I currently have my jeep sitting waiting for a DEF tank line filter that has been back ordered for 2 weeks. My check engine light kept coming on and was reset twice. The third time the dealer found that DEF had precipitated in the tank and the actual filling tube down to the tank. This clogged the filter. They have to remove the tank and replace the filter. They initially tried to say I put old DEF in the tank. That must be Jeep's standard talking point on this issue. The service manager agreed that I didn't do anything wrong. The DEF I added was Mopar and was kept at 70 degrees and was unopened. So, I am now wondering if/when this will happend again. It is a major pain in the ass. The fact the filters are back ordered makes me suspicious that this is a flaw in their design that others are now experiencing in number. This is very concerning to me going forward. Nobody can say why this happened really. So then how do we prevent it from just happening again? My jeep has 8K miles on it.

I have a Ram 2500 Cummins and I've been putting the Peak Blue in it since the beginning. I haven't experienced any issues with it so far and I've probably added at least 5 gallons or so. It sounds to me like the the Jeeps had a bad batch of DEF because it shouldn't be crystalizing like that.

I have tried using peak Blue DEF (purchased at autozone)in my Grand Cherokee and the check engine light comes on saying I am using the wrong DEF. I noticed others on the forum buying the same DEF and was trying to determine if there are others with the same issue. Please let me know what brand you are using and if you have any issues

Thanks

I wouldn't be surprised if AutoZone was the problem. I've got 12K mile on mine. It came with about 2 gallons. I added Peak DEF purchased at a high volume truck stop, no problem. After another 5000 miles I bought 5 gallons of DEF at AutoZone. The got the error messages and the engine waning light. A diesel mechanic I know told me that either old DEF or DEF that has been stored in the sun above 90 degrees will often trigger the manufacturers error messages. I week later the dealer told me exactly the same thing.

I went with Valvoline Premium Blue. Bought at NAPA store. ( Same thing- dealer didn't 'top off' as supposed to ).

I was coming up for our 2nd LOF and needed more DEF.
I located a Mopar dealer selling 2.5 Gal DEF part number 68056278AB for less than $17 delivered. Fresh stock.
Purchased it online and shipped to south FL...date was 8 week old stock.

Sent the invoice to my local Jeep service department and they agreed to match the price. I just picked up two more 2.5 gallon MOPAR branded DEF containers and the stock is the same, less than 8 weeks old.

MOPAR packaging company is Cul-Mac, Wayne, MI.
I will document all DEF purchased, when and "born on date" IF there are any issues as some of you have stated in their posts.
At this early stage and newness of the engine, we will stay with the OEM branded product, but glad I was able to get the cost greatly reduced.

Spent some time with my brother in St Louis, MO. He is a merchandiser for fertilizers. He said the DEF industry is growing quickly and will be a huge commodity. maybe its time to invest into something that can only go up???

 

[Bogeyman2B]

Update
After adding 5 gallons of the MOPAR branded, fresh stock DEF...I get a call from my wife on her way to work. Message concerning DEF came up..."Incorrect DEF, contact dealer" Really?
Will be calling the service department this morning.

I have a 2014 Summit Deisel (Summit). Picked it up in December 2013. I have 16,700 miles on it. Love it. I have put PEAK DEF in it twice. Actually, the consumption is not the bad. I beleive I have only put in 7.5 gallons at 3000 miles, and just added another 7.5 at 16,000. I do a lot of highway. This last time, the light came on, and that prompted me to look at the DEF Level. I put some PEAK DEF in, and the light didn't go off. Took it to JEEP. They said the light came on because the "system" did not know if I had contaminated fluid. Recommended I use the more expensive Chrysler fluid, which, by the way, the Parts department had a hard time finding. I didn't buy it, but wanted to check the price. In any case, the PEAK DEF from Autozone says it is certified to the same specs as the the manual requires, so I am not sure how this could not be totally acceptable. The Jeep Mechanic implied there might be a warranty issue without using Chrysler DEF. So, the light is now out, I'll keep my eye on it. Thanks for al lthe great input. On a side note, I have gotten a low of 22.5 MPG on a tank, and my best, a couple of weeks ago was 31.5 MPG with mostly highway, and averaging about 70 MPH. Cheers

Blooleader you're dead on about using the correct ISO number i posted some time ago. Fresh stock, etc.
I actually posted who is packaging the product for MOPAR and since I'm in the chemical business, have a pretty good idea who manufacturers the glorified chicken urine.
However, since the engine is very new and they do NOT have the software dialed in yet, I am only buying MOPAR 2.5 gal jugs, pressed my dealer to match another at $17 per unit...everything is documented.
I will have no tolerance for these issues of not "using non mopar products".
Lastly, even after only adding their product, we got the error message of incorrect DEF anyway. 3 days in the shop to upgrade the software at their expense for a rental.
Today, the engine icon came back on and no messages. This is getting old very fast for investing this kind of money.

I am under the impression that DEF is DEF is DEF . As long as the percentages of urea and pure water are correct and there are no additives there should be no problems. A chemist given samples of MOPAR and Blue should not be able to tell them apart.

The sensor wherever it's located must check for specific gravity or conductivity or who knows what....... It could be bad or worse intermittent.

Heat shields between DEF tank and particle chamber could be breached and when the vehicle regens water could evaporate changing the mix.

I buy my DEF wherever I find it...... Whatever brand...... Make sure the level is low enough to take two (5 1/2) containers and discard remainder.

Perhaps the cap on the DEF tank is loose or doesn't seal properly allowing evaporation of the water part changing the mix.

My guess is either the sensor is bad or something is happening to change the mix.

Perhaps the line is pinched and the flow isn't fast enough and the DEF in the line to close to the heat is causing the problem.

I do not think it's the DEF.

Just some FYI on DEF
I just got almost 10,000 miles out of the DEF from FLYN J
LOVES truck stops in Phoenix also has DEF and it's $2.69/ gal
I have a little over 17k from truck stop DEF

 

[Casper2]

I have seen those DEF pumps at the truck stops..... but they were always over on the big rig side. And I was always there when I either didn't need it or the rigs were backed up waiting for diesel. To date I have spent $36.00 over eight months on DEF and have 75% of a tank left which is what I started with. But I would not hesitate using them if the timing were right. I got my JGC on 36 months 0% interest plan so every month they suck $850.00 out of my $ tank. In a few years when that's over maybe I will start thinking about the $4.50 a month I spend on DEF.

Sorry - having some computer (or user) issues this morning:

Bogeyman2B - Can you share where you found it online? I see it available online at several places but shipping is outrageous, I would be better off to just pay the shelf price at my local dealer.

For Everyone - I see there is an AB part number and an AA part number...anyone know if there are differences between them?

Last question - I purchased a 2014 Summit with the diesle and it was certified, I didn't think to check on the DEF level before signing and driving and its down to 20% already...shouldn't they have topped it off as part of the certification process??

 

[GRIM_REAPER_76IA]

When I ordered my 2014 Summit CRD I asked the dealer to make sure they topped off the DEF tank and when I was called to pick it up the sales person checked it for me and had it filled with no problems.

I picked my 2014 up on 5/31/14 with 6 miles on it and as of today 9/19/14 I only have 2586 miles on it. The DEF gauge shows I still have ~ 80% remaining. I purchased the Summit in Illinois because the dealer I have by me in Iowa does not like to negotiate very much. The dealer in Illinois quoted me $7.50 for 1 gallon Mopar DEF and $18.00 for 2.5 gallon DEF. My local dealer in Iowa wants $13.00 for 1 gallon and $30.00 for 2.5 gallon. I plan on buying it online through Mopar Parts Overstock unless my local dealer will match the price. Here is the link to their prices.

At the Mopar link below it appears the AA and AB according to them differentiates the 1 gal. vs 2.5 gal. bottle.http://www.moparrepairconnection.com/chemical/action/guide/en_US/DIESEL FLUIDS/

I used fluid which matches the standard listedin the owners manual. I think the brand is BLUE.

Purchased the OEM 2.5 GA DEF from a TX distributor, included shipping.
My local MOPAR dealer/service dept matched the price.

 

[ExcursionDiesel]

The pre delivery service for our vehicle specifies that the service department is supposed to add DEF. There is a document that details this. Dealers are supposed to do this and file for factory reimbursement. It is rarely followed. Mine came with 20% which is all the factory provides since they don't know how long it will sit in a lot and the dealer fill up will "freshen" the tank later.

I have had all these problems too. Low DEF in June whilst on vacation in Oregon . Called a dealer told me where to buy DEF in Astoria and I did same and added to the tank .

But dealer did not know how much it held . Checked with dealer in Mcminnville Ore he told me to go to O' Reilly auto parts . Here I bought 4 cases and filled the 8 us gal tank .

Did about 4500 mile no problems till Aug when leaving Florence warning light saying incorrect DEF 200 mile engine will not start .

Spent the weekend in Wood Burn north of Salem and on the Monday went to the Salem dealer . Here they drained the DEF tank and refilled it and they blamed

not using Mopar DEF but after market DEF namely Blue Def. Contacted Blue Def and they told me their product was the same as Mopar.

And sent me the corresponce they had received regarding these issues. And they thought the issue with the vehicle's SCR system.

Tried claiming on Chrysler but they told me in Salem they did a service and not a repair. Last week I had my oil and filter change done

at my local dealer here in BC also they changed the water pump which was leaking . And they also did the 25080490 RRT 14-075 kit 68257352AA.

Cause : 25-08-04-90 DEF injector Assembly , DEF injector Line ,Secure [1 -Semi -Skilled]. 10 - Diesel.

Correction : 25-08-04-90 DEF injector Assembly , DEF injector Line Secure [ 1 - Semi- Skilled].

When I had spoken to Chrysler about my Salem repair they knew nothing of the RRT 14-075. I called my dealer and they told me an RRT is before Chrysler receive

the info to generate a call - back and to recall Chrysler on Wed after they will have the info. That will be the 8th of Oct.

Using MOPAR.

Heard of too many issues and warrantee problems when you don't.

Peace of mind for me.

 

[Casper2]

Same here.
