I am now convinced that my three month ordeal was caused by the dealership I was using. The new dealer ordered a new SCR, installed it the next day, and I have over 1,000 miles on the vehicle with no issues. Jeep is going after the original dealership to recoup costs that were of their own doing. Go get 'em!

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

Mine is at 16,900 miles with the MIL...code is P20EE. I went to the dealer on Saturday to check in with the service writer (having been there multiple times for various codes). He called his parts guy who told him they've only ordered two of the new cats so far...not in stock and has to be part of a STAR case for them to get one.

Reading this board, one would think all the 2014s EcoDiesels would need a cat replacement...and this is a huge volume dealer who claims they've only done two so far. So either the P20EE code isn't that common or they've found another work around to fix it besides just replacing the cat. Perhaps there are more problems with the DEF injector rather than the cat (seeing that the first step is to check DEF flow on the TSB).

Service guy said they're swamped and to bring the vehicle in to them in two weeks since it's running just fine despite the MIL. However, how long do I have before it goes into limp home mode?

I waited 3 months with the MIL on for the replacement to come in. Never went into limp mode. However with an active MIL, I couldn't use remote start on the vehicle and I was a little worried about driving it in case it did. I wouldn't give it to them until the part shows up at the dealer.

MIL & P20EE again & again & again...

Brought mine into Romano Jeep in Fayetteville, NY this morning. Got a call 5 mins ago.

Getting new SCR and DEF injector. Also getting new rear shocks after I complained about some knocking at low speed.

DEF and SCR catalyst will arrive tomorrow. Shocks are back ordered.


FYI. I have the quadra lift suspension.

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

I've had 25,000 trouble free miles on my Eco. (Knocking on wood) Love it more than any other vehicle I have ever owned. It is the most versatile vehicle ever. Great mileage and tows like a beast.
Reading all of this makes me nervous but leaves me with one question. Can anyone explain why some cats fail while others don't? Is it the cat itself or an issue upstream causing the cat to fail?

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

Just about to hit 26k miles and got the P20EE code (3x now). Trying to get info from local dealers if they have experience in dealing with this repair.

On a side note - I get an exhaust smell at idle when sitting and all windows closed. Is this related to the P20EE or something else?

Blogging my experience for others (something I hope Jeep will look into trying to make their diesel owners happier): https://conflictedracer.wordpress.co...l-p20ee-issue/

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

Remember that these are emissions related bullshˇt codes, and not anything really to do with the actual drivetrain, if that helps make you feel any better. If it wasn't for the emissions aspect, there would be no CEL's popping off. Still, emissions are a necessary evil (I'm not advocating to bypass or remove them,) and their intricacies are the reason for all these issues, not the fundamental mechanics of the drivetrain. I've had emissions related issues on BMW diesels (EGR induced excessive carbon buildup,) albeit admittedly no CEL's. VW's diesel related emissions equipment has been decent, with one issue on our TDI Touareg's SCR heater repaired under warranty.

Consider investing in a OBD-II tool ($10 and up,) and turn some of these codes off and see if they come back. If it's an actual problem and not a gremlin, it should turn the code back on. Write down the codes when you get them with the date and miles, in case you do in fact have to bring it into the dealer. PITA, I know, but it might save you an unnecessary trip to the dealer.

Seriously consider the GDE tune for a variety of reasons, one of which is to turn a lot of these silly things off. Get your cat updated first, of course! The primary reason why I went with the GDE tune was to prevent the EGR from carboning up the intake (research that topic if you haven't already done so - it's not necessarily specific to the EcoDiesel,) get better mileage (no kidding 3-5 mpg more,) and the increase torque followed by the increase in horsepower at higher rpm's.

This is a good, informative post. Without sounding like a Jeep fanboy, nearly all US diesel vehicle manufacturers have had, or are having, some kind of carbon related or emissions problems. This isn't necessarily drivetrain related in a fundamental way. Just be glad we have online forums like this, and people like GDE, who can help us deal with it.

Perhaps a shame that we "have to" tune the ecu for P20EE peace of mind, but it is what it is. I still LOVE my diesel!

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

Im gonna trade this thing in i think when i get it back in a few days. Probably go for a 2015 version of the same ride or maybe a ram.

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

Mine went to the dealer this AM for the P20EE code. Service guy says that the diesel tech thinks it is the cat but he has to go through a bunch of steps before Chrysler will authorize a new cat under warranty. Likely won't get the Jeep back until next week.

The diesel techs at Tacoma Dodge took care of me. I dropped it off with the stored P20EE before a week long trip anticipating many days of waiting for parts. The next day they call me saying DEF system tests OK and the next step is SCR cat replacement per TSB; part is ordered and should arrive next day. Next afternoon they call again and it's done. I then ask if it's OK for it to be on their lot for another five days...

Haven't done a lot of miles on the new cat yet, but I'll surely update if P20EE shows up again.

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

Back from the dealer already. No new cat. Claims the DEF tank was empty so they refilled it with 2.5 gals of DEF and presto...no codes. Of course....the DEF tank wasn't empty when I brought it in...or else the quantity gauge for the DEF tank is incorrect and that would be a separate warranty item.

So let's see if the code pops up again.
