Re: MIL & P20EE again & again & again...

I have DOM's plate and agree it does work well. But should you have to buy an aftermarket part to make the vehicle work as it should have from the factory.

No, but it's cheaper than the head ache that will ensue without it.

Re: MIL & P20EE again & again & again...

It seems like my mileage is down while in P20EE limbo. Between 3-5 miles per gallon. Anyone else notice this?

They also broke the bolts when replacing my cat but they replaced the pre-cat that the cat attaches too. They said "to do it right, we replaced the whole part. We could have welded or bolted it but that was not a good option" something like that. That pre cat was something like $2700 and set me back another week waiting for it. It's been about 7k miles since replacement and all has been good. I'm getting about 26mpg with mixed driving. Lovin' the Jeep again.

Re: MIL & P20EE again & again & again...

What's the best practice to prevent this issue? I've got a 2014 but it only has 7K miles on it, never gotten this code.

The dealer flashed the PCM with a 18-023-15 RRT. I called them to see if they want to flash the May 27th RRT (18-023-15A) but they looked up my VIN and said it doesn't need to be applied to mine...

Does anyone know if the earlier march 18-023-15 RRT corrects the issue? If there is an updated A version, why wouldn't the dealers computer say mine needs it? Makes no sense. I took the car in last on 22May so it was impossible for the (A) version to have been installed since it came out on the 27th of May.

I have a new CAT now and no codes (fingers crossed). It may be too early to confirm but it looks like the mileage has improved slightly.

Will inspect the dealer's work when I reinstall DOM DEF injector valve protection plate this weekend.

Re: MIL & P20EE again & again & again...

Finally... I got the new CAT, new O2 & NOX sensors installed last week. So far so good, but it's too early to be sure of anything. As far as timing goes, I had been waiting since March 27th, the day I first got in touch with FCA. They first lost the new CAT in transport somehow. Then they got one to the dealership, had my GC on the lift, but couldn't safely pulled the sensors from the old CAT and THEY too were back order, so I had to reschedule the swap and wait for the sensors... Lovely.

BTW, my air filter element is cracked on three sides... The dealership has "never seen that".

I do have a question ; how many skid plates are typically installed, and where, under a trail rated Overland ? I ask because I haven't had much time to look under the truck until now, but I did my first oil change Monday and noticed that the area around the CAT was much cleaner, with no trace of Krown rustproofing, when compared with the rest of the undercarriage. I started wondering if a skid plate would have been there, but not re-installed... Or did they wipe it clean to do the swap (unlikely). Can you tell just how much I trust dealerships ?!? Next time I see a trail rated overland, I will crawl underneath and compare the skid plates with mine. But maybe someone here can ease my mind in the mean time.

Happy trails.
Cheers,
J

90 min trip on the highway, steady speed above 65mph. Hook up 4000+lbs on a trailer and tow with it at highway speeds. Hard acceleration. Just drive it hard.

30000 miles on my '14(01 June build) - never a problem.

Well, Cat was replaced yesterday. I talked to the tech and he said he did two of them yesterday. He said it's the only thing the diesels come in for.

Anyhow, I haven't figured this out yet, but when I start it up now, there is a very low sounding hum, it seems only until it's warmed up. This is only at idle. I had the tech come out and look/listen. It "seems" to be coming from in the area of the air filter but by the time it resonates into the passenger area it's pretty loud, to me anyway. I had them update the paperwork that this started with the replacement of the cat and we'll see what happens over the next week or two as things settle in. Anyone else have this issue? It almost sounds like air escaping or a fan is on which is creating a very low toned sound. Thanks for any help.

I've never seen the inside of a dealer service garage so many times. This will be my 10th visit in less than 18 months for problems. It's my 1st Jeep so maybe the Jeep guys are used to this type of quality but I've had it. I just don't trust the vehicle. I've had a broken DEF injector from driving thru a puddle. I try to avoid those now when on the highway. This from a so called offroad vehicle. We have a Subaru that cost half as much and I trust that thing more offroad.

Rant over. Until the next time....
Two days at the dealer and they can't seem to figure out what's wrong with it. Chrysler now has a STAR case open. I mentioned the TSB for the CAT but they don't seem to think that's the problem. The dealer also said the diesels don't have very good diagnostics. That inspires a lot of confidence. I get the impression when a STAR case is open Chrysler is holding the vehicle and doesn't want to release back to the owner. Anybody know exactly what a STAR case entails?

Re: MIL & P20EE again & again & again...

Hey BlackCoffee, I understand your frustration. Don't mean to take sides, as I too just suffered through multiple CELs and useless visits to the garage, but this seems to be diesel anti-pollution growing pains (at least for Jeep). I'm hoping they figured it out with this latest CAT, time will tell. Before this diesel engine (first for me), I only had a couple of CELs with my previous Jeeps, one was related to a small emission leak, changed the gas cap et voilà. The other was the crankshaft positioning sensor (that was a painful job) on the V8. So it's not a common occurrence. The problem we've been having with the diesel, at least in my case, is made worst by the fact that Chrysler seems to want the dealerships to troubleshoot the issue over multiple visits (flash updates, DEF tests & replacement, more flash updates, more DEF tests, etc...), when in fact it seems like the fix maybe known. At least, it starting to look that way based on this forum thread alone. My service manager told me outright he was not allowed to order a new CAT until he had jumped through all the hoops (which translates to multiple visits for us). I flared at him, called FCA and that got me a new CAT on order. Took a while, but it finally got installed. I'm (really!) hoping I've seen my last P20EE. As a side note, I bought a OBDII reader, and while waiting for the new CAT, I used it once every couple of weeks to read codes and reset CELs. Always the same codes, mostly P20EE and a couple of P2BA9. The truck ran perfectly the entire time, no noticeable performance (it's not a race truck) or consumption issues. So it turned out to be mostly an annoyance... waiting, expecting the dreaded "DING".

Anyhow, hang in there, hopefully it's not too late for the wife. I want to believe I'll get the same satisfaction out of this diesel jeep as I did out of all my previous gas engine jeeps. Time will tell...

Cheers,
J.
