Well said. I think the service departments are overwhelmed with the popularity of this vehicle and it's issues. People have different uses for this vehicle however and therfore some reluctance by the service departments to do some of the updates unless requested as they are finding that some of the updates are impacting on other systems in the vehicle (lack of research but who knows). Like the latest transmission update, didn't let them do it as mines smooth now and changes well when towing and didn't want the different shift points suggested.

Winter summer additives ect.
I've booked mine in to have that update done tomorrow.
It's 18-019-14 rev A but Jeep Aus have it referenced as RRT 14-104 (rapid response transmittal) and can be done under warranty.

My issue is the rattle or knocking noise under acceleration which has developed worse in the last 2 tanks of fuel (both Vortex diesel) after about 2500 km total. - there's a separate thread on that.

I haven't experienced the DPF problem, but if the update cures that too then great!

It can take Jeep a while, but they do seem to get there in the end with these issues.

Re: Is DPF issue for 2014 CRD fixed now?

I also asked about a regen said I have never seen one happen, their reply was along the lines that u obviously drive it like it was designed for? Don't know what that means.

Is DPF issue for 2014 CRD fixed now?

No they told me the rattle fix is not permanent and only lasts a few days, no permanent fix for that one yet, mine isn't that bad anyhow.

Re: Is DPF issue for 2014 CRD fixed now?

X-posted with the "Diesel" rattle thread

I had this update RRT 14-104 (TSB 18-019-14A) done this morning , not as part of a regular service. Done under warranty.

This was for the addressing the detonation/rattle noise at low revs under acceleration developed in the last 1000km or so.


Service guy said that it adjusts the injection sequence for the fuel which stops the injector/knocking noise
(I guess that would be adjusting the timing to cope with different diesels)

He also said that some earlier updates for this issue only lasted a short time but this one SHOULD fix it properly.

Time will tell but it ran sweet and smooth in the 25k back to the office. Can barely hear the injectors noise at all.



He didn't tell me much about the DPF update in this TSB

I haven't had any DPF problems at all but the update is supposed to be a fix for that issue as others have said.

Done 3500km so far in just over 1 mth on Vortex
1200km urban driving
1000km highway unladen - 7.1L/100km
1000km highway towing (1900kg) -12.0L/100k
300km winding country road/dirt (Coffs Harbour/Bellingen/Dorrigo)

Re: Is DPF issue for 2014 CRD fixed now?

Has anyone tried using the Penrite Enviro+ DPF cleaner product. Their product sheet seems to indicate that it should help reduce soot accumulation in the DPF as well as clean the DPF. They also claim that it can improve fuel ecconomy. Apparently has been tested on suburban buses with DPF filters. They claim that it reduces the temperature at which the soot is burned in the DPF. For those discussing the safety of the regeneration process whilst stopped roadside they claim it can reduce the production of flames from the exhaust during the regen process.

I have been looking for some info on the product on the net and on other forums and found one on a Pajero forum where one of the members had used it and it reduced engine noise and improved fuel economy.

After many months of working extremely hard to convince the "hugs & kisses" that the 2014 (or 2015) Jeep Grand Cherokee WILL be much more reliable than our previous 2000 WJ-Limited V8, I'd hate for the DPF issue to crop up with the new JGC.

If the DPF Limp Mode happens to my wife while I'm working interstate, it will not be pretty, and I will be in more trouble than Ned Kelly

To be safe should I go with the HEMI? Apart from a higher fuel usage rate, it isn't hampered by the "apparent" CRD's DPF problem.

Any comments, recommendations or reassurances are greatly appreciated.

Cheers,

Marty
Well nearly 12 months on and 550 posts later and it appears that while there are many that don't have the dreaded "limp mode" DPF problem, there are still some that do.

Not sure if I'm willing to take that chance with the Diesel at the moment, but in reality I won't be buying a Grand Cherokee until the new model emerges in 2017, so hopefully this Limp Mode problem will be a thing of the past by then.

Thank you one and all for all of your most welcomed responses to my initial question. I love JeepGarage and all the positive contributors within it

I'll post picks of my new 2017 Grand Cherokee Overland in a few years time. Only time will tell to see if it'll be a Diesel or Petrol model.

Keep up the great work; I love this forum

PS: My wife's new 2015 3.2L KL Cherokee Limited is going extremely well. No issues, dramas, concerns or complaints whatsoever. Plenty of options to enjoy and the bloody thing drives brilliantly too

There are rumours of a V6 twin turbo petrol going into a future GC..... that would be worth a good look....
