Yes it was Jeep Osborne Park. Thus far I do not have any complaints and have been happy with their service. My service was cheaper than I thought it would be plus I had a few warranty items fixed and even my wheel alignment was covered by warranty so I am happy.

As Steve1307 has posted, the DPF does not hold much at all and from the data logging that a few of us are doing a DPF regen process occurs every 500-1000kms based on the type of driving you are doing. So even at 1600kms your car would have done a regen or two by now or you would have been on a tow truck by now.

70% of my driving is at 100km/h on the freeway and the DPF is still filling at this point, but not as fast as it would doing shorter trips when the engine is warming up.

In my case my car is doing a regen about every 800kms and the process only takes about 10 minutes to complete.

Re: Is DPF issue for 2014 CRD fixed now?

My service was cheaper than I thought it would be plus I had a few warranty items fixed and even my wheel alignment was covered by warranty so I am happy.

Could you tell me how you get a wheel alignment under warranty?

Had to pay for my own when both front axles were replaced.

20K service they charged me for a mandatory Pollen filter change out in the AC unit.

As to my Laredo sounds like the DPF is working as it should all along, running smooth and nice shift changes etc.......hope the latest update doesnt change any of that.

Cheers,

Rocksfly

I am pretty sure there is a TSB for the MY14s related to them leaving the factory with bad wheel alignment.

There is a whole thread on it here somewhere.

So glad you are happy with their service XtRmn8. They were the ones that tried to baffle me with science when my GC went in with the dreaded DPF lurgy.

Apparently I was naughty as I only did short 'mummy' trips taking the kids to school, and around the burbs.
And to stop it happening again.........I needed to warm the car up for 5 mins before I took off each morning. And that I should add some additive to get rid of the soot once a month.
All said with a very patronising tone - and trying to talk in as few syllables as possible.

All he had to do was look at the mileage on the car - 14K in under 8 months, and dressed in a business suit, to deduce that maybe it wasn't the short trips, and maybe I just didn't do short school trips all day.

With that patronizing treatment wouldn't go back there if they paid me.

I couldn't get them to do an alignment when they changed our the front axles. Paid for it myself got it done by the mob around the corner from the dealership. Warranty guy told me they get ask their Jeeps done there.

Bought the vehicle 2000 Ks from where it gets serviced... Bit hit and miss, even had to insist they put the vehicle back on the hoist agree the last service to rotate the tyres. 25000 kms and still couldn't do as requested initially.

Thanks I'll go look for the TSB.

So the OBD2 dongle arrived and I plugged it in then spent about 30mins trying to work out what I was doing.

The button seems to wake up the reader, but doesn't power it off. The manual says it has a sleep function after 30 mins.

Took me a little while to work out the car had to be ignition ON rather than just accessories..... doh!

Then it took me a while to work out how to get to 'menu' in torque. I'm not use to android phones. But once I worked out the bottom left hand button is the menu button I was able to add the custom pid and it told me the dpf is 22% full..... so looks like its working ok.

Re: Is DPF issue for 2014 CRD fixed now?

Good News for you all around Benn0, looks like both the regen and the obd2 reader and torque are working well. It is a bit of a comfort to know what the percentage is. I do long trips interspersed with a lot of short ones. One thing having the reader has taught me is that the dealers really haven't a clue how the regen system works. The regeneration will not take place unless the percentage full is up around or greater than 60% so taking a run on the highway when it is less that this is just going to waste time and fuel. On the other hand, without the Jeep telling you that the DPF is nearly full, with a series of short trips it is likely never to get to a point where the conditions are met for the burnoff to occur, at least now we know when we should be going for a bit of a lengthy trip, and it doesn't have to be at highway speed.

Things I would like to know with your new dongle is, 1. if you leave it in whilst stopped and it enters sleep mode, does this stop it draining the battery and 2. When you restart the vehicle after being stopped does it cause the evic to flash so that you have to remove and reinsert the dongle to over come this?

I'm not keen on testing 1. LOL But according to the broken english in the manual "don't need to draw the KW902 after the car stall (but still have power supply), 30 minutes later it will automatically come to sleep mode and stay in power saving condition. Tomorrow morning or next time to start the vehicle you can use the KW902 directly only by press the switch not need do plug again....."

I'll try 2 later.

Certainly it would have made a lot of sense for Jeep just to make dpf full values available to read in EVIC.....

Shouldn't laugh, but I will take the broken english manual over the non-existent Jeep one any day. And I certainly don't blame you for not taking the first test.

Its a really good point youve made here. There is a pretty small window of opportunity to regen if it is waiting until >60% full. The driver really needs to know when its time to do a highway run (or a ~20min drive with no stopping and engine at full operating temp)......

You might have to shut down the Torque App when finished with it to make sure it disconnects the Bluetooth link with the adaptor and then it will sleep. (Not sure if that is essential but I read somewhere about someone in the US flattening the battery on their "GM Volt".

Barboots(Steve) also starts the Torque app after starting the Jeep as he got some error lights on the dash when torque was already running.



Now that I know how the DPF / regen works I generally don't run the app normally when driving as its a distraction.
I might check it just before shutting down to see the % if it's getting close. I think i'm up to about 48% again now.

Interestingly after observing a few times:

Driving on highway speed for some time prior it'll regen when it gets up to 65%.

Driving slower and shorter trips it won't regen and will go past 65 and it still won't regen even as it goes up past 70%.
If I've shut the car down wit the level over 70% (or 71%) then it seems to commence a regen on the next run when the car is fully warmed up.

There is another simple PID for the "number of warmups" and it adds 1 to the counter when the engine gets past a certain temperture & run time.

No. of warmups
Mode: 01
PID: 30
units: none
Equation: A

When I do the next regen I'll see if it triggers at the same time as as the count indexes. And also observing what Coolant and Oil temp it changes the count.

I still have no idea how to get it over 80% for a EVIC warning.

Re: Is DPF issue for 2014 CRD fixed now?

I can confirm what Steve has said. I live in a rural area, so drive at 'highway speed' everyday. As soon as the dpf reaches 65% and the engine comes up to operating temp, it regens. Approx every 850km.

Glen.
