Re: Anyone with Exhaust Filter problems

Here is my feedback after a month of ownership, I too was worried about issues with DPF as I live close to Sydney CBD and I drive into the CBD daily with plenty of start stop and idling. I also drive my cars hard, when the engine is warm I don't mind using the throttle so I would have thought this is the worse combination for the build up of soot in the DPF. So far after 1800km, touch wood I have had no issues with the DPF.

Sure it is, just dont let the EPA find out. And you would have to fool the O2 sensor and DPF sensor, otherwise the jeep might not want to run.

Re: Anyone with Exhaust Filter problems

I read somewhere here that someone removed the DPF and the car no longer ran.
I can't remember if it told him the filter was full, or what the error actually was.

Not sure if Jeep has a long term solution to this. Fairly pissed already having to deal with it twice within 6000km with a new car. I do quite a bit of highway driving travelling 80-100km/hr daily. I understand it can develop at lower speeds with lots of idling, but I'm not doing this.
Anyone else had this?
What colour are your exhaust tips? Mine are still clean as new after 4000k's. Also oil stays really clean, takes about 2000k's before I can even see it on the dip stick. I'm not using any oil at this stage. Cheers.

Re: Anyone with Exhaust Filter problems

My diesel wk2 JGC has been only doing short trips around town lately so that could be related to my problem. The last long trip (about 200km highway) returned 6.8 litres/100km (very happy) so no signs of excessive rule usage. EVIC is showing good fuel economy around town. There was precious little warning befre the vehicle went into limp mode.

Re: Anyone with Exhaust Filter problems

Ditto

My 12 day old Jeep Grand Cherokee gave me a similar message then went into limp mode. Dealer said- "too much city driving"
Has never been near a city in that time, and idling time would be less than 10 minutes.
Am hoping this does not happen again. Had to be towed 80km to have exahust cleaned out. I am getting good fuel economy.

Disappointed

Re: Anyone with Exhaust Filter problems

Yeah now it has happened again, at 2800 km.
At least Jeep has promised to replace the DPF.

Fingers crossed

Re: Anyone with Exhaust Filter problems

We have a thread going for this issue in the other forum:

Is DPF issue for 2014 CRD fixed now?

Re: Anyone with Exhaust Filter problems

Hi Guys,

I just posted the below info on the thread mentioned above, but thought i'd post it here as well in case you have any further info on how i can force regen mode, or something else i can do to resolve without taking to dealership.

thanks

G'day guys,

You can add my My14 GC Limited Diesel to this problem. Last night at about 1am it decided to go into limp mode, stuck in 4th gear and max 3000rpm. It said that Exhaust Filter is 100%. Drive at highway speeds to remedy. I did this on the freeway for 30 mins at 3000rpm non stop and it didn't fix anything.
It was only 19c temp last night, so I'm going to give it another go today, however driving on the freeway at only 75km/h is quite dangerous with everybody flying around you at 110+.
Is there any way to force the regeneration process?
I do mainly city driving and occasionally a few times a month give it a run along the freeway for about 60k. But mostly driven in afternoon after work.
Very disappointing.

Any info on anything i can do other than taking to the dealership would be great.

Thanks

Re: Anyone with Exhaust Filter problems

I don't think normal highway driving will do it. My scanner reads cat temperatures. I don't know how that relates to DPF temperatures but I guess it would be in the ball park. Anyway, to clean out the DPF one needs to reach temps of 600C. I can reach that only by flooring it up long steep hills. The car always feels better after that but maybe it's just in my head.

Re: Anyone with Exhaust Filter problems

After two cleanouts at the dealer, in the vehicles first 1800 km, Jeep replaced the DPF on my JGC 2014.
There was one successful active exhaust regen 800km later, but none since. After another 3000 km, my vehicle seems to have forgotten about active cleanouts.
Maybe the passive system is working fine? I checked the product data sheets of locally available diesel, and now use the one with the lowest sulphur-- not sure if that has anything to do with it, so I won't advise the brand. The company advised also that the correct engine oil is really important.
Overall, quite pleased with my JGC.
