limp mode diesel particulate filter help (009315/009299/006744

[cochrank]

Group,

Driving today in my 2014 Jetta and the particulate light cluster came on. I drove it at @2300 RMP for well over 15 minutes. Id did not go out but then the glowplug light started flashing and it went into limp mode. The particulate light went out as well. I pulled over, shut off to hopefully clear the limp mode but it did not. After a long drive home put it on a VCDS to retrieve codes and tried clearing them but that did not work. Below is what came up:

Tried to force a regeneration because of my soot load:

When through the process to force regen while standing just for it to begin and then abort

I am hoping for the masters on here will tell me "Just need to hold your tongue his way" because I really do not know what to do next and I can't drive it the way it is and I don't want to take it to a dealer ship to say "you need to replace the intake manifold because of the P02015 error" (I am getting the dieselgeek fix after I figure out the particulate filter) because I know they will just replace parts until I am out of money or they fix the problem.

Any expert want to weigh in before my wife yells at me more (this is her car)

With all thanks!!!

I see the pictures did not make it so I will describe:

measuring block 241 gave me Particle filter oil ash volume: 108 ml, Soot load (g) calculated: 3.9 and Soot load(g) measured 56.4

When trying to force regen the screen gave me:
Status 144.0C/126.0C /0.0/00000010

Then it stopped after a few minutes and gave me:
Status 1.0/Abort/33.0

Hope this helps since the pictures did not come through

You need to replace the intake manifold and pressure sensor first, it won't regen otherwise. You may still need a DPF but don't/can't know yet.

 

[cochrank]

I need to replace the whole manifold or just the fix the intake flap motor limits with the dieselgeek bracket? Replacing the entire intake seems excessive if the PO2015 code is being caused by the intake flap motor moving beyond range.

When you say pressure sensor, which one are you referring to? If it is part# 076906051B
I seem to have 2 of these on my car it seems (in series since one of the hoses got from one to the other). I was getting a PO471 code which per ROSS-Tech WIKI was this sensor. I replace one of them but the code came back. I then switched the new one to the other one and the code has gone away but I do not know if that is because these other codes are covering it up. Is this code saying there is still a problem with the sensor? Bad sensor or wiring/fuse?

 

[cochrank]

Also is there any way to manually clean the DPF so one doesn't have to replace it?

 

[oilhammer]

You can try the DG bracket. I've had mixed results with them.

The DPF pressure sensor is the one on the bracket above the electric fuel pump. The EGR pressure sensor is the one on the back of the valve cover.

Also sometimes the tube gets soot inside of it.

If I were a betting man, I would place my bet that your DPF, and possibly the deNOx catalyst, are bad. But you won't be able to know this for certain until you get the other things fixed and working.

 

[cochrank]

Oilhammer, thanks for the feedback. Do these two sensors look the same? If so, maybe the one I purchased was faulty. Is there a trusted vendor to buy these from rather than the dealership?

 

[oilhammer]

On your 2014, both the sensors are the same, and I *think* the part number is still 076-906-051-B but there may be a newer revision.

Group,

An update. I performed the DG P2015 fix and it worked (no more code). I tried to do the regeneration while standing. It I guess performed it because it did the high idle process for like an hour before it stopped (stated "Abort' at the end. I do not know if that is normal). Still had the NOx regeneration error/light but the flashing glow plug and limp mode when away (along with the MIL light went away).

On the measuring block 241 after regen I was getting, 108 ml particle filter oil ash volume, 0.3 soot load calc. and 35.4 soot load measured.

I was reading that the regeneration should happen automatically if the car is held at ~ 2000 rpm for ~ 30 min. So I went for a drive. After about 40 min the MIL came on, the flashing glow plug and limp mode came back. I have the following errors:

Readiness block 241 is as follows: 108 ml particle filter oil ash volume, 4.8 soot load calc. and 56.4vsoot load measured

Tried to do a manual regen while standing once I limped back home but it will not complete it.

Group of wise people, what should be my next step?

 

[oilhammer]

Replace the DPF, reset the adaptation in the ECU so that it knows the DPF has been replaced, hope the deNOx catalyst has survived.

 

[ApproachMedium]

Side note to this, if you have the DPF cleaned, does the adaptation still get reset? i would assume such as it should be ready to accept more soot.

 

[oilhammer]

You do not "clean" these DPFs. You replace them.

 

[ApproachMedium]

The local place that cleans them says they can do it, and they have done them before. I also read a whole thing about supposed cracked ones being cleaned and solving the problem. For $300, ill see what they can do first. My budget is limited for buying the replacement right now at the 1200 for a whole new. It seems crazy to think this part lasts 100k when it should last the life of the car.

 

[cochrank]

Group, to give an update on this vehicle. Took it to VW and found ou it was still under the emission warranty (120,000 miles). They ended up replacing the DPF, NOx cat and the exhaust manifold. ~$5500 to VW. Shortly after my wide decided she wanted to see a deer up close and personal. Ended up buying another 2014 that is just starting to do the same thing but was able to get the other one back together and running well even after the insurance totaled it.

Moral of the story, listen to people that have wisdom because oilhammer was correct in the end. Just replace it and don't try to clean/regen. when it gets to that point.

 

[ApproachMedium]

I replaced mine the other day. what a hell of a job to do. started at 10pm and finished at 430 am. Id hate to ever have to do any of the sensors, you pretty much cant replace any of them except the nox sensors without removing the unit from the vehicle.

 

[oilhammer]

NOx sensor on the CJAA?

 

[turbodieseldyke]

I replaced mine the other day. what a hell of a job to do. started at 10pm and finished at 430 am.

You'd think that once they started getting a ton of failures (and paying for tons of labor hours), they would have redesigned it so the output pipe was clamped on instead of welded.

 

[ApproachMedium]

NOx sensor on the CJAA?

OK u can correct me if i am wrong, they LOOK like the NOX sensors on my LWN Canyon. There is one at the top of the DPF and there is one after the first cat. Are they just PM sensors?

EDIT: The Page on IDParts says they are oxygen sensors. huh. i guess thats a thing. oh well.
