It's got plenty of power for me. I don't think I've had the pedal down farther then half way max. Mostly I"m at 25% or less.

Glad the dealer found something. Maybe.

I can't beleive the gripes some of you have about the car. SMH. I see no reason for better brakes, brighter headlights, yada yada.

I don't think many of you would have been happy driving a car from the past century.

Carburetor, 24 mpg, square or round headlights, front disc rear drum. 100 horsepower tops if you were lucky. For a 4 cylinder motor. Running the ac, really dragged the motor down. And ac wasn't standard equipment. Adjusting points and setting timing every 3 months. 3,000 mile oil changes. No computer to tinker with.

I remember my great grandpas favorite vehicle. His very first vehicle. 1918 Mustang, I don't remember who the buggy was made by. That car was a screamer back in the day. 4 bales of hay per mile.

That's ok. All you can do is try.

Semis normally operate around the 1500 range. They don't normally go above 17 or 1800 when it's time to grab a higher gear.
When the regen kicks in. IIRC. I think it gets knocked down to 1600 or less.

I no longer drive a dpf truck. So I"m not sure on the exact rpm. The current truck I'm driving now is an 07 and I've been driving it for 2 1/2 years now.

flatlanders yeah

The dealership service department texted me the following:

FOUND P2463 PASSED AND FAILED BUT NO MIL SET AT THIS TIME. FOUND 33% SOOT MASS IN DPF. FOUND COUPLE BULLETINS INSTRUCTING TO CHECK ECM CALIBRATION. FOUND CALIBRATION UP TO DATE. NO OTHER BULLETINS AT THIS TIME. PERFORMED REGENERATION AND ACHIEVED EGT1-650F. EGT2-1200F. EGT3-1125F. (IN SPEC) REGENERATION WAS SUCESSFUL. CONTACTED TAC 8-4780278480. AT THIS TIME WITH ALER IN SPEC AND SUCESSFUL REGENERATION PERFORMED, THERE SEEMS TO BE NO PROBLEM.

The service writer then said the technician updated the ECM and performed a couple bulletins. That's conflicting information given that the technician found the ECM had the latest software available and there were no other bulletins listed to perform. With the technician doing a driving test it appears he was easily able to get the EGT above 1100F for a regeneration, so as long as the ECU triggers the regen appropriately it should have no trouble cleaning out the DPF.

It's just baffling what went wrong. I can understand I might have reached a situation where the car was due for a DPF regen and then some city driving (commute to the post office, then work) interrupted the regen enough to cause a problem. Still, the fact that driving the car on the highway wouldn't trigger a regen when the instrument panel was warning me it was desperately needed is strange. I just can't figure out why the car didn't immediately regen when I was going fast enough and the entire drive system was up to temperature.

Regens are quirky beasts with this car.

Using the Scan Gauge I’ve seen soot mass reach 20 grams (normal regen threshold) and then intentionally driven for another 50 miles on the highway and never triggered regen.

On the other hand, I’ve seen soot mass at 18 grams suddenly jump up through 19, 20 and trigger regen within 10 miles of city driving.

All this to say there are so many factors that go into the regen computations, not just soot mass or engine operating temp.

Granted mine’s a Gen 1 but from what I’ve seen here the treatment system appears to function very much the same in the Gen 2.

Glad to hear you don’t have a failed sensor or other component. Hopefully all’s well going forward.

I agree, but this is just some very bizarre behavior.

First, the vehicle has a dedicated "DPF FULL" indicator light in the instrument cluster. It's with the speedometer. I can see it light up when the engine first starts as a check on all instrument cluster lights. That indicator light never came on even when the multi-function display gave me the text readout that the DPF was full and continuous driving was mandatory. Why have a light when it doesn't get used?

Second, if the multi-function display was giving me dire warnings that I need to continuously drive the car to clean the DPF, why wouldn't it enter a regen cycle when I was at highway speeds? The fact that it wasn't regenerating when the display told me it was necessary was very strange.

Third, the display got worse for a short while when that error message wouldn't clear from the screen and the car was audibly chiming at me every 60 seconds or so. That made me nervous that something was really going to be broken over the weekend of driving the car to/from work.

The fact that the car magically cured itself was strange. First the DPF error message went away. Two blocks later all the engine power returned (and I did notice a very short regen cycle while doing some 45 mph driving on city streets). Then the CEL turned off about a day later. All this and the only stored error code was the DPF being full when the dealership technician was able to determine the DPF was about 1/3 full when I arrived at the shop

I honestly hope the problem goes away. I don't want intermittent issues to come along that the dealership can never diagnose unless I bring the car in RIGHT NOW when it's happening, because that's always a major pain to deal with.
