For cars with cable actuated accelerators and low torque, yes they can be unreliable for hills, but that is why drivers should still use their brain and apply extra throttle or brake as required.
For cars with electronic throttle and decent torque, this should be less of an issue as it can respond quicker, if the transmission is programmed correctly.
My Falcon (FG II LPi) with the 6 speed, doesnt need to be touched except for going up extremely steep hills. Sure it varies a little on all hills, but far less than I find most drivers, again, I can apply throttle if required.
For the geep, it isnt short on torque, the only issue is on descents and its reluctance to drop a gear to maintain the set speed. I find my foot on the brake fixes this, as it would for you and everyone else not using CC. The TSB for ECO off, is also supposed to fix this Less than desired engine braking during downhill descent.
My GC is getting serviced on Monday and I have asked for this to be applied. Assuming A They actually do the service and B - they apply the TSB as requested, I will check if this fixes the decent issue next weekend. I have little faith in A or B happening though, fkn Waitara.

My main gripe for the Commodore (they fixed the thumb pinching hand brake) is its idiotic CC stalk that requires you to take your hand of the wheel to engage. That and the V6 is gutless.

Steve (Barboots) agreed, I love the buttons on the Falcon, very positive that you have engaged, and well positioned. The GC, not so much, and I think the button layout is incorrect.

Crushed by an Elephant? no.... Anvil? no....... not yet.

Crushed by workload unfortunately, and under a bit of pressure - i'm an engineer <groan> -trying to design and quote a new factory
(replying in this thread is like taking a relaxing break).


Cars i've had with CC before - all were crap at it.

Subaru Turbo 1992 - very peaky, CC surged a lot
Work Falcon EL - 4sp auto. the gearbox was a bit sloppy when i inherited it - cruise hunted - car gradually fell apart but survived to about 350,000km
Work Holden - 4sp auto - gutless V6 - not torquey enough cruise was crap. - harsh kickdown under load.
Countless hire cars - usually small buzzy boxes - like that Nissan Joke i had the other week. (when they had no Jeep Renegade for me)

German cars are supposed to have the most accurate cruise control. I've Never driven a modern German car only a '66 Kombi, '70 beetle, and '73 Benz 450SEL.

When I drive I pay attention and control my speed reading the conditions.
I learnt this when I owned a little MGB fitted with a V8 squeezed into it. The handling was ... lively and no cruise control. Pay attention or be spat off the road. I still avoid all potholes and puddles because of that car.

It was pretty terrible little beast of a thing, but if i saw it on the road and i had the money "spare" I'd try and buy it back.

Anyway..
The Geep is definitely the most torquey and most techonologonical advanced of my vehicles by far so I should give the CC a chance. - Just for you.

I'd use it on the highway 110kph which is peak torque in 7th and easy in 8th so as long as it behaves itself.
but. I'm afraid might get bored if the speed is just set for me, and that leads to inattention.
I'm pretty sure there are many drivers sitting on their cruise control set at 109kph (mostly in Camrys) that are oblivious to the surroundings.



I'm having a service done late next week and will ask about the transmission TCM update too. If it does what it says its supposed to, i'll be a happy Jeeper.

From memory this is TSB 21-012-15. Correct? Please let us all know if this fixes the descent issues and the eco mode switch problem. If so, I'll tell them that I have these symptoms (I do - and the others listed) and get this done @ service time.

FWIW, I asked my dealer to look at DealerConnect for the 08-084-14 TSB (street names not pronounced correctly), since I've enabled NAV on my RJ3 (by Customtronix - very good guys!) and the dealer's going to have a quick look...


All this said, and given that this is the DFP thread, I thought that I should provide an update on my RRT 14-104 fix was done after limp mode. I can report that I've not encountered a problem since (touch wood). @Steve1307 has done an excellent job with all those OBD PID's and I now monitor the DPF capacity/CAT temp regularly.

My DPF fills to ~70% and then the CAT temp shoots through the roof to 650-700C for 10 mins doing a regen after which the DFP is down at 8% full again.

Great thread, great info. Thanks!

@Steve1307 - FYI, I have enabled dynamic lines on my Laredo reversing cam: 1 long wire and some panel pullling. But I got my rev cam replaced from the crappy FCA/JA one that dealers installed at delivery time, so I don't know if my mod will work with the crap-cam... Let me know if you want details of how to do the dynamic lines. (I threatened some time back to write this up & post, but haven't had time - yet).

I'm doing a 10K next week.

I Have requested the updated camera and wrote a letter with evidence to the dealer, and coincidentally now it seem there is an FCA letter issued last week for replacing the dodgy ones (see other thread).
I would hope to get the proper one soon, but wouldn't bet on it being ready next week.
I called the service place this afternoon and they didnt know anything about the letter from FCA.

The replacement wont have lines active, but i'm not too fussed about that - even though it is possible as it's the same model camera as the others.
You needed to pull a wire from the cam all the way up to the head unit?
I've had the screen out before and i've seen what I think is the where they spliced the crap cam in up there. (lonely wires & electrical tape).

Your DPF monitoring is the pretty much the same as what i have seen.
Kind of reassuring that it is behaving pretty consistently.

Just remember to unplug the OBD dongle before taking it in for service or they wont find the port ?!

Classic QLD right there haha.



or unless in QLD, in which case you would already be keeping left because all the locals are in the right lanes.

OT....Good luck with the camera. I had the horrendous original one, ie:the cutout which pushes up through the number plate light housing. I "gently" and politely (sort of!) threatened the dealer saying that if I ran over somebody in the dark, I would hold them 100% liable, would be talking to lawyers immediately. It was ok in daylight, virtually useless in the dark. They fairly quickly gave the go ahead for a new camera, which was a great outcome, with the replacement much better in the dark but realistically, not really much better in daylight, I'd give it about 3 out of ten, compared to others I've seen like on a friend's Caprice, however I can live with it. I don't know if subsequent replacements are better, but don't get your hopes up too much.

Back to the DPF... Did over 300 klms today, and saw my first regen today since the Dec18 update. (It's about a month since I had it done.) I hit 65% full just as I got into a section of very low speed driving up around Maleny. After about 50 klms of that, I finally hit 100 kph again on the highway (as the DPF level hit about 69%), and the regen started within seconds of hitting 100, CAT temp climbed, fuel use went up, and about 11 mins later DPF went to 8%. so it all seems good. Thanks again Steve for your PID settings!
The transmission change points do seem a little different, with more aggressive engine braking down steep hills- so much so that I tend to go to manual on the steeper hills, and does seem to drop into 8th gear at a slightly lower speed on the flat. I think I preferred the previous gearbox "personality", but still love this gearbox/ engine. There is definitely less lag on start off, and no hint of diesel clatter at any stage so far....
And Steve and Snuke please note, I used the CC for the vast majority of the klms!
(Like snuke, I hate people who won't stick to a set speed on a good road, saw plenty of them today!)

So now I'll wait and see what happens with the latest update, and will not rush in to that.

PS. My V Link OBD Wifi dongle does indeed put itself to sleep after some time, (half an hour or so) but doesn't wake up when I restart till I unplug and re plug it. Is that what others are finding with it? Not what I expected and a little disappointing!

Wrong. You arrive more alert and refreshed than if you constantly watch the speedo with the right leg stretched out to the pedal. I would never go back to a car without CC.

In Qld doesn't it depend on which lane the cane toads are in ???

Re: Is DPF issue for 2014 CRD fixed now?

New cam vs. crap cam: The difference is enormous (and it actually works during the night), but I still suspect that a FHD cam would look even better on that 8.4" display - even if its only taking a composite 480i signal.

Yes - the replacement has no lines. If I recall correctly, my replacement had a wire on the cam that was cut, so I suspect that was for fixed lines superimposed by the cam on the composite signal, not dynamic lines generated by/at the UConnect.

FYI, I did drag a single wire from rev cam to front, but didn't need to go as far as the head/console, and it was quite easy to do once I got the cable out of the tailgate and into the body. I spliced it into a terminal block near the passenger's foot. Far cleaner.

One thing to note is that the lines are both a curse and a blessing. On one hand they are a great guide, on the other, they get in the way of actually seeing the tow-ball from my caravan that I'm trying to line up on. The lines are actually quite 'chunky', and the cam is slightly misaligned from total centre/vertical, so another fix required. (First world problem).

Next (minor mod) is to put a switch in the signal line so that I can turn the lines on/off when I want them. I do want to put that somewhere in the console, so that will involve routing cables through the middle...

Guess I lucked in. My BT dongle works perfectly with TouchScan 2.7.3 on Android (with @Steve1307's PID settings), seems to switch off after ~30 mins, switches on immediately I open the door and cost the princely sum of 8 bucks off fleabay.

The only downside was that it took forever to come from 'Darwin' - which is where the Chinese seller said he was located... Liar!

I TOTALLY agree.
I hate driving any car without CC.

I even use it a lot in a 60kph zone, as it allows one to watch the road better without stressing about your speed and without having to look inside. It's a significant safety enhancement when used properly.

Re: Is DPF issue for 2014 CRD fixed now?

Well my first dpf regen experience since getting RRT14-104 applied was a bit different.

Filter was reporting 65.9% full for the past few days, I was a bit surprised that it hadn't increased after a few short trips. But last night we went into the city for dinner. We were late so I was giving it a bit of right foot. 2 mins after leaving home the obd scanner showed the filter jump to 82% full. I doubt the filter filled 16% in 2 mins, so I'm thinking the higher revs increased the pressure differential in the dpf sensors.

Anyway, EVIC pops up with the message: Exhaust system regeneration in process. Continue driving.

But I'm not on the highway, driving moggil rd and coronation drive into the city in peak hour, so sitting on 40-50kph. Stopped at half a dozen red lights, the regen continued. After 15 mins or so I was in the city almost at the restaurant and the OBD scanner says filter is 8% and the EVIC changes to Exhaust system regeneration complete.

Nice!
