OK.. just an update. Limped it to the dealership. 12 miles from the 55 MPH limit. They swapped out the nox #1 sensor, reflash, and did the regen on the recall. Still wouldn't come out of limp mode, wouldn't pass DEF quality test. And, still no codes.

Two of the guys took it for a spin with the laptop and saw that nox #2 was not working. Service quoted me $1300 to replace that and do the suggested radiator and trans fluid flush, only about $900 just to do the nox sensor only (that was 3 hrs labor). I waited a couple of days so I could call and speak to them without yelling.

I was just going to go get it and order the sensor online. But, they backed off of their list price on the part to $350 and I OK'd 2 hrs labor. So $600 plus tax and we're down the road.

The dealer is 45 mi away so that was a factor. If I paid $125 for 1 hr diagnosis and swapped it out at home and that fixed it and cleared the warning out I'd be good. But if they needed to do something for it to do the DEF quality test then I'd need to bring it back. I didn't know if the "DEF quality test" is just part of normal operation of the motor or if it was initiated by them. They implied I'd still need to bring it back after I changed it myself. I know this is not always the case and I'm sure they don't know if I'd need to bring it back either.
Hopefully that's it. Keep us posted on how it does moving forward.

The tech told me he checked the Def tank heater. I don't know. When It was replaced before they listed the resistance and that it was out of spec.

I just have no Idea how to proceed or chase down this problem with there being no codes and it still going into limp mode.

I'm sure the dealership doesn't know what to do either. I really am not happy about having to pay to be part of their learning curve.

Had check engine light come on, P20EE. cleared it. 39 miles until 65 MPH limit on DEF quailty poor warning. NOx #1 and #2 just changed. Shoot me.
I had this countdown come on about 5000 miles after the recall. I put the car in manual mode and drove at high RPMS at WOT for a while. After about 30 miles, the warning cleared. I topped up with fresh DEF too. The issue has not returned in about 1200-1500 miles.

I think this may be a residual of the recall, but not sure. If you don't mind, can you post this info in the P11DC thread, but only if you've had the recall done. You would now be the second to get the speed limit warning post-recall.

I will add that info to the recall thread if it's not already done. Thanks.

DEF quality poor warning cleared!

I had the Exhaust fluid quality poor warning and was 30 miles from 55 MPH limit. I had cleared out the P20EE code but it was run for 1 day with the warning still up. I saw where you had this countdown come on and run yours at WOT for a while and that it had gone away.

I live in a rural area. I took ours out on the road and, in manual, put it in 2nd gear and ran it at 4,800 RPMs for 10 miles (5 miles out and back). At about ¼ mile the check engine light came back on. The warning remained on the whole time and kept counting down toward 55 MPH limit. Running at those RPMs for that long felt like a strange thing to do and I was worried about damaging something. But when I turned down my road it cleared. Yay!

Torque showed the code as P144E and I cleared it out. I don’t know what that one is but I’m just glad to be out of the countdown mode.

That's awesome that my suggestion worked! :)

And yes, it does feel like you are going to break something, but I've done that many times over the past 199K miles, and nothing has ever broken as a result. It's been at least 2000 miles since mine cleared and it hasn't returned.

Only thing I would add is if you drive for an extended period like this wide open, after you are satisfied you have done that long enough, might be a good idea for some easy driving after to let the turbo cool down,it has to be very hot driving that hard, can't imagine driving 10 plus miles effectively full throttle and pull into a garage And just shut it off so hot.

Thanks a bunch! If I had somehow picked up on that earlier I could have potentially avoided a lot of wasted time and costs.

There is usually quite a bit of guessing at the dealership. This might end up being their go to maneuver for our DEF problems. Just blow the cobwebs out (then charge 3 hours labor).

That's one of the reasons this forum is so nice - we can help each other avoid those 3 hour labor charges!

high rpm's... How high? :huh: Anything over 3000? (transmission tends to shift right about there during "floor it" driving if left to its own programming. 2000-2500 during "normal" driving.)

High like right about 5000 in manual mode for a couple miles. But when I floor it in normal mode, it goes up to 4500 before shifting.
