Regen Saga

Ok most nights when I pull my Jeep Ecodiesel in the garage after work the truck smells slightly warm but nothing abnormal, tonight I pulled it in the garage and it smelt extremely hot like metal melting under the vehicle. I assume(since the vehicle doesn't tell you) that it must've been either in the middle of regenerating, or just finished up a regen. This happens to me maybe (1) time a month give or take. Does anyone know the consequences of shutting these engines down anytime during a regen? Why would they not put a simple light on the dash that comes on during a regen? I would have no idea when this is happening. Any thoughts?

Re: Regen Saga

Don't stress it. It will warn you if it's in regen and you have to keep driving.

I concur with you that there's no reason to stress, but your statement about regen could be misleading.

There is no indication of a normal regen. These happen completely silently, and barring the use of an OBDII tool the only way to tell a normal regen is underway is the increased fuel consumption. If EVIC instructs you to keep driving then it is an abnormal "emergency" regen.

It is certainly plausible that chadg2's Jeep was mid-regen when he parked. If the smell really bothers you, then you can use the DPF regen mode PID for the Torque app—that will tell you for certain whether a regen is underway.

Re: Regen Saga

It will say DPF 80% full keep driving at Highway speeds. That doesn't seem like an emergency to me. It suggests that you continue to drive at Highway speeds. If you're going to work and shut it off, you're not going to get back in and drive around. You're not going to miss work either cause the car needs to regen. You just know that next time not to interrupt the regen.

Re: Regen Saga

If you were half way through a regen, then the filter would be cleaned out to 30%-40% capacity. It will kick off again when it gets up near 60-70%.

I agree Jeep should be providing an indication of when a regen is in progress, and a readout of how full it is would be very nice.

Maybe it will work that way, maybe not. I drove 600+ km at highway speeds last week with the DPF level reading 100% the entire time before the Jeep elected to do a regen, whereupon it burned down to 9.4%. I guess it didn't feel like it needed to regen before that time... there were no warnings, no messages to "continue driving", no MIL lights. It just didn't want to burn it off, even though it had hours of highway speed driving when it could have.

It's abnormal to see that message. I have never seen any such message, and most North American model EcoDiesel owners seem to see it once a year or less. As I said, normal regens are completely silent and occur every ~500 km or so.

The key point remains: don't stress about regens, especially on North American model EcoDiesels. The worst "problem" here is the smell in his garage.

I apologize if I seemed unfriendly. I was commenting more about not drawing parallels between the way export model EcoDiesels like yours deal with DPF regen vs. the way the NA models do.

For example, there have been essentially zero reports here of the insidious DPF limp mode issue that has plagued the export models. I have no clue why they would manage the DPF differently in your models; regardless, something is different.

No problem. Yes, we don't have the DEF, and it would seem the software behaves differently. I've heard some suggest their car started to regen as they were pulling into their driveway. When they started up the next day and the car came up to temp the regen started again.

So it will probably be one of those two scenarios, depending on how much had been burnt off prior to stopping the car.

I actually saw the "regen" message about 5 times last year, but it also seemed to coincide with my first (of several) P20EE errors. After I got the first one, I never saw that message again (August 14).

How do you do this? Does this option appear in the radio menu, or dash screen menu?
