Folks,
Dash warning came up the other day, "engine malfunction", a few minutes into a long drive...nil physical symptoms.
-
90 miles into the journey, popped into independent garage and P244c-00-6d was the reason. (DPF failed to reach sufficient temp for regen.)
-
He noted DPF pressure differential was 10kpa (100mbar?....but I cannot remember if this was at idle or whilst raising revs.), and explained this suggested the DPF was partially blocked, it had attempted to do a regen, and failed to do complete it due to above error.
-
He also explained vaporiser (diesel injector), and its function, just upstream of DPF, and suggested it may be the issue.(blocked?)
-
I was on my way up to the Midlands, so I (stupidly?)requested he cleared DTC, and that I would give it a good thrashing in 4th for 20 mins and monitor to see if the MIL returned. (my risk)
-
I have subsequently covered best part of 6 hrs motorway driving since then, along with maybe 5 hrs local driving, with no further issues.
-
Ordered ELM327, downloaded Forscan, and scoured the web for many hours learning about the injector/glowplug/4Hz pump etc.
-
Unfortunately, I have no idea if it has had a successful regen or not, since the dash warning, as I don't have any PID relating to DIST_REGEN available to view.
----------------------------------------------------------------------------------------------
------------------------------------------------------------------------------------------------
I took it for a short drive, Forscan connected and observed:-
DPF_DP Varied between 0 and 9kPa (between 800 and 2200rpm)
DPF_SOOT 38%
DPF_LOAD 51%
------------------------------------------------------------------------------------------------
Sat in car park, and revved up, stationary, to 3900rpm for 10 secs:-
DPF_DP absolute max of 8kPa
----------------------------------------------------------------------------------------------
----------------------------------------------------------------------------------------------
I have spent most of the afternoon searching, and can't for the life of me find any information on typical DPF pressure differential values.
-
Please shout if you have the answer, or can offer any advice on the basis of the above information.
-
Many thanks!!
