My truck coded the other day...P2201. Turns out I need a new SCR and DEF injector nozzle as well as dropping the DEF tank to empty it. I wondered why the DEF gauge kept showing 100% so long. All this I suspect is the result of the truck not being driven for weeks in hot weather and compromising the DEF. Medical issues kept me grounded and now my truck is sick.

It seems the new emissions work great if your truck is on the road a lot, but not so much if it sits around. From now on I will keep a small amount of DEF in the tank.

 

They don't work great, I'm fighting an intermittent def issue with my 14. I'm about to start calling these scr trucks junk. Maybe it is just mine.

 

Keeps me very busy, I have never been this backed up with work since 2007 when the 6.7 first came out. Now I have 3.0 Eco diesels issues on top of the 6.7 SCR issues. Life is good.

 

That's very disheartening. I thought the newer DEF trucks were the way to go, and they had them reliable now.

 

my 2013 has a message that says DEF system needs service. Can we do that ourselves? My 2013 has 71K miles.

 

Have you guys had the recall done yet? No problems since I had mine done.

My 2014 goes in this morning for 2 recalls, the catalytic converter and the re-flash of my occupant restraint module.

 

My '14 has 83K and I'm just about ready to pull the trigger and get it deleted. I'm on my third catalytic converter. Every problem I've encountered with this truck is with the DEF system. Absolutely 0 other problems.

 

While my 11 is def free, I do own other rigs and big rigs that take it and let me tell you- they all start having issues after 100k or so, bad heaters, corroded level sensors, corroded nozzles & pumps are pretty common
Even farm machinery has this crap now

 

I have a friend with a 2014. He deleted at 10,000 miles after several trips to the dealership due to the sensors on the exhaust system. He never has been back to see them since and he has 150,000 miles on it.
His only regret was not doing it sooner.

I believe my only regret will be the same as your friends.

I'm calling tomorrow to schedule an appointment with a reputable company to delete her. Could I do it myself? Yes. Will I do it myself? No.

Too many variables for me to attempt. Delete the EGR, add 5" exhaust and fool the ECM. No tuner, just a fooler. Personally I don't need a tuner. I don't race, I don't off road. I pull my camper and other equipment. That's it.

 

I totally agree with your thoughts. With the kind of power these trucks are putting out, it's hard to justify adding any more when the possibility of destroying the driveline is so likely.

 

True. At least in my case.
