5000 miles and Check Engine Light on

Sure like your attitude and welcome.

Have also heard of a very few sensor issues similar to yours. Think there's a sensor going to that Diesel Emissions Fluid canister that's been replaced by a few. Not sure.

Sadly it's an issue common to probably all diesel engines today. They most all have a form of Diesel Particulate Filters followed by a DEF filter. Both use sensors. Sensors sometimes make no sense.

It's the computer age. You just might be a kid that lives with that stuff and can understand. If not, you will soon be miserable like me.

Problem is not the engine or transmission. You just might get it with anything you buy today. Give them time to sort it out.

Not to worried about it, truck is still running fine and getting great milage. Luckily where I work we sell the def fluid, just added 2.5 gallons because I was down to a quarter of a tank and it only brought it up to 1/2. must be about a 9 or 10 gallon tank bigger than I thought it was. Seems to be using a lot. I do not tow just a lot of driving.

Surprised it used that much so fast.

One thing to remember is DEF is available in bulk at most all Pilot and Flying J stations. Probably also at other major truck stops. Just don't really know yet.

In bulk it's $2.79/gallon most everywhere. To buy in a gallon or 2 1/2 gallon container makes it way more expensive. Bet even as an employee you paid more than bulk price.

how much cheaper is the fluid where you work, i'm assuming you get it at cost or at least a discount

I can get it in bulk but I just bought the 2.5 gallon because I thought that would be enough. lol I paid like 9.00. Between the container and hose and the pretty box I thought that was fair. Lol

not bad at all!

Well, guess what? Little over 4k and the engine light is on. Checked the manual said it could be driven and should go off, (also says that if it's blinking shut it down) some thing about it resetting after a while. Now it's been 10 days. Called the dealer and I'm suppose to take it in the 14th. Anyone think this is a ongoing thing?

Got a check check engine light at 1000 miles plugged in my bluetooth odb2 and pulled the codes P1DB8 P1D90, powertrain codes, looked under my truck and saw lots of fluid.... Yay

Well this thing is making me a liar, drove it about 40 miles yesterday, went into Lowes came out started it and the engine light went out. Guess I'll still keep my appointment in the morning and see if they can find some codes on it.

First, that blows and is not reassuring to hear. I dont think that it'll cause any problem down the road to drive. As for side effect, if its the emission sensors like the O2 or NOx then you may go through more DEF.

Check Engine Light

So far it has not used any DEF fluid, but we will see. After researching I am guessing that Chrysler is redesigning the sensors. The dealership said the truck is regenerating, so that is good. However, the check engine light came on 3 days after they turned it off. When the check engine light is on the remote start does not work.

Took it in this morning and the code reader said it was a bad fuel mixture.

sarcastically, I would have asked, what constitutes a bad fuel mixture on a diesel, but I guess the tech wouldn't have a clue.

Service mgr was the one who checked it and flat told me he had no idea what would make it come on, he thought maybe bad fuel or air mixture, he flat told me he had no idea what made it come on and that all he could do is read the codes, and it said bad fuel mixture.

I did run most of the fuel out and filled it up before it went out. Bad fuel?? Maybe, maybe not. Air mixture doesn't sound reasonable, it's not going to change. Will have to wait and see.

I'm surprised nothing was learned from the couple years the GC has had the Motori available. Either there is little to no sharing between brands (unlikely) or there are so few Eco GC's nothing was actually learned...

Good point. My dealer sells Jeep, Chrysler, Dodge and Ram. They have been selling the Eco Grand Cherokee's. I do not know their level of experience but it should be reasonable.

If the selling dealer did not sell Jeeps, that is a real good point.

I would say it is probably due to totally different electrical systems.
