I'm hopeful the filter will stop the frequent clogging issue but I still believe my Jeep has a problem with the auto regen system. Both times it has gone into "regeneration in progress" mode within one to two seconds the red throttle control system message has appeared and the car drops into limp mode.
Yes, that is why they released the TSB, it seems this changes the parameters of the regen conditions, from what I've heard. Of course it doesn't allow for faulty sensors or filters that won't clear despite a regen (that happens with all dpfs eventually).

I think Jeep know there is a problem, which is why they released the TSB, and why they tend to replace dpfs after the 2nd failure (if the service center ask them). There seem to be some service centers out there that refuse to look at TSBs or just prefer to remain ignorant.

I wouldn't put too much faith in what the service guy tells you about diesel testing. They wouldn't have a leg to stand on, if every other car works fine with diesel from a certain station, except the jeep then the problem is Jeeps.

Yep, and I have a suspicion that you could run one of these things on something not far off crude, and still get more than 500km out of it before the DPF calls "game over".

A good story the mechanic came up with though. Maybe he could write some novels

Cheers,
Steve

It's in the job criteria for jeep mechanics, "must have good creative story skills for coming up with reasons why they cannot fix a customers car".....

Benno did a great job maintaining a list of info early on, but it's harder going when all the details are not readily available. So tell us you're let down, p!ssed off, selling the biatch, etc... but please take a moment to chuck in all the back story for us too.

Ok.

For the full story, pls read the attached - to which I got no real response or action.
Build date, unsure but purchase date 12 July 2013.
1st regen early in the piece went fine, but nothing seen since.
Monday 10 Nov, screen message flashed up instantaneously but I missed what it said, then - see pictures.

Regards

Adrian

Angry Re: Is DPF issue for 2014 CRD fixed now?

After lurking on this thread for the last 24hrs, I thought I should add my data to the mix.

I'm now part of the group as well.

I have a GC Laredo, 11/13 MY14 Build, and we have had the exciting experience of a Full DPF Filter, and Limp Mode. The car was at 14786 Km, and we had only purchased the car on Apr 2 2014.

We will normally drive to Busselton from Perth (nearly 3 hrs) every 6 weeks, and I drive on our Freeway at least once a week for 20mins (at 100 to 110 km/h)

We had just arrived back - last week - from a trip to Albany (5 hrs). So lots of opportunity to "drive at highway speeds"

Other than that it's school drop offs, kids training sessions, work and home.

I have never seen any reference to 'Regen' in progress. First think I saw yesterday was the "Exhaust Filter 100% full please drive at highway speeds", followed 5 secs later by, red thunder bolt, and the car stuck in 3rd.

Quick call to Waneroo Jeep where the car was purchased from, and everyone acted dumb about what the problem could be, and said ring road side assist. Rang them, and within 30 secs......" so sorry Mamme, we'll be sending a tow truck for the vehicle".

The car was towed to Osborne park (I know a couple of people have been there reading the thread), as it was 5.30 - they just tucked it in bed for the night and looked at it today.

Received a call this afternoon to say, yes all fixed - the filter was full and it's all be cleaned out. No talk about a 'Manual Regen" etc., just it's been cleaned out.

As I hadn't done the crash course in this DPF issue until this evening, I asked the question, "so why did this happen?" Received the answer, Oh as a mum, you do loads of stop / start / short distance trips which is not very good at all for the Jeep, so it is inevitable that this type of thing would happen and more likely will happen again. 5 minutes on this forum told me I should of run for the hills as I was being hit with quite alot of the smelly stuff.

There answer/remedy was/is make sure you warm the car up for at least 5 mins before you drive off - need to get the temp up of the engine so that it can burn the fuel off. Yeah right, I can see that happening every morning with 12yr old twins, and rushing them to different schools............."just a minute kids, we just have to warm up mummy's very new car, just so that it doesn't break down." My Volvo V70, didn't need this even in it's 13th year of life!!!!!

Or...........the other option was that I could buy $90 DPF Additive????, and add in 1/2 now, then the other 1/2 after 500km.

I then asked could I get this checked at every service - both the service admin guy, and who I think was the Service Manager, looked blankly at me, and said "we'd have to see what could be done - not sure"

Don't shoot me about the additive info - this is the interpretation I took away from my 15mins with them.

So I get home, ring my dear brother who is the ultimate rev head - builds race cars, and owns the odd diesel SUV. And he said something very simple.......which made me want to slap my forehead........."it's ridiculous that they want you to do things to your car, just so that it works properly and doesn't break down. You shouldn't have to alter your driving for it to work".

He is now going to ring around a couple of mechanics he knows that work for Chrysler/Jeep and try and get the inside story.

He did say that he'd heard of the issue before we bought the car, though thought that a fix had come through for it. He drives BMW's, so hasn't had an issue. His Father In-law has a GC I think MY13 build, and has never had an issue.

OK, war & peace over...........I just wanted to add my 10c to the mix.

Would be interested to hear your thoughts on my conversations with Jeep.

Re: Is DPF issue for 2014 CRD fixed now?

Great detailed report GMC. Because Benno had been slacking off with his list ;-) I will just have a guess that your car might actually be the "newest" to have this problem. Not sure of that, but it's certainly among them. Obviously the further this problem progresses through build dates the worse it is for the owner base in general. I'd definitely like to be "in the clear", but this is starting to look unlikely.

I'm sure that it's not just me who loves hearing the spin they weave at the dealerships. I enjoyed their assumption that as a female you only do short trips, despite your odometer readings suggesting otherwise.

I've previously mentioned that Ozzy Park are pushing a Fortron diesel treatment... they should be ashamed of themselves. It's good you have technical support... many don't and probably eat that story up.

It'd be very interesting if your brother can extract some truths from the Jeep mechanics about this subject. You can see by what you've read that solid information is very thin on the ground. Either Jeep have established a "cone of silence"... or perhaps just a sphere of stupidity and ignorance.

Cheers,
Steve

Right then, that is the point I would have slapped someone, twice, hard.
They just told you that not having the engine under stress is what caused the problem, damn you and your little mummy runs, doing only 14,786km in 7 months. Then asked you to have the car sit around doing nothing for 5mins before you drive it. This would simply exacerbate the problem, they’re morons and don’t seem to realise they just contradicted themselves.

Did you have it serviced at 10,000km?

Re: Is DPF issue for 2014 CRD fixed now?

Yes, as snuke says, letting your car idle for 5 mins is actually the opposite of what you want to happen. Because running at idle means lower combustion temps, which means more soot. The actual recommendation is to avoid excessive idling. Better to get in it and drive it if you want it to warm up.

And if you are doing lots of highway driving, then the regen process should be working. It seems that despite driving at highway speeds, sometimes it doesn't work for some unknown reason. I think it may be the computer thinking something isn't right (sensor inputs?), so it doesn't trigger the regen.

You should ask them to apply the TSB for this issue, which modifies the computer behaviour. As far as I can tell it seems to help:
