Your post above just now IS EXACTLY WHAT YOUR PROBLEMS ARE!!!... > THE FACT THAT YOU ARE NOT TAKING MATTERS INTO YOUR OWN HANDS BUT KEEP TAKING IT TO.. AND LISTENING TO .. THEY!..

WHO ARE NOTHING BUT THE COMPLETE GAGGLE OF OEM-CERTIFIED, INCOMPETENT IDIOTS WHO ARE ONLY EXPERTS AT TAKING YOUR MONEYS ENDLESSLY AND SHOVING PARTS AT IT AT YOUR OWN EXPENSE UNTIL YOU GO OUT OF BUSINESS OR IT MIRACLES THE PROBLEM TO GO AWAY AFTER ENOUGH GUESSING!.


IF YOU DON'T START WAKING UP AND TAKING CONTROL OF THIS.. THEN YOU WILL CONTINUE TO BE TAKEN FOR ALL YOU ARE WORTH!@.


YOU.. NO ONE ELSE ... BUT YOU!!... THE TRUCK OWNER.. CAN FIX THESE KINDS OF ISSUES WITHOUT SPENDING ENDLESS AMOUNTS OF MONEYS!!... THIS MEANS GRABBING A DA$MN WRENCH AND LEARNING TO WORK ON IT YOURSELF .. OR GO BACK TO BEING A COMAPNY DRIVER FOR SOMEONE ELSE.. BECAUSE YOU WILL TAKE HOME MORE MONEYS IN THE END!.

OWNING A TRUCK === LEARNING TO OWN IT.. AND WORK ON IT.. AND REPAIRING IT.. AND DOING ALL THE THINGS THAT ARE NECESSARY TO KEEP THAT EQUIPMENT HEALTHY .. AND NOT .. TAKING IT ENDLESSLY TO.. >>>THEY! ... SO THAT "THEY" CAN EMPTY YOUR WALLET AND TAKE ALL YOUR PROFITS AWAY EVERY COUPLE YEARS!

==== THAT IS THE SYSTEM .. AND YOU ARE WHOLE HEATEDLY SUCKED RIGHT INTO IT LIKE THE GOOD LITTLE TRUCK OWNERS THAT YOU ARE, WITH ALL THE GLEE AND FANCY LOGO-BASED BUILDINGS AND FANCY OFFICES AND FANCY WAITING ROOMS WITH TELEVISIONS SETS .. ALL SUCKING YOU IN LIKE FOOLS TO TAKE YOUR MONEYS ENDLESSLY WHILE THEY THROW EX$$$ PARTS AT YOUR TRUCK, KEEPING YOU DOWN VIA THEIR WELL-KNOWN INCOMPETENCE, JUST LIKE I MENTIONED ABOVE!!!!.

STOP.. STOP..STOP.. TAKING IT TO... AND LISTENING TO ... "THEY"!!! .. AND GRAB A GODDAMN WRENCH!!!.. AND START TAKING THINGS APART!... FIX YOUR ISSUES.. AND STOP WASTING DAMN MONEYS !!!

HAVE YOU EVEN BOTHERED TO TAKE THE INTAKE ALL APART AND DO A THOROUGH EGR-TUNE-UP ON IT?

WHAT HAVE YOU DONE FOR YOURSELVES ... BESIDES RUN OFF OVER AND OVER TO ... "THEY!" ?????

HAVE YOU Invested in AN ADAPTER AND INSITE SOFTWARE FOR A FEW HUNDRED BUCKS, and a laptop to work on the engine with?...

WHAT HAVE YOU DONE?... BECAUSE "THEY" are not going to fix issues like this... they are not trained to!.


-=== do you see my point yet? ... -== I am trying to make it as clear as possible.. yet again... THAT YOU!.. THE TRUCK OWNER!.. IS THE ONLY ONE AT THE END OF THEY DAY who has to work on issues like this for yourselves, because "they" are not trained to take all the intake apart and clean it out.

doing THOSE THINGS (egr tune-up, cac and other minor to medium maintenance, work, checks, etc.) that keep problems like you describe at bay to begin with. It is just like all the doctors telling you to eat as much damn sugar, starch, potatoes, and noodles as you want to.. so that later on they can sell you (or your insurance company) that expensive heart surgery when your heart clogs up!.

====

back on the actual issue that you described ...

The issue with it not getting to temp and cancelling is likely a safety issue. if thas ecm detect the fuel is not burning.. it will cancel instead of letting it pool up in the DPF unit where it could potentially burn the truck to the ground. It is likely doing its job correctly. -= What you have to do is find out why it is not staying at operating temp during a regen cycle.

START BY DOING A THOROUGH EGR SYSTEM TUNE-UP ON IT!!>.. AND REPLACE THE IMAP + OTHER OLD EGR AND INTAKE SENSORS!!>.
here is some more info on this...
ref: http://rawze.com/forums/showthread.php?tid=7&pid=9#pid9

Things like taking apart all of the EGR piping and clean it all out. Repling the Doser injector + doing engine and exhaust system pressure/leak tests.. Checking the intake and CAC for leaks... etc.etc.etc.etc... <-- all the things that "they" are not going to do because they could not be bothered with it!>

START by verifying 100% that there are no intake, CAC, or exhaust leaks at all. CLEAN OUT that circuit thru the thermostat housing for the exhaust back-pressure sensor...

And if you think the Ambient temp sensor is bad.. then unplug it and see what faults you get.. replace it and see if it starts working.. etc.
