My 2014 diesel gc has gone thru the exhaust system regeneration process at least twice and i have less than 1500 miles on the car. Is that a normal interval?
Both times i have been able to continue driving like the Evic message says to do but what happens if someday i am in a position where i have to park and shut off the engine while the regeneration process is going on. Is it bad for the car?
It would appear that the Oil Life Counter is a CRITICAL COMPONENT to regen. The techs could not find anything wrong with my jeep, other than the fact that the counter wasn't reset 2 weeks ago. This triggered a CEL after about a week (they didn't get into whether or not it is mileage based), and it then refused to regen.
This SHOULD be in big neon letters in the user manual...but it's not.
They did a regen in the shop, and everything looked good and checked out.
2 days ago I received the warning message stating that the filter was almost full, and I needed to drive at highway speeds to remedy. I did as it said and nothing happened. All of a sudden I went into limp mode. I drove straight to the dealership and luckly before they closed, they helped me out and did a manual regen with their diagnostic set. Everything seemed good to go until I got the warning message again today. This time I made sure to ensure I adhered to the required parameters in order to start the regen process carefully. I drove my Jeep for about an hour at 65 mph and it never went into regen mode. I made sure the oil life was reset also, even though I hadn't changed the oil yet, and there was over 3/4 of a tank of fuel in her. I don't know what is going on with my jeep but she is not cooperating with me. Am I doing something wrong?
Don’t do that again.
It should be reset only when the oil is changed, and as mentioned earlier it is critical it is done when changed. It is also equally critical you don’t reset it until it has changed. You have told the system it has new oil in and should be treated as such, so in better condition with less contaminates than your oil really has. It won’t do the passive regens as frequently as it would / should if it was still aware that oil was in fact older and in poorer condition than it thought.
We have cases in Aus where it has gone into limp mode only a couple of hundred miles after purchase, so not oil related, not fuel related. The thinking is that it is pre-delivery related. Most likely spending too long idling. Some DPFs are just not right, like any part, some will be faulty.
We'll here is my experience with the regen process. I got the oil change required message. Had to wait two days before I could perform the change due to work schedule. During this time the check engine light came on and the code read "degraded oil viscosity". I changed the oil using a Chrysler filter and the synthetic oil recommended by the dealer. I tried to reset the oil change message but it would not reset. Perhaps due to the check engine light. Called the dealership and was told to drive the car and the check engine light would clear due to the oil change. That never happened. Then I got the regen message to drive at highway speeds. So I hit the highway and 50 miles later still no message that regen had taken place. Then I got the message that the filter was full and an additional message that the throttle position sensor was whacked. Then the car went into limp mode. 50 miles from home. Mind you this was on a Friday evening around 9:00 pm. Called Chrysler roadside assistance and was trailered home. Going to the dealership tomorrow.
I have a 2014 JGC Summit diesel and I live in a small town in SE Alaska where driving at regeneration speeds is not practical. The vehicle has now been towed to Whitehorse, YT and has been at the dealer for one week.
I would not buy a diesel Jeep unless you can drive it regularly at highway speeds and in my case I would not buy a diesel Jeep period. I intend to sell it and buy something more reliable.

It’s not a Jeep thing, or a VM Motori thing, it is a DPF thing. Purchasing any diesel vehicle with a DPF is not a good idea if all it gets is short run/low stress use. In Aus and Europe there are ton of smaller passenger cars that have constant issues because the driving style is not suitable for DPFs. It is an education thing, and a big part of that is dealer education and clarifying with the consumer the conditions the car will be driven in.
Our JGC Diesel engines are very reliable, as are most modern diesels. You just happened to buy a vehicle that did not suit YOUR particular purpose.
Sorry that it didn't work out for you......they are great cars.
I guess "reliable" is a relative term. I did drive for over 30 minutes at highway speeds and the vehicle did not regenerate. I wouldn't call a vehicle that is made, at least partly, for going off road reliable if it can't be driven at 4-wheeling speed for any length of time.
You should only need a 30 min drive once a month at highway speed to keep the filter clear. I use any excuse to go for a drive in mine!
The dealer should be able to force a regen in 30 mins, although if there is a fault with the DPF, then they may need to replace it. This has been required for a few aussie owners.
If it isn't regenerating despite driving it at highway speeds, then the dpf may have a defect, or the computer isn't performing the regen for some reason. We had quite a few of these problems in Australia (since we buy so many of the diesels, we saw this issue come up a lot), it seemed to affect certain build dates more than others too.
There was a TSB to fix the regen issue, but it still seems some dpfs had defects and had to be replaced.
It is worth getting the dealer to check for these error codes, and getting them to apply the update if they exist:
If they perform a manual regeneration and apply the update, and the dpf still blocks up despite driving at highway speeds once a month, then they may need to replace the dpf.
Driving offroad is not inhibited by the regeneration process, many diesel drivers do plenty of off road driving without the dpf clogging. You are actually more likely to get the high exhaust temps required to clear the dpf while driving offroad.
Okay sure, it is a Jeep thing, I missed a word, it should have been “not JUST a Jeep thing”. Speak to the thousands and thousands of Mazda, Subaru, Opel (GM), VW, Mitsubishi and more owners that have had their DPF bring them to a stop. It is a DPF thing, they are horrid for short distance driving. Selective Catalytic Reduction apparently is a far better system in this regard. You guys in Nth Merica have a weird situation of getting a DPF with part of a SCR system.
Subaru put this on their website
“So again it is clear that a diesel engine vehicle requires a driving style and method of use that is only suitable for longer distances and higher loads! If this is your particular method of use and you travel high kilometres then a diesel engine vehicle is particularly suitable due to the fuel efficiency and environmental performance. But if you normally travel short distances then a petrol engine is a better choice.”
Definately agree that this is not just a Jeep issue, but a DPF issue. I did get the DPF almost full message for the first time after about 7500 miles on the car. I was surprised because my wife had just returned from an all highway 400 mile trip three days prior to getting the message. I took it on the highway and it immediately went through the regen process - I monitored it on my OBDII scanner. The message dissappeared as soon as the regen was completed and everything was fine. I was just curious why we would get that message after driving on the highway just a few days before. We have been doing mostly driving around town and have never had that message before.
By the way I love the diesel and have not had a single issue since we have owned the car.
It is good to hear that some JGC diesels are regenerating as designed. Mine is not and from what I can tell by looking at a variety of forums, nether are quite a few others.
Yes, as soon as I got on the highway the exhaust temperature started to rapidly rise. It went to about 1220 °F for about 10 minutes and then fell rapidly back off to about 600 °F. As soon as the temperature dropped back down the message on the EVIC went away. It actually started trying to regen before I got to the highway at lower speeds but it would not get above about 900 °F in stop and go traffic. This is the same pattern I have ssen a couple of times before on the OBDII scanner (but those times I just happened to catch it with no EVIC message).
Mine has regened properly for 18k miles. I never got an EVIC message but ODB2 monitoring revealed that it regened every 130 to 180 miles depending on driving conditions. Something recently failed in the DEF (SCR) system and off to the shop it went. Tje EVIC basically said "bad DEF, 200 miles until engine won't start" I should be getting it back this week.
I did have a bad tank of "dirty" fuel once and it regened more often until I refueled. I had to make sure I didn't idle or stop and go much during that time.
They'll go into regeneration at less than highway speeds only if there aren't long stops. My commute to the bus terminal is about six miles of 30-40mph continuous roads with only three lights. It will complete a regen if I drive around for a couple more miles after getting home. I drive until CAT1 gets below 1,000 degrees as viewed on Torque.
Believe it or not, you can keep it in regen at any speed including dead still if you can hold RPMs around 1500-1800. That's easier said than done as the turbo makes the motor try to run away. It takes extreme concentration and driving technique using the paddle shifters and going to neutral while braking to a stop light.
What is the procedure to do a manual, stationary regen?
I would like to go camp in some remote location and explore the roads over several days. That will be many hours of driving without highway speeds. I am concerned that I will get into a regen problem.
So I heard from the case worker about the issue. She said there is no known flash to correct the problem and that Jeep was going to block sales of diesel Jeeps to rural areas of Alaska. For the record she doesn't seem to have a clue but I have a vehicle that hasn't regenerated since I received it back from the dealer and driving it is like waiting for the other shoe to drop. My Jeep has been out of service at the dealership 10 days total in 4,294 miles or one hour for every 18 miles driven. I cancelled an order of a new Dodge 1500 diesel and I will be selling my JGC.
I have just had this happen twice in 2 days, updated software etc, 400ks later back in limp mode, redone and waiting to see how long it goes this time ( all highway driving as well)
I have 7200 miles on my Summit and never saw this message until two weeks ago after I put fuel in from a station that I normally don't use. Now I've seen it twice. The first time I had to stop before the message cleared (was heading into work). A few hours later when I started the vehicle the message had cleared. The following week I received the message again and immediately took the vehicle on a short highway run at 70mph . After about 10-15mins received a message that Regen process was completed. I've never seen the message that others have reported saying "Drive at Highway Speeds etc..."
Is it possible it could be from a 'questionable' tank of fuel? I normally drive 140 mile (RT) every weekend at ~70-75mph so I would think it should have plenty of time to regen on its own.
I had done 22,000km mostly all highway and towing my van and the light came on for the first time and said 80percent full and was regenerating or similar and after about 20kms and went off and said it was cleaned. Next time I drove it after about 10kms it came on again but this time said 100 percent full and went into limp mode. Sent to dealer on tilt tray (130KM) they upgraded software and done manual clean and all ok. Went less than 400km light came on again and again went on tilt truck to a different dealer as we were heading north with caravan. They have done the same procedure but cant guarantee all is well. My concern is when we head off on our next trip through central Aus is that if it happens we are 1000km from a dealer. I would like to know how to do this manual regen with the computer.
I suggest you have the DPF replaced. If its not responding to the forced Regeneration then there must be something wrong with it. That said, it could also be that the ECU for whatever reason isn't going into regeneration mode properly.
Oil temp should not change appreciably. The heat is mostly generated by burning fuel inside the DPF rather than in the engine. You'll find that EGT is actually several hundred degrees less than DPF temp during a regen.
Same observation here. All the heat is downstream. If anything, the diesel injected during the exhaust stroke doesn't ignite and should cool the cylenders.
Now the rest of the story... Driving 700 miles (over 500 towing) after getting the regen in progress message I got error P202E (grrrrrrrr). The error stayed on towing 500 miles back home. I need to get the flash in the famous TSB: 18-018-14 REV. C
At 7500 miles I got the regen message. I completed the regen and at 8000 miles, on the same trip it got the maintain highway speed. I maintained 80 MPH for 2 hours and the message never went away. I stopped for fuel and it went right into limp mode. Had to drive for 3 hours to get back into civilization, out in the middle of Nevada desert, where I could get towed. They did a manual regen and so far it is OK. It had the upgraded flash. They could find no reason for the filling of the DPF.
I've got the regen message twice. Once at 24 miles. Brand new off the lot. And once around 7400 miles. Both cleared and completed. At 17500 miles with no problems.

My GC has had the exhaust filter message come on twice,saying to drive at highway speeds, but with limp mode you can drive for hundreds of kilometres and does no good.
I live in Australia but have never had any warnings about this problem, The first time it came on was a few weeks after towing my van to Queensland, should have blown out any accumulated particles, any advice ?
The Australian system is different to the USA system but apparently based on the US one not like the earlier systems in the MY13 models which were built in
Europe. Fiat Chrysler Australia has released a software update - released in Australia on the 19 the December that they assure will fix this problem - however they are not issuing it as a recall but they will apply it if the vehicle is towed into a dealer or at your next service. So those without this upgrade can sit on their time bomb and hope it doesn't go off before the next service at a dealer.
Mines done this three times; last at 8900. Stuck in limp mode; lights on dash and filter blocked message. Dealer replaced exhaust temp sensor last time and it not working again or the Computer and it are not talking.
Jeep in dealers for two weeks now with a promise to repair by mid jan...bec part coming from USA.
Whether this will fix it is next issue
So im staying home this holidays....
