Good question. How many hours were you off-roading? As that can give us some idea of how long we can go before getting an EVIC alert.

The obvious question is how much time, on average, do we have from the first EVIC message to limp mode. Jeep could answer that possibly--though Jeep would likely give you some "it varies widely based on ........" kind of answer.

I would make sure I had put in some highway time immediately prior to going wheeling to ensure starting out with a clean DPF.

So this message - Exhaust Filter XX% Full Safely Drive at Highway

- comes on, and at the same time our cars are put into limp mode, locking it to 4th gear and restricting revs.

Car after car is having to be towed back to dealers because of this stupid programming fault.
Owners are given no guide that this may even happen, or why it happens in our paperwork.
Hi Snuke, I'm having the exact same problem as you have described above. Happened to me last night.

Got exactly the same problem as well and it happened today for the second time in 4000km's. No warning message, no regen warnings, nothing. I've heard some people say the regen message only occurs if you have it in a particular dash mode but that seems dumb.

Getting really annoyed about this happening for the second time in two months. It seems utterly ridiculous. If a regen is required, then pop the message up and leave it up. Sending the vehicle into limp mode is the dumbest thing possible because how the *#(^# are you supposed to regen in limp mode.

The car is perfect otherwise, but this little thing is going to result in some nasty emails with Jeep.

That is not correct, it will appear no matter what setting you have the EVIC on.

Re: exhaust system regeneration process

Just for the record, when it tells you, you need to regen and drive to clear it... how far and long do you need to drive before cycle is complete? 5-10 miles? 15 min? or an hour ?? it would be good to know roughly if someone knows....

Must DPF regeneration occur at highway speeds? Or can you do it by revving it in neutral for a while?

Consider that at 55 mph in high gear on a highway the engine is not at a high RPM. The diesel supplement says "simply driving your vehicle at highway speeds for up to 20 minutes" will perform the regen. My guess is that what is needed is not idling for up to 20 minutes straight. It is not clear if higher rev's help.

The supplement says the particle filter problem is caused by "exclusive short duration and low speed driving". I suppose that i am okay if I avoid that scenario before going off-road.

No, it seems you have to be at speed (most dpfs require above 64kph). Though if you get it done by the service center they can trigger a regen while standing still with their diag tools, and it brings the revs up over 2500rpm.

I think the reason for the car moving is to avoid smelly gases and the heat affecting anything around the car. Apparently it really cooks whatever is under your car if standing still. Do it over some dry grass and you could start a fire.....

Generally 15-20mins, the message on the screen should show you the progress, it will say 80%, then 70%, 60%, etc.

Yes, it would be good to put some pressure on Jeep about this. It is really killing the reliability of the diesel.

The thread we are tracking this issue in for aussies is here:

Is DPF issue for 2014 CRD fixed now?

We've tried to collate some data on the cars experiencing the problems, so far seems to be limited to April-July 2013 builds.

I knew there had to be a way to invoke regen manually. Although your point about temperature is well taken. Stationary regen in the backcountry does not sound like a good idea.

Hi all, I'm considering getting a 2014 GC Ecodiesel, and I googled dpf regeneration and it brought me to this thread. So I registered and here I am! lol! I have a 2013 Passat TDI, regeneration interruptions are a concern as well. In the Passat we dont have any message displaying like you all do in your GC's, but I use a scangauge and monitor diff. EGT's to inform me of a re-gen in progress.

But my question to you folks that say, its ok if you interrupt a re-gen in the GC's, and it will start again once you start driving the vehicle again. Don't you all have a concern of extremely high turbo temps during re-gens and possibly oil coking in the turbo? I'm new to diesels and especially to Jeeps, but maybe there is a new process or procedure this Ecodiesel engine has that my TDI doesn't.

I'll be trolling this forum for sometime until I can make myself pull the trigger and buy an Ecodiesel! lol!
