Regen issues, jackhammering.
I am looking at a used 2015 6.7 with 36,xxx miles. My question is does anybody know what percentage of the production run is affected by this condition? The truck has a Carfax that shows a program #17mo4, crankcase ventilation oil separator assembly. I know those are two different things, my point being wouldn't the Carfax also show the regen issues had the truck been taken to a dealer for service?

I guess my question should have been are there good ones and bad ones in regards to the 2015 model year as far as jackhammering is concerned. I have 2011 and a 2012 with the only issues being egts's and a reduct heater, all of which Ford fixed free of charge. It is my understand that Ford has increased the warranty on these items to 10 years,100,000 miles. Please correct me if I am wrong.

OP what is your concern with that issue?
Mine had it and I got it fixed, no problems since other than a DEF level error because a dealer topped off the fluid and confused the system.
Others have had the same issue and had it corrected, and reading these forums I have not seen any problems crop up once these trucks were repaired and/or updated. In fact the issue came and went pretty quick and is rarely discussed anymore.
You can't tell which trucks had it and which ones didn't unless you pull Oasis to see if it had the repair or at the very least had the calibration updated.
Engine warranty hasn't changed on these trucks.

The trucks for the most part were 2011-2015. TSB 15-0088 covered the 2011-2015's. Check the TSB 16-0041 to see it this might cover your condition.

But the problem was far more prominent in the 15-early 16 models than it was in the 11-14's. It's a shudder that only happens during regen, and typically early in the regen. Easiest fix is a calibration update that will solve most issues. A more intrusive fix if the problem has been going on for a while is to replace the exhaust valves on the driver's side head along with the calibration update.

Dealers get new TSB's..... DAILY.
There are thousands and thousands of them posted across all model lines. This particular issue was one that came and went quickly. Mainly because it was a very noticeable issue by the customer, and a very precise and rapid fix.
The issue died quickly and moved out of dealer's minds. Since then they've been bombarded with other TSB's, recalls, etc. Even more is not all dealers had customers come in for this issue. Some never once saw a single recall for this issue. So it's not surprising that some dealers have forgotten or never knew about it in the first place.
And please don't take this as a slam against Ford or questioning quality concerns, etc. This happens across all vehicle makes.

I’m not surprised they were deer in the headlights. I’m at the dealer now waiting for a ride out of here. They jotted down the TSB #s and will look into it. I believe the last TSB pertaining to the issue was listed in October of 2016.

Just got the call from the service manager. This guy knows his stuff for sure. He said he’s dealt with this on a lot of trucks and will not bother trying the PCM flash first because it’s a complete waste of time. Ford used this dealership, plus two others in the US as R&D hamsters to figure out the best permanent solution.
Pull head and upgrade to new design exhaust valves. Reinstall head and everything else. Use the Ford Motorcraft Cetane in your fuel. This dealership was able to eliminate the bucking with the old valve design just by using the Cetane. The Service Manager told me that he recommends it for the new design valves as well.
I asked about reprogramming to use both heads for regen and he said that’s not a viable option. He said all work on any diesel brought into their shop is done by their master tech. I met the master tech before and the guy is legit. The service manager told me when I call in to get my truck maintained and/or serviced, to speak with him directly moving forward. He said his writers are struggling and he doesn’t want me to deal with them anymore.
