Is DPF issue for 2014 CRD fixed now?

G'Day all,

I've read a ton of threads here that mention the DPF and "Limp Mode" dramas with the 2014 CRD, but they don't actually confirm if the DPF issue in Australia is actually fixed now. Apologies if the fix has been mentioned here, but I can't find that thread.

After many months of working extremely hard to convince the "hugs & kisses" that the 2014 (or 2015) Jeep Grand Cherokee WILL be much more reliable than our previous 2000 WJ-Limited V8, I'd hate for the DPF issue to crop up with the new JGC.

If the DPF Limp Mode happens to my wife while I'm working interstate, it will not be pretty, and I will be in more trouble than Ned Kelly :eek:

To be safe should I go with the HEMI? Apart from a higher fuel usage rate, it isn't hampered by the "apparent" CRD's DPF problem.

Any comments, recommendations or reassurances are greatly appreciated.

Cheers,

Marty

Yes, well - they are currently my first point of contact with Jeep - Im hoping my last if they give me back my confidence in my gorgeous jeep. Im sure warranty work sucks for all the service centres when they no doubt already have full loads but I didnt part with my good $$$$ to have a car go into limp mode without any warning - just not good enough. She will be away for at least a week by the looks of things - they can't get a good look at her till next Monday - she went in on Tuesday morning. x
I've read your story and am really sorry for the trouble you are having. You say that the dealer cannot look at your car until next Monday - frankly, and I'm sure you know, this is simply not good enough! My advice is to kick and scream as much as possible - you need to DEMAND that your car be given priority for a known endemic failure with the GC. I'd be making JA in Melbourne your first point of contact - ring Glenn Jones and insist that he take over control and liaison with the numb scull dealer. You should not be left to resolve this issue with the dealer by yourself.

I agree, contact Jeep Customer Care and tell them that the situation is unacceptable.

1300 133 079

I know its a pain right now, but once they have it fixed you will be able to enjoy your Jeep again. This is the only widespread issue for this car right now, so once you are past it, things should be all good.

ACCC and NCAT have simple online complaint lodgment forms - spend 10 minutes of your time and get a registration number. It takes several weeks for NCAT to take matters up but you can at least demonstrate to your dealer that you are deadly serious. Worked for me.

I notice even early on page#1 a software problem is presumed as the likely cause.
Would like to see if it happens to anyone (hopefully doesnt) who had the last update.
 
#655 ·
Thanks Steve, my update - flash (December software update) performed today with forced regen and I pick her up tomorrow. I will definitely let you know how I go. My Service Guy said that there has been problems and this upgrade should fix it (just bad timing that it came out only 2 weeks after it did the first time). Im praying (I'm not religious but I can't think of anything else to do) - that it does not happen again. Very keen to see some signs of active regen that it performs itself. Still feel not impressed that none of this information is anywhere to be seen in the manual ??? Samantha. x

Hi all. Iv got an Nov 13 build date ecodiesel grand cherokee and haven't had any dpf issues to date. The regeneration occurring message popped up once while my wife was driving and even tho she wasn't on the highway it (20min stop start city trip) it managed to complete is successfully. We've done 14,000km to date and have noticed a burning smell from the rear after a trip on at least 3 occasions over the last 10 months. We assumed it had done a regen even tho there was no message. Hope that bit of info helps! Oh and it's my wife's car so she mainly does city driving to visit friends and parents, tho do we like to drive abit further on weekends and have done 2 long range camping trips the last couple of months.
 
#657 ·
I also think Jeep should program a manual regen option if this issue keeps happening. It should be activated by the user by pressing some button 3 times, then activate when the vehicle is going faster than say 70kmh. If the speed drops before it finished then the regen should stop. If the automatic method isn't working as it should at least this would give us more peace of mind by giving us the ability to clear the filter before Offroad trips etc.

Steve - great info. Worth send to JA?

Well I took a print out of the Audio/Nav patch in to the dealer today. Fortunately I got a very experienced Canadian service tech who has worked with Chrysler for 30 + years. He eventually logged on to Chrysler in the US and found the patch I gave him, plus one other patch, which will apparently fix a whole host of Nav system problems. (Some drivers in the Gold Coast have been directed out to sea by this system.)

It took over 2 hours to download the patches from the States.

He said that in one dealership in the Gold Coast, they were getting 5 cars in every day with DPF problems. He told me that it's a problem inherent in this kind of system, and that it's even worse in the Volkswagon diesel 4WDs.

Apparently, one of the problems is that they lie idle at the Port for 2-3 months before being shipped. Any idle periods like this will make the problem worse.

It's apparent that the recalls and other service bulletins are not being applied to new vehicles. They don't even send out letters with recalls like most manufacturers.

It might be useful to others with 2014 GCs, so here are the software patches that were applied:

RRT 14-009 and RO408143.

Yesterday, they charged me $84.70 for trying and failing to find these patches. Today I was credited for that. So I feel grateful, but also vindicated.

Hi all - I don't think I put my car specs up earlier - my black beauty is built Sept 13; compliance Nov 13; JGC Summit WK MY14 bought as a demo from Sutton City Rosebery May 14 - just under 5,000km on the clock. They aren't our local dealer (we live on the South Coast) but ours is still a 45min drive back up the Coast (Nowra). I must say when we booked her in for a tow bar in Nov 14 they also did updates that were required (and of course the two recalls that came out too - one we knew about via notification from Jeep and one that was very new). I do certainly hope my problems stop after receiving her back tomorrow. Can someone tell me please - so there is no notification from the car that it is doing a regen at any time (so I can keep an eye out for it) ? If there isn't - what are the signs to look out for ? higher temp ? smells ? Any info would be greatly appreciated. Thanks. Samantha.

Samantha.

Most times you will not see anything if the car does what it should. The only time you will now about a regen is when it is getting near full and a regen has not been successfully completed due to usage (this was told to me by the garage). When the regen occurs it is logged. Mine had done about 30 successful regens before a DPF full incident in November (23000km). I had only seen one message at about 7000 kms. I have seen one message in early Jan saying 90% full, drive at highway speeds to rectify and the % figure slowly counts down in 10% increments until completed. The message that I see is similar to the DPF full screen that you probably saw. In other words when it is happening you will know. Attached is the message I got in November when the thing threw the teddy out of the cot!!

Adrian

My MY-14 GC went in for a recall today - the Steering Column one - as I stomped in, I had full intention of insisting that they do the latest up date to solve/fix/bandaid/pretend to cure the DPF issue.

You could have knocked me over with a feather - not long after finding my paperwork, and before I could say anything other than my name. They said they were doing 3 updates - one of these was the DPF (I do remember 04 as an end number on the update, I think I was still in shock).

Keep your fingers crossed, as I'm getting twitchy that my DPF is filling quickly..................all that stop, start driving I do, that a previous tech said was the cause of my DPF issue................he didn't take in to account the 300km highway driving I do every 3 or 4 weeks :cool:
 
#667 ·
I am at least one unhappy DPF effected customer that received a written reply from Jeep admitting the problem they had. The day after our GC had a manual burn, to rectify the same old limp mode DPF issue I emailed a very lengthy letter voicing our disappointment in Jeep for letting this annoying and possibly dangerous, problem continue on for months (I had been watching this and other forums) and appear to swan along, soaking up increasing sales, whilst their existing customers were having to except the ongoing saga all here know all to well. I wrote my letter on the 25th of Nov. and received this reply the next day, from Customer Care.
" In regard to the concern with the DPF, I would like to assure you that we are working closely with our technical team to resolve this problem as quickly as possible.
WE will certainly not ignore it and I just want to assure you that Chrysler takes very seriously our customers and their concerns.
We are hoping to have a fix for this concern shortly".
I had the December 18th update flashed last Monday.
 
#669 ·
Thanks for your post, you are correct, this has dragged on far too long. There was obviously a pattern to the issue with the problem affecting MY14 cars far more than the previous car. So obviously something changed. For a long time dealers had been blaming diesel quality and driving style, etc. it was all BS, and seemed to simply be a deflection of blame so they didn't have to fix the problem.

I wonder if one reason for this is that with the diesel being a low volume seller in the US, Jeep Australia had difficulty getting them to troubleshoot and identify the cause with any priority.

Anyway, hopefully this update fixes it for the majority, there is still the potential for sensors to die or tubes to be bent, but hopefully this issue will be heard of far less now.

Never knew or was told about this DPF problem when buying my Overland GC. It was a special build due to the colour (True Blue) and took six months to arrive from ordering, build date 06/14. Got the car September 2014 and on the October long week end travelled to Toowoomba from Sydney and return (3000k's), ran like a dream, no problems. Got home did some short trips and medium length trips then at 5266 k's got the message "nearly full drive at highway speeds" and the car went into limp mode within 10 seconds. Took the car to the dealer they did the "forced regeneration and rest all values". All good for the next six weeks and guess what same thing again this time at 7214'ks.

Spoke with dealership service and suggest they update the software with the RRT 14-104 flash. Got the car back today with the updated software, let's see what happens.

Just as a side line up until today have never seen, informed or warned of a regeneration taking place. Also have never had any warnings about the filter level.

I am up to 8500km now and touch wood no DPF issue yet (bet I now get one on the way home today). MY14 06/2014 build and always ran BP Ultimate. No towing and 70% of the total kms would be freeway driving.

I have seen my instant fuel consumption spike by 2-3L for no reason when driving on fwy with cruise set to ~100km/h and this lasts for 10-15km and than goes back to the normal 6-7L.

I have never had a regen message come up on the EVIC. I will ask the dealer at the 10k service to let me know if my car has had a successful regen or if the DPF has just been slowly filling up.
 
#673 ·
We also have had no Active Regen message on the EVIC. (Steve1307, I know you have me down as a positive regen happening but I think you must have misinterpreted my posts).

MY14 Overland (Build date - April 5th 2013 so an early build), 42,000kms now, 18 months of ownership and no DPF issues.

On occasion I detect a burning smell from the rear but that is because I have to stop half-way up to the house and open/close a gate (engine still running) so I am behind the vehicle still running but in park, when I notice it.

RRT 14-104 was applied (unasked for) at the 40,000 service.

QPR39 is right. It's just a case of waiting to see whether this TSB has corrected the issue.

I'm going to look for that OBD Facile App. I have an Android phone.

From the US Diesel Supplement*, but not in any Australian documentation:

Exhaust Filter XX% Full Safely Drive at Highway Speeds—

"This message will be displayed in the Electronic Vehicle Information Center (EVIC) if the exhaust particulate filter reaches 80% of its maxi
mum storage capacity. Under conditions of exclusive short duration and low speed driving cycles, your diesel engine and exhaust after-treatment system may never reach the conditions required to cleanse the filter to remove the trapped PM. If this occurs, the “Exhaust Filter XX% Full Safely Drive at Highway Speeds to Remedy” message will be displayed in the EVIC. If • Exhaust Service Required — See Dealer Now — This this message is displayed, you will hear one chime to assist in alerting you of this condition. By simply driving your vehicle at highway speeds for up to 20 minutes, you can remedy the condition in the particulate filter system and allow your diesel engine and exhaust after-treatment system to cleanse the filter to remove the trapped PM and restore the system to normal operating condition."

*2014 Jeep Grand Cherokee Owners Manual Diesel Supplement, page 24.

I'm going to look for that OBD Facile App. I have an Android phone.
Yes that's the only app i could find with more of the OBD parameters that seem to be supported by the Jeep. ( For me, the app keeps dropping the connection to my OBD dongle so its a bit of a pain)

The "Normalized DPF % " is one of the standard parameters (not a Jeep proprietary one), so i'm waiting to see if it is actually the one used by the jeep.

Its not on this Wikipedia page either: OBD-II PIDs - Wikipedia, the free encyclopedia.
It's not the first time wikipedia has failed me.

I managed to work out the codes for that parameter it so now i've entered it as custom PID item on a "dashboard" on another more stable app.

The DPF data is accessed with Mode 1 - PID 8B which gives 7 bytes of data.
The first byte "A" gives the info of which of the other 6bytes are supported.

2nd one, byte "B" is the current Regen status and SCR status in bitwise form.

3rd one , byte "C" is a value which is a calculated value to display as a percentage.
standard SAE J1979 said:
DPF_REGEN_PCT shall indicate the normalized DPF loading, time, distance, drive cycles or other criteria before the next DPF regen where 0% means the DPF is clean (a regen just occurred) and 100% means the DPF is fully loaded. When there are multiple criteria to trigger a regen, the one that is closest to triggering the regen shall be displayed.
The byte range is from 00000000 to 11111111 which is 0 - 255 in decimal.

if we are scaling it from 0-100% the equation i used is: C*100/255

Some apps like "Torque" will let you add your own custom PIDs if you know the address and the scaling equation.

I entered it as a custom in my app like this:
Name: DPF % full
Mode: 01
PID: 8B
min: 0
max: 100
units : %
Equation: C*100/255.

This displays a percentage which matches OBD facile.

my Dashboard display looks like this


As you can see it's filling up 28% :eek: earlier this week it was 16%.
I'm assuming that Jeep scales from 0-100% for their EVIC. maybe they think 120% full is a valid number.:confused:
Waiting for it to get to 80% or 100%. see what happens
 
#677 ·
Does anybody have the spec on the DPF?
Talk to Bosch. They make really good dishwashers and washing machines - not so sure about CRD systems. (kidding) ;)

MultiJet II's Bosch-made injectors can manage up to eight highly precise injections per combustion event. Bosch also supplies the system's high-pressure pump, sensors and engine control unit in addition to the vehicle's emission system, which includes the diesel particulate filter and selective catalytic reduction system.

The guy in Alaska posted in this thread #254.
He lives in Skagway, a small town squished onto the coast with a steep twisty mountain road up to civilisation in Canada. (I've been there on a cruise and up the WhitePass railway, spectacular scenery)

Customer service told him that Jeep were going to suspend sales of WK2 diesel into remote areas of AK. Don't know if they did.

Later that month he said he cancelled his order for a Dodge1500 deisel and was going to sell his JGC :(



There's a couple of other familiar names on that facebook list including "dixonf" and "Benno" to the rescue at the end there, pushing the software update. Seriously, Jeep should be paying him.
 
#686 ·
Thank you for your responses everyone. Will be keeping a keen eye out. Again, my service guy said (as I drove out yesterday after my flash update) I have to watch my stop/starts - my answer was even with my 'stop/starts' why wouldn't it of done a re-gen in my 8 return (16) trips 45min or more in length in the 7 weeks between limp mode then ? No real answer to that just for me to drive in manual mode around home. The Flash also rectified an air-conditioning issue and a cruise control issue (plus the ETC issue) - the other two I have not had any issues with. Samantha.
 
#687 ·
I would totally disregard everything they have told you. Since when do you have to alter your driving style/street/destination because of the vehicle you are driving. The vehicle obviously has something wrong, what that something is, is any body's guess. We had 1 limp mode, and forced regen, none since. We would be the ones most likely to have them as we predominantly only drive 5 minute trips. A tank gives my wife about 45 days of driving. We have had the regen in progress message twice, and twice it successfully completed the regen whilest traveling our normal routes in traffic. Its seems to me that the regen's seem to be a bit hit and miss.
 
#688 ·
Thanks to the info Steve posted I was able to get the DPF full value going in Torque :thumbsup:

Now just to get the regen status showing and I'll log this data for a few weeks to see what is going on.

I did a quick 10km round trip and my DPF full value increased by 2%.

Yes, you should. Actually I'm pretty sure that our service techs can do this already. The guy who seemed most switched on described going through a similar process before deciding to replace my DPF. It's often a question of how much they want to tell you, because I think they are all on damage control mode right now. A significant number (Maybe 10-15% of JGC WK2s MY 2014) have this fault, and I think it's giving them major strife.

I decided to leave the OBD Facile and Torque to those in the know. It involves getting an OBD Blue-tooth adapter. If I get more regen. problems, maybe I'll invest in one.

I'll be optimistic for now and believe that the last TSB has fixed it.

Actually in a recent "highway" drive, I was looking at the proportion of time that the tachometer was in the 1800-2000 rev range. It was really only on the hill sections, so there is not much opportunity for a normal regen if that's what it takes.

G'day all

I have a MY14 JGC purchased July 2013. I have had a perfect run with it (39,000 k) and have not had one problem till last Sunday when I experienced the dreaded DPF issue with accompanying "limp mode". The EVIC showed message FILTER 100% FULL and the car went into limp mode without warning.

A slow 40k trip to the dealer where the mandatory manual regen burn took place. i too got the usual dealer speel..."too many short runs.... or perhaps it could be poor fuel quality... have you been towing?.. that could cause it." As the result of closely following this thread, I took that advice with a grain of salt and to mean "we haven't got a clue why your car's DPF blocked up."

i have my suspicion that it is a softwear issue and put my experience out there for comment.

Two days earlier I had my auto sparkie fit an anderson plug and during that process he disconnected and removed the battery from the vehicle. after re-fitting the battery all systems worked with the exception of the PASSIVE ENTRY. I got a message on the EVIC requesting SERVICING OF THE PASSIVE ENTRY. The very next day I got the DPF 100% FULL and accompanying LIMP MODE MESSAGE.

Can anyone confirm or deny that removal of the battery may have caused a softwear glitch during re-boot of the computer?

Cheers Brian
 
#694 ·
Did your Auto Elec remove any plastic trims in the boot? If so, it is likely that he disconnected one of the passive entry receivers... and the error message purely pertained to this event.

Disconnecting the battery will have nil effect on the DPF system.

Cheers,
Steve
 
#695 ·
You got it in one for the passive entry Steve. Was sort of hoping the DPF issue might be related. Looks as if I join the frustrated DPF mob hoping for a solution. Kind of makes one feel very lucky having not long completed 10,000k towing in remote central oz. Id hate to see this come up at Cameron's Corner with a three tonne van hooked up.

Cheers Brian
