I guess you who are monitoring the temps closely can fill me in but it all seems counter initiative.

My MY12, even without the recovery hooks, seems like the model to have - all it's issues appear to be sorted, touch wood!

If you want to know the model to have, its got to be dad's HZ 1978 kingswood. It has never had any hickups, been used to pull out stumps, even driven around Australia twice. Never had anything but oil, points coolant and brakes changed. Never a single breakdown! They don't make cars like that anymore.

Is DPF issue for 2014 CRD fixed now?

Funny, my dad actually had a 78 Kingswood SL. Chamois in colour, great car - served our family very well.

Later my brother and some mates took an ex Kingswood taxi to Darwin, Ayers Rock and kakadu. The only trouble it gave was when the dizzy came loose on the way to the Olga's and conked out. So they just kept cranking it on the starter while turning the dizzy, fired into life - done - tuned, and off they went.

Do you have the same confidence in your Jeep?

I've had 2 dpf limp attacks. A few pages back one poster mentioned getting stuck in 2nd instead of 4th. This happened to me the second time on the freeway but one I stopped at lights it switched to 4th.

I had the update at service last week. Also have torque pro running. On Friday night saw the cat temp go to over 600 while in the tunnels, dpf full was at 67%. Once I left the tunnel hit traffic and red lights. Cat stayed hot, dropped a couple of times to just below 570 but seemed to continue. Dpf dropped to 9%ish on completion.

I.e it did exactly what it should without inconvenience to me.

Contrast this to what the dealer told me when I booked the car in. They had no info that there was any fixes for dpf and that I needed to learn to drive a modern diesel. "All of the modern diesels with dpf and no addblu have this issue". He told me that the 8 speed transmission is the issue because it runs to cold. Told me that I need to force into 6 th for 10 minutes on the highway twice a month else there is no way it can regen, it's not the cars fault. I told him "Hey, it's an electionic auto, it can drop into 6th I'd it needs to". He told me the vast is not that smart. I asked him if I can have this info in writing as we don't get the diesel supplement, he refused saying that I was privileged that he gave me this "inside information" at all. I mentioned the forums and told him that everybody is getting different info from dealers so how can we trust it. He accepted that but just tried to reinforce that his info is right.

When I had the second dpf fail, the lady at the dealer that I need to drive with I different style, you need to trakt put your foot down when you accelerate in a diesel, I couldn't help but laugh. What!! I knew it was bs because that's how I drive anyway
Especially when is just me.

Hopefully this sw has fixed it. If not, I love on a really busy street and a can always put up a really big sign.

My dad had an HR station wagon with Power-Glide 2 speed auto.
It was crap.

The 1977 CL Valiant 245ci hemi 3-speed column shift was his favourite.
Never had any mechanical problems.
It did have a pretty bad leak that let rainwater down into the front footwells. The solution: rip out all the carpets, drill holes in the floor and then fish oil paint the whole floor pan. Ok it smelled a bit funny but it worked fine.
Great car.

My favourite feature was how the rear windows wound all the way down into the door cavity, with no glass sticking up. I could stick my head out the window enjoying the fresh air like a dog. That's freedom.

I don't know any new cars that can have that feature now. Not even the JGC.

.
.
.
I have more confidence in the Jeep now that I've got an idea of how the emission system works, and it seems to be working fine for mine.
I quite like not having sticky / stinky black stuff coming out the tailpipes.
.
All the dealers must have been given the same spiel for any diesel vehicle when asked about its DPF.. It's the now familiar line ... "oh it's fine just take it out on the highway for 20mins every couple of weeks"
.
.

The reason for the "drive at highway speed" story is just to ensure that the engine isnt shut down whilst the car might be doing a regen.

Just cruising at 110km/h isn't going to get the exhaust hot enough to reduce the soot in the DPF% we've seen that the temp is too low.
The engine when fully warmed up on a long drive will only accumulate soot very slowly.
Driving with the engine not fully warmed up - doing short trips - this is what accumulates the soot more quickly.


To get the exhaust temps up the only way is to load up the engine, drive uphill, tow something heavy.
Next caravan trip (Easter), I'm going to check what temps we can get and if the DPF% will actually significantly reduce at any point without a regen.
That is providing I'm not stuck in a highway traffic jam with everyone else in the rain, which seems to happen every easter

When the DPF dropped to 9% were u getting a message that a regen was in progress or is this just a burn from the temp?

Exactly. I reckon the whole driving at highway speed thing that you guys are being fed by dealers is complete rubbish.

I wonder where these dealer mechanics get their info from? Do they just make it up or is someone actually telling them this stuff? With a lot of help from Steve1307 , and a couple of others running OBD scanners we seem to have determined a whole lot more about how the regen process works than these mechanics seem to know.

It seems plainly ridiculous that just putting your foot down is going to tell the ECU to start post injecting fuel and close the EGR to raise temps enough to regen. That is just obviously wrong.

2015 EcoDiesel DEF FACTORY SKID PLATE - Jeep Garage - Jeep Forum

It appears that someone has already made a custom protection plate also.

It looks like it would need it. Our version without the DEF injector doesn't have quite as much of that dangly black spaghetti.


Edit: Oh I see from that thread that you already know about it.

Ah, so perhaps you gents haven't heard that we NA EcoDiesel owners have been having these injectors snap off by using Trail Rated EcoDiesels in such extreme circumstances as *wet highways* and *loose snow*. Madness!

Haha, yeah, the typical story is "I drove over a puddle on the highway and now my Jeep says it won't restart in 200 miles". Some genius designed the plastic DEF injector to be weak enough that one can wiggle it around with a finger, and then they thought "How can I make this better? I know, I'll make it so the injector hangs down at a 5 o'clock angle in order to better snag things passing under the vehicle! Brilliant!"

In typical Jeep fashion, none of the 2014's have protection and the 2015's only started getting that ineffectual factory plate as of March 2015 builds.

Yep, I have Dom's aftermarket plate from his first production run. It's practically mandatory. Solves the problem, though.
