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.

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.

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.
