hi all today I did a static regen on the above car as there were a code stored (can't remember which one) but it was a regen failure code. I started the regen which ran without problem for almost 40minutes? to which it went into cool down procedure and at the end said failed to complete?? is this pointing toward the dpf being to blocked? it did say something about timing out and I thought it was taking a long time when it was running compared to when I did my cmax 1.6 some months back? I live in a small island so diesel is not the best car obviously for the short distances and probably the cause of the trouble in the first place! is it worth doing another or will it only be resolved by replacing it which I'm not prepared to do at those prices for a new one! any help would be welcomed cheers richard.
hi I have scanned again and no code I'm almost certain it was a failed region code and it hasn't tried since. anyway I did another regent using for scan today and this was my findings. whilst driving warming up the car before regen I monitered the dpf load which was 40% and both cat temp sensors were around 230c the dpf kpa were 0 at idle though. anyway I pulled up and did the regen which ran for over 30minutes (actual regen time not warm up or cool down) and ended up cancelling the run at 75% as it looked like it was going to time out again! after finishing the regen I pulled up the pid's again and cat temps were only around high 200's just breeching 300's I think but the dpf load was 0.0 % so I thought good news surly? anyway took it for a bit of a hard run to see what it was like and left the live data running after around 5 min the dpf load was up to 34% ? is this normal does this not mean the dpf is 34% full or am I misunderstanding the readings?
Right, at that high a % it is dangerous to do a regen. There is a high risk of burning the car down. Take it down and clean it, don,t forget the pipes to sensor will need cleaning also. A regen can get temperatures of 600 deg c.
