I figured out that it was not active regening but due to the previously long trips it never caused an issue as it was still passively slow oxidising. I renewed thermostats, exhaust gas temp sensors, glow plugs.
Got a c110 scanner to monitor and clear errors. Got it active regening again, but now have deflapped and it seems to definately block the dpf sooner.
As soon as the ecu logs the 480a error for partial dpf block it will not active regen. I can't force a regen with the c110, only clear codes logged. Thus the ecu will not even try to active regen for the max driving profile of around 250miles as clearing the codes dummies the ecu to believe there is no need for a regen...yet as soon as it generates a code...it will not regen.
A bit of error loop in the dpf regen cycles program logic me thinks
Thats great information to know, and i can see the problem with the regeneration and you could probably do with the Carly app or ISTA+ or INPA so that you could clear the codes immediately followed by a regen request which some people refer to that procedure as a "forced regen". It is interesting that Andy (the guy who posted after you) mentioned that he has no issues so far but i believe he has the newer N57 while we have the M57.. it would be interesting to know if its just you who has the relatively quick dpf partial block or whether the M57 bungs quicker than the N57.. this is why i thought it would ve interesting to probe a bit more into how peoples cars are with the remaps with the dpf.
