It got fixed by a different dealer to where I purchased. Penrith fixed up some of the mess Waitara left.
I do wish I had purchased from Penrith instead, if only they had responded to my emails for the group purchase then I wouldn't have felt a loyalty to Alex at Waitara for all of his pro-active work.

Re: Is DPF issue for 2014 CRD fixed now?

My car came from penrith - via a broker so I never dealt with them direct during the sale. I've noted before that I had dramas at delivery and the sales dudes were completely useless. It wasn't till I got onto the dealer principal - Debbie whatshername - that things got sorted. She was actually very good - returned calls and got everything resolved. I did drop in there just before Xmas and the sales fellow who showed us the VW toureg was very knowledgable and personable. Up the other end of the dealership a completely different story with the jeep guy, had only been there a few weeks, didn't know the models - same old story. Jeep seem to get all the duds.

I have it working in the Torque app via a bluetooth dongle, but would prefer to permanently mount the scangauge, even though coding a xgauge had me thinking back to my Mainframe assembler coding days!

Oh, a big thanks to Steve1307 for the PID code definitions, spent hours looking for those, only to find them here!
Glen.

Don't know much about Scanguage other than some searching for PIDs over at various other forums Ram1500, golfTDi, ft86 etc etc etc.
I spent hours searching too.

Could never get my head around x-gauge , brain cant think in HEX.
There was one user here or AJOR with it on a WK2 "Numb Thumbs" ????? said it was difficult to set up compared to previous Jeeps.

I figured it would be vaguely, partially something like....

GAUGE: DPF Percent Full

TXD: 07?? 01 8B - mode: 01 PID : 8B

RXF: ???? 0 ??????? - 5th number 0 so don't need to scale

RXD: ?? 08 - only 1 byte of data needed but it's byte "C" not byte "A"

MTH: 0064 00FF 0000 ??? (multiply by 100, divide by 255, no adder or subtract)

NAM: DPF


Attached is the list of all of the mode 01 PIDs I could find and test on my MY14. This doesn't have any of the CJD proprietary "buried" data like trans temps etc.

The PDF of SAE J1979 2011 version I found online.
The Excel file is my interpretation of the 40-odd of them that are supported WK2 Diesel MY14.

The binary values are usually just indicating which of the following PIDs are supported. I entered in the equations where appropriate.
Quite a few are supported but give no data.

Re: Is DPF issue for 2014 CRD fixed now?

Thanks for your input Steve.

The string I constructed that I believe should work is:
TXD RXF RXD MTH
07DF018B 0441058B0000 3808 006400FF0000 DPF

When this didn't work, I went to the command function in the scangauge and entered 018B. The response was not for 018B, it was randomly giving me the output from other pid's the scangauge is monitoring, including the 013C I successfully programmed. If I issue a 013C, I get the result for that command. Go figure.
Anyway, I'll do some more research.

Glen

Re: Is DPF issue for 2014 CRD fixed now?

slight off topic. but i feel deserves a name and shaming. had my 30k service yesterday at Mansfield. They did all the recalls and flashed the dec update for the dpf issue which was great since i didn't need to mention it.
Here's the bad part. i bring my own oil in mobil 1 5w-30 give them 8litres normally and get back 0.5l got my car back late so workshop was shut. jump in the car can't find the 0.5l left they normally give me. go back in but they can't give me because the work shop is shut promises to find out tomorrow and ring me. lunch time today still no call. ring up and find out they put the 8l in and tries to tell me it takes 8.4l !! i hang up,
Go outside in the pissing rain to check my dipstick, sure enough oil level beyond the highest of the dipstick

rang them back and blasted them

i kindly tell them the my13 takes 8.4litre but my14 takes 7.7l and that is dry .
not sure if they drained it and put castrol in now since they gave me back my bottle but with castrol. no apology for waste of time. tell them castrol isn't approved by jeep but the guy has no idea what I'm rattling on about

Re: Is DPF issue for 2014 CRD fixed now?

Yeah, going a bit off topic, but I wouldn't give Mansfield anything too complicated to do. They struggle with basic stuff as it is.

Re: Is DPF issue for 2014 CRD fixed now?

yeah struggling with an oil change is eye opening oh and did i mention they tried to push an air con sanitization for $89 as well!

seriously perhaps most my14 are being overfilled with oil from the dealer leading to dpf failures?? what average person would go bother checking a dipstick after a dealer service?

I'll be opening the bonnet to check when I get mine back this arvo. Ferfarksake I never even lifted the bonnet when I got my last whip serviced at Robson Bros 4WD!

Cheers,
Steve

Not really off topic at all as one of the suggestions for DPF failure was overfilling of motor with oil and there was apparently an instruction from Jeep that the motor had to be filled to 1 mm below the dipstick full level otherwise it could build up excess pressure and cause the DPF problem. I know that when I went in to pick my vehicle up after the 2nd DPF failure (I had it serviced at the same time) they had it parked on a level floor and they carefully remeasured the level of the oil, which apparently wasn't to their satisfaction because they put a vacuum sucker down the dipstick hole and sucked some out, remeasured and declared it ok. That was at Mackay Qld. Didn't work though as I had another failure after.

A bigger phone screen might have been a good idea for entering all these numbers..


For those wanting to key this DPF monitoring thing into Torque.

Its entered manually by:

settings > Manage available ODB2 PIDs

then

"add custom PID" - which brings up a screen to fill in the address and equations.

See pic attached

.

.
The next step in the experiment is to keep an eye on the % reading as it gets up to the 65 -70 -80% range.

- We already know it can trigger at some value over 65% if the conditions are right. (XtRmn8 had one on highway at 66% and I did at %65.1.
- I don't think it will trigger a regen under 65%. I tried all sorts of "driving" methods. Even when it was 64.7% it refused to do it.
- We already know that with short trips we can get it over 70% and still no warnings. (It did trigger at 71% for me and at 72% for "Barboots"(Steve) doing short trips)
- We already know that the regen once started will burn down to about 8-10% and complete.
- We already know that the active regen sequence will abort if you switch off or let the car idle for about 2-3 minutes.

what I'm wanting to know is:

What conditions does it need to have to trigger a regen?
What minimum temperatures?
What minimum speed?
What happens if we get to 80% - does the EVIC warning kick in?
Steve1307.

You are a bloody star!!!!!!!

Got the $8.50 dongle in the mail on Friday arvo when arrived home. Got the Torque app on the Samsung Tab3 10.1 and trialled it all today.

DPF% full started at 31% at idle in the garage whilst setting it up to your specifications on Friday night. Thought I had a problem this morning when I did a run for milk and butter as it jumped to 59+ percent. Went home and picked up the family for the planned run to Augusta (relatives staying that need to see the join in the water) so having set off the DPF climbed to 64.7% (have had the Dec 19 update applied) and there it stayed, meanwhile the exhaust temps (EGT1 PID) climbed to 550 to 575 degrees and fuel consumption climbed to 9 - 10 lt/100.

A while later the DPF dropped to 8.2%. Took about 15 to 20 mins, and the fuel consumption dropped back to the 7 - 8 lt/100 mark at 110 clicks, four up.

Having completed the round trip I am now back to 59% full so will watch the meaning of life over the next few days as I am doing the 10 minute work trip before an airport run on Tuesday arvo.

I did note that the DPF% full reading varied up and down depending on what I was doing, accelerate, decelerate sitting at idle etc, so it may be a moveable feast so to speak.

At least now I have a way of monitoring the beast, much to the wifes disgust as it means I have the tablet in the car with me!! Not that we don't have two desk tops, two laptops and a bloody Ipad in the house even if I have the tab in the car!!

Regards

Adrian

Re: Is DPF issue for 2014 CRD fixed now?

If anyone is interested, got the DPF normalised trigger % working on my scangauge.

String to use is:
TXD: 07DF018B
RXF: 0541068B0000
RXD: 4008
MTH: 006400FF0000
NAM: DRP

Thanks to a very helpful chap at scangauge (James):

"Long story short, since there appears to be 7 bytes of data, the response is actually in a special multi-message format to handle large amounts of data. The commands feature doesn't really handle multi-messages, so it's going to miss the response all the time and pick up random PID's instead.

In this multi-message format, a byte is inserted into the front of the first response, which causes everything to be shifted down 1 byte from where they normally would be. Thus, PID 8B will show up in the 6th offset, and the Mode 41 response will show up in the 5th. Byte C is also bumped down 8 bits, so you end up with 4008 for the RXD."

Re: Is DPF issue for 2014 CRD fixed now?

Good stuff.

So far here is a list of what is working and the settings being used:

Steve1307: ScanTool OBDLink

paid Torque App for Android
settings > Manage available ODB2 PIDs
"add custom PID"
PID: 018B
Short Name: DPF % full
min: 0.0
max: 100.0
Scale factor: x1
unit type : %
Equation: C*100/255

Barboots:
ebay ELM327 and torque app (starting the car with the dongle in seems to trigger a MIL)

adriwood: Got the $8.50 dongle in the mail on Friday arvo when arrived home. Got the Torque app on the Samsung Tab3 10.1 and trialled it all today.

xtrmn8: I am using a cheap ELM327 dongle of ebay and never had an issue. I am using the latest version of the paid Torque App for Android.

Scanguage:
String to use is:
TXD: 07DF018B
RXF: 0541068B0000
RXD: 4008
MTH: 006400FF0000
NAM: DRP

I haven't seen anyone using ios apple iphone, etc to monitor yet..... I'm thinking of buying one of the cheap ELM327 dongles and giving a few in the app store a go. I'm guessing wireless is the better option.
