Re: Incorrect DEF - See dealer

If your dealer had your car for 9 days now with "incorrect DEF" and "Car will not start in 175 miles" and an SA that wants to replace the catalytic converter, what would your next move be?

I might see if they'll drain the DEF, add a gallon of new stuff, and drive a hundred miles to see what happens. I'll take any and all advice.

From what I've read, the ECU has a number of emissions self-test that are done on every "drive cycle". A drive cycle requires the motor to go from ambient to 160F and a certain number of miles driven. You can see the results if these test using the Torque app and an ODB2 adapter.

The error you are getting will not clear with a reset. In a properly working system, it will clear when it sees NOx emissions that are below the required threshold after x number if drive cycles. Bad DEF will cause these test to fail. Replacing with fresh DEF and driving several short trips (drive cycles) is the first thing to try. Mine reset in about 3-4 short trips (30 miles total) and 4-5 restarts. The last restart was in my driveway after it sat for an hour. The "xxx miles remaining - see dealer" warning went away and the stored code in the ECU cleared by itself.

Re: Incorrect DEF - See dealer

Well...my CEL and warnings are back. Scratch EVERYTHING I have said. The CEL returned and "Engine will not start in 170 miles" displayed. This makes no sense because the last message said 180 miles before it stopped displaying and I thought it was cleared. That was 150 miles ago. I guess I am now forced to go see the incompetant service department.

The only possibilities I see is that the DEF fill marginally increased SCR efficiency but only marginally and now it is back...or I have a bad NOx sensor.

Codes are the same P2BA9 and P20EE.

I hate this EPA garbage.

Sorry to hear the problem returned.

Perhaps if you want to take one more shot at this before bringing it in for service, you could completely drain the DEF tank.

The DEF tank is located just forward of the fuel tank and the fill hose has a disconnect where it enters the tank. If you pull the hose, you should be able to siphon the tank from that location.

Good Luck. Please keep us posted.

Re: Incorrect DEF - See dealer

The P20EE is the code driving my dealer to replace the catalytic converter. They drained and refilled the tank already. However, they hadn't driven it since. I picked it up to give it some drive cycles while they wait on the part in the hope of clearing everything.

Last two trips I heard the slight "chirping" on shut down, which someone posted having to do with the DEF. That's got me hopeful that things might be moving again. 170 miles left til shutdown. We'll see.

Re: Incorrect DEF - See dealer

I'm attempting to drain the tank tonight. I hope it works. I have an appointment tomorrow with my dealer at 8am otherwise.

My information about the DEF tank location might be incorrect. I was thinking about the Ram (not the Jeep). Must have been a senior moment

Re: Incorrect DEF - See dealer

Its under the spare tire well and between the bumper and axle. There is a quick connect fitting in the left rear corner on top. Its gonna take a 3/8 tube. Gone to the store....

Re: Incorrect DEF - See dealer

Whoever designed a tank that holds short term perishable liquid with no way to drain it is a freakin idiot.

Excursion, quick question. Does your wk2 have the ORA2 skidplates? Wondering if they could help act as a heat shield against hot summer asphalt cooking the DEF? Thanks.
