Re: exhaust system regeneration process

Yes the Australian models are different. The fault comes up with "blocked exhaust , drive at highway speeds" and then puts car into limp mode at the same time !!!.
Seems the different models share enough computer software to confuse themselves about whats happening. Mine has been fine for 5000k now, still waiting for recall four about the steering computer upsetting the abs computer… Licence plate "Recall" staying on….Paul

Re: exhaust system regeneration process

I have 39,543 miles and never before got this, until yesterday. I've always done a little highway driving each tankful, but then for about 1+ tankfuls I did only in town, local driving.

I took pictures as I got the messages. I won't include them but they captured the mileage and messages. It took 25 miles to clear.

I am in the USA - CA near San Francisco.

39,543: Exhaust System Regeneration in Process Continue Driving (while driving to errand)
39,546: Exhaust System Regeneration in Process Continue Driving (after errand, on restart, so I went driving)
39,549: Exhaust Filter Nearing Full Safely Drive at Highway Speeds to Remedy (drove onto the highway)
39,550: Exhaust System Regeneration in Process Continue Driving
39,556: Exhaust Filter Nearing Full Safely Drive at Highway Speeds to Remedy
39,557: Exhaust System Regeneration in Process Continue Driving
39,568: Exhaust System Regeneration in Process Continue Driving (arrived at destination, parked, engine off)
39,568: (on restart; no more messages)

I wouldn't have turned off your Jeep lol. That message appears on stock vehicles when the filter approaches 80%. It normally doesn't have to because the passive regenerations occur at 65%. If the passive ones get interrupted enough, the message appears as it approaches 80%.

That's expected. A normal full regen will burn the DPF down to 8 or 9% full. The "ZOMG! Regen Emergency!!1!" alert on evic pops up at 80+% full. The prompts were coaching you to drive until the regen was complete. Your regen wasn't total, though it was sufficient to bring the DPF well below the alert threshold. Thus the warning is gone.

tl;dr: no message == you're fine.

You are referring to silent, active regenerations, not "passive". Passive regens are what happens when exhaust temps are high enough to burn off soot without adding any fuel (n.b. adding fuel is what makes an "active" regen). Passive regens very rarely happen... think "towing in high gear" type scenarios. All other regens are active, though the EVIC only displays regen status if it is an "emergency" type active regen.

Re: exhaust system regeneration process

Im sitting at home having just put my Jgc 2014 on a tilt tray after 33680km of trouble free driving, no warning just came up with the drive at freeway speeds and it promptly slowed to 60km/hr and 3rd gear. My foot flat to the boards locked in 3rd... Misses is realy pissed and i cant blame her, i love the car but hate the feeling of living 50km from the only dealer in cairns, my family is now stuck with no wheels and im sure im not the only one... come on Jeep! Fix this shit once and forever...

THIS. This is why last weekend we traded in my beloved SFU for our first-ever minivan. Having to tow a JEEP TWICE in 2 years because of exhaust treatment issues caused a complete loss of faith, and my wife wouldn't drive it without me.

Between this, the RAM issues, and VW, I'm not so sure we 'Mericans will have passenger Diesel options much longer...

Re: exhaust system regeneration process

Once my 10 years / 120 miles extended service contract is up will be going with a tune that doesn't cause this issue. I have zero issues with the problem identified here but the fact you are held hostage to a regen is less than stellar engineering...

Re: exhaust system regeneration process

Having similar issues with the DPF Regeneration issues here in Alberta, Canada. I am new to a diesel and have been getting 'educated' over the past week on the DPF since I unfortunately discovered what happens when it gets 100% clogged and goes into limp mode. I have less than 5000km and probably regen'd about 5 times. I do alot of short distance driving so understand that likely is the cause of so many regens. I was at first surprised that the dealership never informed me of this requirement as it is rather an important one! But once I talked to the Dodge service techs I started to understand why, they really do not know anymore than me since the DPF regen is not that common here...yet, everyone seems to be mis-imformed or not imformed at all.

My worry is when I start towing, do some offroading in the middle of nowhere, and if we have a very cold winter. I see this as potentially causing me some serious grief!

Can anyone tell me any ways to be proactive to avoid the excessive regen or clogging prematurely....
1. Dont idle for long periods (OK...may be difficult in winter months)
2. Regen ASAP when the first warning comes up (OK...depends if I am able since I have to hit 80km/hr for the regen to work)
3. Use quality (correct) oil and regular oil changes (OK)
4. Use higher cetane rated diesel such as Shell V-Power (????)
5. Use additives especially in colder winter months (????)
6. Any other mechanical parts that I should service more frequently than the dealer or manufacturer for that matter knows about?
7. Bypass or Delete the DPF ....just wanted to throw that in since it would be my first choice...maybe after warranty is up!

Apologies if this has been discussed, new to the site. Just want to avoid ever experiencing the limp mode again!

Buy the GDE hot tune (warranty caveats apply), use decent, normal diesel, and be done. With the GDE tune the regen period is much longer due to improved combustion and EGR is disabled, among other improvements.

As GDE said elsewhere, 'Regarding the DPF, with our tune you should be able to idle for roughly 58hrs consecutively before the "Exhaust Filter 90% Full Please Drive on Highway" message appears in the cluster. At that point, you can just press the accelerator pedal to the floor with the engine at its 2500rpm governed speed and the regeneration will start and run no problem.'

...meaning you could even do a regen while parked if you really needed to.

http://www.greendieselengineering.co...oDiesel.action

Note that GDE offers a "high idle" option if you plan to idle during winter months and want your diesel engine to remain warm. Stock doesn't do that.

Also, when you say you've had five regens, do you mean you've had five "ZOMG emergency regen!" episodes? Normal regens happen without any message showing up on EVIC... they're "silent". If you've seen the "drive at highway speeds" message 5x then that's abnormal even for short hop driving. I mostly do short hop, in city driving and I've never seen an "emergency regen" message.

The way I know whether I'm in regen is via OBDII data.

Re: exhaust system regeneration process

Roadkill, thanks for the reply. The five regens were messages that come up on the EVIC basically saying to "Regeneration in Process Safely Drive at Highway Speeds to Remedy" or something along those lines (sorry cant remember the exact wording).

Basically what I have to do is jump on the nearest highway and get it up to 80km/hr (for regen to kick in) for upwards of 10 minutes or more which is quite a nuisance since I have to drive away from my city and drive back. If it were every 2-3000km it wouldnt be so bad but basically almost every tank of diesel I am regen'ing.

The last time it went into normal regen mode unfortunately I was unaware and uneducated what would happen if I didnt clear it, next day I went into limp mode and had to take it back to the dealer for a forced burn.

The DPF delete kit or retuning is definitely not an option for until I am past warranty, just too expensive of a vehicle for me to tinker with right now, especially when everything is run by damn computers nowadays, fixing something with just a wrench is out of the question.

So I think I will try the V-Power for now, idle less, and take out for a highway race when it says to regen. The diesel additives I may try but not until we get into winter months.

I just wanted to reiterate that if you saw any sort of message about a regen, the filter being x% full, or driving at highway speeds, then that by definition is *not* a normal regen. It's the "emergency" type.

Understandable. Reread that feature list for the tune, though, and think about how you could have high idle while you're sitting in that cold, idling diesel this winter (haha). Also, realize that the GDE tune would make your engine last longer than if you run stock, since it sounds like you're planning to keep it past warranty anyway.

Best of luck, welcome to the forum, and let us know how it goes.
