Re: Is DPF issue for 2014 CRD fixed now?

The TSB does mention lots of codes, I haven't heard of anyone actually being told what codes have been thrown.

http://www.wk2jeeps.com/tsb/tsb_wk2_1801814.pdf

Normally it is a 30min job to burn off the filter. In Oz this is such a common problem that the dealers sort them very quickly. There seem to have been a small number where the dpf burn didn't clear the filter, and Jeep have replaced the filter under warranty, that takes a few days/weeks.

It's same same old BS. The Dealer said that my vin didn't fall into that TSB.

I'm almost to the point where I have to rent a moving truck with an auto carrier to drag this thing back to where I live. Jeep is so incredibly slow fixing things, I can't sit down here in this little town and ignore my job. Nothing like throwing $1000 down the drain for a truck/carrier rental.

I've always thought about what do people do that are on long trips away from home when their vehicle breaks down. Do they sit there and wait until it is fixed? Do they tow the vehicle back with them? Do they head back home in a rental car and ship the vehicle back?

I could see these problems with a major issue. I am stranded over a freaking trivial EXHAUST FILTER.

How long did it take your dealer to do the regen? Did they say anything about any other codes? Talk about making a mountain out of a molehill this is crazy.
No point in driving it into a lake, because the dpf burn will never happen if you do that.

They understand it is your car donít they? Your property to do as you please. If you want them to do such and such and it wonít put them liable for warranty action, then I would bloody tell them that no is an unacceptable response, do it, do it now so I can drive home.
Supply you with the codes so your local dealer can look into it without it costing you money.

That was the line given to one of our local owners here too, but then the story changed to 'or if you have had the problem'. The TSB even says this: "If the vehicle is included on the RRT VIN list or if the technician finds the DTC, perform theRepair Procedure.

In any case, they should atleast perform the manual regen and let you be on your way. Is there no other Jeep service center nearby?

Re: Is DPF issue for 2014 CRD fixed now?

I think part of the problem for the US guys is that the service centers are unfamiliar with diesels, so when one comes in they don't know what to do....

Ya, the guy seemed more concerned about Chrysler paying him than getting the problem fixed. He said Chrysler wanted him to "look into" all of the other PCM codes which are obviously just after affects of the filter full. In two days I think the only thing they have accomplished is reading the PCM codes.

Thanks for pointing out the "if you have the DTC" part. I will show that to the dealer. I think all they do is put a VIN in and see if the computer spits a response back. There is another Jeep dealer, but it's ~35 miles away. So either I take two hours and limp it over there and possibly risk compacting the soot even more, or tow it.

Jeep dealers are clueless about everything, not just diesels. They have a pretty bad rep in the US for a reason. This service manager seems like a real "by the book" block-head, went on to mention it may be next week until they can "resolve" the issue. Like sitting around out of state and not showing up to you your job so that a dealer can tinker with an exhaust filter is no big issue. So I may end up towing this thing 600 miles back home.

Might be worth ringing a few close by and see if they are familiar with the problem and have fixed it before. If yes, then tow it over.... my 2c.

Good luck, hope this never happens to me.

Re: Is DPF issue for 2014 CRD fixed now?

There is a good video here:
Understanding Diesel DPF Regeneration - YouTube

(It's NOT Jeep specific.)
On how these things work. Many other makes have them WITHOUT problems.
It also explains why good oil, changed regularly, is essential.

I can't help feeling that if people are having problems, then Jeep need to do a lot more work on software, and possibly hardware.

Re: Is DPF issue for 2014 CRD fixed now?

Interesting. It looks like the Jeep uses a differential pressure system based on what I've seen. I'd have to question his statement that 25-30% fuel economy loss just do to the DPF system. That's quite a large amount.

Another question is, is the JGC dumping fuel on the exhaust stroke or does it have a fuel injector in front of the filter?

Re: Is DPF issue for 2014 CRD fixed now?

I understand it is on the exhaust stroke. There is a reference to this in the diesel manual talking about oil levels rising after a dpf.
Quote:
It is possible for your oil level to be slightly
higher than a previous check. This would be due to diesel
fuel that may temporarily be in the crankcase due to
operation of the diesel particulate filter regeneration
strategy. This fuel will evaporate out under normal
operation.
It also dumps some EGR gas into the exhaust to help oxidisation....

So he talks about different types of regeneration systems. The VW uses a passive system. I know the jeep does also, but does anyone know if its simmilar or same as the VW design? The VW design doesn't require the extra injection of diesel into the exhaust as the DPF is so close to the manifold that as soon as you hit highway speed it automatically burns off....
Sounds similar to what the jeep is supposed to do, but does anyone have info on the Jeep exhaust system?
