Top the tank off this weekend and hit the highway... set the cruise at the speed limit and burn a tank without stopping... fill up and repeat on way home...
These trucks just ain't made to idle and run short distances like the old diesels were. You got to get them up to temperature and keep them there for a while or they get constipated.

Well I am mostly town and some highway. When I do go highway it's for a long haul. This truck should be fine. I can't imagine buying a 60 thousand dollar truck that drive around in town. That's fords problem

Be prepared to buy a lot of ex-lax for the truck if you gonna be a townie cause all the EPA crap is gonna keep it stopped up. It don't really matter how much it cost, fact is fact.

Ford said the customer "me" isnt going to like this but I am going to have to pay for having the EGR taken out and blown out to make sure there is no carbon and I will always have to run their additive.
Ford states that it is in their manual that I always have to run it. I am going to go get stuck with a 600 dollar bill for all this.

The Fuel additive is not going to do anything to prevent carbon build up. Have them show proof that it will and is required by Ford (actually Ford only recommends the additive.
Diesel fuel quality is critical for reliable engine operation. Motorcraft® Cetane Booster & Performance Improver, PM-22-A (U.S.) / PM-22-B
(Canada) can be added to improve fuel economy, starting ability, and reduce engine wear.
These trucks are not like trucks years ago. You do not have to go out and beat on it once a week to keep things "clean". Now that doesn't mean you can let it idle 40 hours a week, but normal driving is all it needs. If your EGR system is building up carbon and causing a problem, the root cause needs to be found.

That's okay... I agree you ain't got to dog these trucks every week to keep them clean...
But I'll bet you that if you are a townie and drive around in 6th all the time at speeds below 30mph, stopping and idling at lights for 5 minutes at a time you'll soon find that you're in the same boat as the OP with a constipated engine... These motors want to be driven so that they get to full temp and at a high enough rpm for long enough that they can burn off the soot. If you don't do that you'll need that ex-lax before long.
One way to prevent the problem is to drive them on the open road occasionally for a long enough period that they can do what they're designed to do.

Guys let's be honest....would u of bought a truck if the dealer told u it cannot do town driving. Must do highway and the truck is not designed to do city driving? I don't think so.

I recall the 5.4 4V - if you didn't hammer on the engine in the first 3k miles, the rings wouldn't seat properly and the engine would use oil for the rest of the life of the vehicle. A lot of engines have their own peculiarities.

If I were a townie and rarely drove the open road I would definitely NOT buy a new diesel truck. Now If I needed a diesel truck for my job and that job required that I drive for the most part under 40 mph and idle for an extended time frequently I would buy the truck and make every effort to drive it on the highway as much as possible. If that was impossible I would accept that I am going to spend a bunch of money periodically to fix the truck.

well i do get on the highway once a month. My town is not like NY either. It has 45 mph zones and stuff. Sometimes I am all highway then sometimes I am town. Just depends.
A gas engine cant haul what I haul. Either way lets see all the diesel truck people say you cannot use your truck in town and we will see how that goes.
So far DEF fault has not come back on and I am going to keep an eye on it. I think my issue has nothing to do with carbon build up at all but I could be wrong.

I had a NOX sensor issue @ 6200 miles and again @13k miles. Been running additive every tank and still had an EGR issue @ around 60k miles. I drive a lot of hyway. As I recall the issue was egr cooler as it was leaking. I have 2 6.7's and I run additive every tank. I figure it cant hurt.

I was tricked obviously
Had to delete mine to make it run but now I have no issues. I can let it idle ALL DAY LONG and in the winter some days I do.
