Ducato 2.3 2017 twin egr.

previously had engine with 180tkm on it, changed engine to a 70tkm but kept a cleaned DPF including its sensors.

Swedish inspection checks exhaust soot levels ("K-value") and this "new" engine did not pass even remotely close to approved levels. I can see a small burst of soot when engaging throttle and pushing above 3000rpm or so..

Error code is P2000-97 NOx Trap Efficiency

Runs just fine otherwise. Not much used.

My thoughts:
Injectors are not coded correctly at this point (separate thread about multiecuscan problems with 7-8 digit bosch codes). And I'm seeing one injector have a setting that seems a bit more "out" then the others. Perhaps this creates the soot and would be solved after correct coding?

Perhaps I should perform a forced regen of dpf?

Bad lambda sensor?

Worst case change dpf?


Attaching some data that I hope can be of use..

I don't have any specific information about yours but in the past with electronics on modern engines I have changed everything from the old to the new, from high pressure pump to electronic injectors including putting them in their original position and car ran as before but with good engine.

Engine I 28-7-22l injector variation.jpg

A very quick look at your data shows the injector variation is well out of spec.
2
3 threads to have a read, very relevant but a lot of it



 
Thanks! I figured it might be so. I guess correct coding of the injectors is a first start. (New uncoded injectors. Having software issues for the acceptanve of the Bosch codes ..)
 
Was the engine cold
if you can Repeat the test on a run until warm and at least 10-15mins after
Engine I 28-7-22 LPEGR.jpg



The LPEGR positions are fine .
the temperature is extreamly low good engine achieve better than 100 °C. This is generaly believed to be due to a blocked LPEGR cooler
The Lamda values are concerning., though similar results are seen initialy in a cold engine. There was no coolant temp to check. The LPEGR results could be due to a cold engine.

yeah It was fairly cold I guess.

I'm a little bit afraid to run it when I see the data of the particle filter increasing per second.. seems like its filling alot of soot in there.
Will try to sort out coding of new injectors first..

Multiecuscan yes! bought a specific adapter --> https://www.ebay.com/itm/354098173094 can read things fine but when trying to code new injector values I have 8 letters on the injector and 7 shown in mes.. and error wehen trying to update.

This thread has info about coding injectors and the throuble the guy is having also with his Lamda sensors

 
So adding some more data. Apparently my WIFI ELM327 unit (bought from a MES specific dealer) was not quick enough to compute the injector code updates. a cable connected elm was needed for that. (went to a mechanic instead.). So noticed that the car still has some black smoke when acceleration hard. I would say perhaps not as much as before. But still.
Adding more data - from a warm engine both heating up and idling.

Adding a cleaner run. Just a few km's driving home slow and some idling at home.

Runs just fine, could it be old soot still remaining that I noticed? I have also reset many of the sensors via MES and AlfaODB because of new engine, could there be a long run needed to have these sensors set themselfes?

So currently no error codes appear. Its just the soot i'm worried about. and not passing a revisit to the inspection :)
 
Will look at the data tommorrow the injector values still look high.
There is a setting in Mes F7 adjustments Reset self learned functions. If other items have been replaced this section may give aditional information (eg air flow meter crank balence (if new engine) egr learn, DPF sensor
 
Ok thanks for the assist! I'll have a look at the f7 function tomorrow as well
 
May not be relevant but I had a Doblo with loads of black smoke, eventually I found the fault was the wires and connections just before the MAF sensor. That showed up with an Ohm meter and probe through the wires for continuity.
 
Irregularities in MAF-sensor should show on MES scans somehow?

I realized I have coded injectors 1-2-3-4 calculating from the left to the right when standing in front of the engine looking at the windshield.. could I have done it the wrong way?

Google seems to state that I have done correct. Ill try driving the car on a longer trip now to see if that might do any changes.. also try the f7 thing. I have tried to reset things via alfaodb software but cannot remember any air-controllers reset at that point.
 
So with some risks of spamming this thread I did reset some things under f7 (I realize now I did not use "reset self learned " because the description did not state any emission related things?

Drove 30 km x 2. this measurment is from the last run. I noticed smoke when accelerating 3000rpm under load in the beginning but not so much in the end?! So perhaps the end of the file states that things are better :)

Looking at the injector data, can someone explain why injector compensation on some injectors are mirrored ?
