As it says "may display". I am not sure on the logic behind that, it should always show.

It doesn't matter what screen you are on, if it is going to show, it shows.

Re: exhaust system regeneration process

OK. Here's what we know about the NAFTA version of the diesel:

1. The EVIC doesn't show a message during the normal regen process that we know is happening based on 1200F EGTs we are seeing.

2. It has been verified that owners who drive too much in slow speed city conditions ARE seeing a regen warning. This is a final warning to allow a regen immediately. Most NAFTA Jeep owners will never see this.

Re: exhaust system regeneration process

Correct. That is not just a NAFTA thing, that is the worldwide process.

Re: exhaust system regeneration process

UPDATE

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.

Re: exhaust system regeneration process

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.

Re: exhaust system regeneration process

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.

Re: exhaust system regeneration process

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.

Re: exhaust system regeneration process

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.

Re: exhaust system regeneration process

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.

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.

Re: exhaust system regeneration process

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:

http://www.wk2jeeps.com/tsb/tsb_wk2_1801814c.pdf

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.
