code was P269f, which is the fuel vaporizer fuse/open circuit. After restarting the car, the message went away. This seems to be a possible predictor of dpf failure so I've been monitoring the PIDS that seem relevant: dp_dpf, dpf_load and dpf_soot_ld. But I don't know what to look for. Dpf_ld is 62%, dpf_soot_ld is 72% and slowly rising. Dp_dpf is 0 at idle, rising up towards 10kpa on acceleration.

Any advice would be appreciated. When would a regeneration happen, and can I trigger one?

DPF failure - do you mean blocked DPF?

DP_DPF shows differential pressure on DPF, this is a measured parameter. It can be it range from 0 for no load/clean DPF to 15-20 kPa for high load. DPF_LOAD and DPF_SOOT_LD are estimated parameters that are calculated by PCM from the differential pressure. We are not strong in DPF theory but assume these 2 PIDs mean the same but calculated in 2 different methods. DPF_LOAD - inferred closed loop and DPF_SOOT_LD - inferred open loop.

In any case, in our opinion these PIDs show your DPF filter is quite loaded and probably a regeneration is necessary.

Any advice would be appreciated. When would a regeneration happen, and can I trigger one?

Regeneration should start automatically in certain conditions, for example during a driver on a higway. We don't know about exact conditions, there should be owners here who monitored the regen conditions so they may answer better, Also, it is possible to start so called static regeneration. Isn't DPF static regeneration item present in the Service chapter of FORScan?

Check fuse from fuel vapouriser, and glowplug in vapouriser. Check that vapouriser is not clogged. I have changed a lot of them...
After replace vapouriser make dpf adaptation an go on the road. You will see dpf temperature over 600°C and drive untill drops to 300-350.
