Re: Is DPF issue for 2014 CRD fixed now?

In October last year we towed a 3.5 tonne off-road van from Brisbane up the inland road to Charters Towers then across to the coast and up to Cairns. Then we went up to Kuranda which is a twisty up hill with road works and slow sections and back to Brisbane. I saw temperature rise and was concerned but it soon went down on the flats. I was very happy with the tow ability of 2014 Overland with 25000 on the clock. I am also sure that the particle filter did its thing but I must admit I was a little worried with being on some of those long stretches with all the talk on this forum at that stage. I did get a message about 6 months ago when I was on Coronation Drive in Brisbane to keep driving and was prepared to bypass Brizzy and head down the highway but the message disappeared before I got to the city. I have had all the upgrades in January so I hope I can relax now with my good towing experience. Thanks for all the insight into the DPF on this forum

Re: Is DPF issue for 2014 CRD fixed now?

Had my first (8050km) Regen yesterday! I don't feel like such a noob anymore! No problem, just said "continue driving", no idea if or when it finished as I changed my dash read to see temps, couldn't see anything different. Am I missing something?

The car will have done regens before with out any notification. Just that this time you managed to properly fill up the DPF enough to trigger the message.

When it does a regen cycle the Oil temp (or the water temp) does not change.

The exhaust Catalyst/DPF temp sensor shoots up from normal 250C ish up 650+ C. (this is not displayed on the EVIC).

You might notice a little bit more fuel consumption on the EVIC, maybe +3 L/100km more depending on how you're driving at the time.

Latest report all.

I was trying to fill up my DPF to trigger the 80% message again, but the thing did me over tonight.

On the way home from work, a 15 minute trip I was watching the DPF % Full dial on my tablet, as I have been since the last message and it continued to climb. Up to 78.1% part way through the trip when I noticed that the exhaust (EGT1) temps were raised ad the Cat Temp (CatB1S1) was climbing. They ended up in the region of 550 - 575 and 650 - 680 degrees respectively. After about 10 mins I stopped the car for my personal fuel (heavy red), and on restarting the DPF dropped to 26.2% and temps dropped back to normal.

Obviously had I continued driving then the DPF would be back to about 8.2%, but now the watch starts again.

Regards

Adrian

It won't overheat, tried to cook mine up Kangaroo Valley towing my van, just sat below the red no matter how hard I pushed it.

Interesting. On a long climb though when you see that needle climbing you think "JUMP!! She's gonna blow!!"

Did use aircon on a more recent towing adventure without drama.

Re: Is DPF issue for 2014 CRD fixed now?

OK, I'm impressed with the knowledge shared over the past few pages regarding the the engine diagnostic apps and OBD2 adaptors. But can we dumb it down to my level.

I own a MY14 Grand Cherokee with the 3.0 diesel engine. I want to purchase an app and adaptor primarily so I can monitor the DFP levels and be able to reset the engine management light if I am in the middle of nowhere and trouble strikes, and to monitor temperatures when towing a caravan. I will be using an iPhone or iPad. I know it needs to be WiFi, but which is the preferred adaptor, and which is the preferred app?

Regards

I'm sure he was talking about turning off the Aircon to avoid overheating, not for more power of less fuel.

Turning off the Aircon WILL help any engine a little bit with respect to overheating.
The Aircon condenser just adds more heat to the airflow just upstream of the radiator.
On my old Patrol, turning off the Aircon and even turning on the heater, made a significant difference towing up a big hill. (I hope I don't ever have to resort to that on the Jeep.)

I agree, mine is almost never off. (Queenslander of course!)

You need a WiFi sender, like this:
Vgate Icar 2 OBD2 OBD ELM327 Wifi CAR Diagnostic Scan Tool Android Iphone Ipad | eBay
(The better option as it puts itself to "sleep" so very little battery drain.)

Or this:
ELM327 Obdii OBD2 Wifi CAR Diagnostic Wireless Scanner Tool FOR Iphone Ipad Ipod | eBay

(Cheaper, but stays alive and will flatten your battery over time. If leaving for longer than overnight, needs to be unplugged which is a nuisance. I've had that one for a while but recently upgraded to the first one which goes to sleep.)

If you have an android device, you can go Bluetooth. My son bought a CHEAP dedicated Android tablet for his car. With Android you use the "Torque" app.

You then need an appropriate app on your iPhone of iPad, "Dash Command" works very well but no "custom" settings to monitor the DPF yet - they did say it may be available soon, so the next best option is probably "OBD Fusion" which allows the custom PID setting Steve1307 gave us for monitoring DPF.

Now I virtually always have the iPhone connected to keep an eye on things, (except for very short trips like down to the shops), or the iPad for all longer trips and towing.

Hope that helps.

Re: Is DPF issue for 2014 CRD fixed now?

i wouldn't say that a wifi obd2 is the only choice.

i'm using a bluetooth one. i've tried it connected to torque pro, whilst talking on the phone via bluetooth nil issues and streaming bt mp3. obviously the call interrupted the music streaming but returns to bt mp3 streaming when the call ended whilst using torque pro still.

havent had a flat battery so i think it does goes to sleep
the evic screen does flicker when the car is turned off and is stil connected to torque but stops when i turn off torque

You clearly have an Android device, these can use OBD II via Bluetooth. With the exception of the GoPoint BT1, iOS must connect via WiFi.
