Re: Does the DPF regen system make Diesel unusable as a full time work vehicle?

As long as you get some highway speeds on a regular basis, you shouldn't ever have DEF issues.

Re: Does the DPF regen system make Diesel unusable as a full time work vehicle?

Our 2008 CRD also had a DPF and it never caused any problems over 120,000 + miles. Every once in a while you might notice funny smell if the regen is still running when you are idling.

Re: Does the DPF regen system make Diesel unusable as a full time work vehicle?

I'm at 4 months/4k miles and I have never seen an "active regen" (i.e. I have never seen a message about it). I know it's happening behind the scenes, though. My short, city-only, long-idling commute means I'm getting 17 mpg on summer blend. I guess my point is that if I am not experiencing trouble with the duty cycle then I doubt others will.

I do need to get the PCM flashed for the TSB because my oil is showing 18% life remaining.

Re: Does the DPF regen system make Diesel unusable as a full time work vehicle?

If all you do is drive to church on Sundays then yes, you might have to limp home once in a while. But if like most of us, you enjoy your Jeep, give it a bit of stick up long steep hills now and again. That should keep your DPF nice and clean. Besides, having all that torque pushing into your back feels great. The diesel likes to be worked.

Re: Does the DPF regen system make Diesel unusable as a full time work vehicle?

I don't think hard driving alone will clean the DPF unless you are towing or pulling a ling steep grade. In fact, more soot is generated when you plant your foot. The EGTs on mine never hit 1100+ long enough to regen on flat ground before I'm seriously over the speed limit!

I have been watching my EGT and resetting my trip meter after each regen event. The frequency has ranged from 70 to 270 miles. No rhyme or reason. Anyone else notice this?

I know you have both a ScanGauge-II and a BT+Torque - which are you using for monitoring EGT? I could swear I read in another post that you were using your ScanGauge for at least the cat temps. I don't seem to get cat temps from my ScanGauge, so I'm wondering if you have a newer version or if you got the code and added a manual gauge? If you didn't add it, any chance you can let me know what firmware version you have?

Re: Does the DPF regen system make Diesel unusable as a full time work vehicle?

I was waiting for someone to ask what the ScanguageII's Xgauge codes are for EGT. The JGC uses CANSF codeset and the Xgauge codes for CAT Temp F and C work as listed on their website. Its Bank 1 sensor 1.

The codes for CAT F are:

TXD: 07DF013C
RXF: 0441053C0000
RXD: 2810
MTH: 00090032FFD8

I called it "EGT"

The code for CAT Temp C is the same except MTH: 0001000A0000

http://www.scangauge.com/support/x-g...ansf-vehicles/

I tried all the other CAT banks/sensors in hopes that one would be the upstream EGT that the Torque app can read. I wish there was a way too see what codes Torque is using. I even tried the PID scanner add-on with no luck.

FYI...the BlueSpark has no display. Its just an underhood box with a tiny rotary switches.

My Scangauge II sits in the cubby with the cable routed through the back and under the dash.

If that's in regards to my comment about BT+Torque, I was referring to BlueTooth+Torque, not your BlueSpark - I know the BlueSpark is just a box with switches.

That's where I keep mine too, though I haven't gotten around to routing the cable under the dash and through the back.

Its pretty easy if you use a stiff piece of electrical wire as a "fish tape". Run it through first then tie the cable on and drag it through.

There is a gap in the roof of the cubby at the rear of the cubby door edge when its open. You have to tilt the door down to feed the wire through. You are aiming for an exit point located at the end of the plastic seam you see between the upper and lower console panels. Follow that seam towards the gas pedal and there's an opening there to pull it through.

Re: Does the DPF regen system make Diesel unusable as a full time work vehicle?

There were typos in my other post. I fixed them. Here is what I am actually using....

The codes for CAT F are:

TXD: 07DF013C
RXF: 0441053C0000
RXD: 2810
MTH: 00090032FFD8

I just got a bluetooth OBD adapter and the Torque Pro app. From your quote regarding the ScanGauge X-Gauge codes you are using for "EGT", it appears you are using Catalyst Temp (Bank 1, Sensor 1). Torque offers this as a sensor, and I have been receiving data from it. It also offers an "Exhaust Gas Temperature 1" reading that is similar, but seems to have a slightly lower temp reading (at least during the brief jaunt I used it for yesterday).

I won't say that my experience thus far with the scanning system has been painless. In fact, Torque or the adapter caused the BCM to freak out, throwing CEL codes that kept returning, having EVIC repeatedly display a "Service Shifter" message, EVIC going crazy moving through various displays, etc. That was "fun" (especially when the CEL kept returning after repeated clearing)... my guess is that this was due to the "thorough protocol scan" option in Torque.

I also have missing options for sensor data that Torque says the adapter indicates are available (e.g. variable geometry turbo, turbo RPM, etc). I also can't seem to find a way for it to indicate the fuel level. Perhaps I will figure it out soon. I just hope there aren't any more faults.
