Ticking from DPF/Muffler area during regen

Is there anyway to know our trucks are in regen mode? A buddy of mine has the GMC Canyon diesel and his pops up on the screen informing him it started regen mode. I have about 1,200 miles on my truck now, and as far as I can tell it has entered regen mode at least 2 times as I am just under 3/4 full on DEF tank now, and I have that gauge displayed to keep an eye on it.
I enabled the DPF % Full view with Forscan.
I can tell when it goes into Regen, when it gets to 100% it immediately goes into Regen. Mine can regen in 20 mins or so of driving.

·Your hear ticking from the heated metal. The regen (if like the 6.7) runs the EGT to almost 1300 degrees. The ticking I've heard (6.7) is usually as the pipes, etc. cool back down.
I haven't heard any ticking from the 3.0 yet. I've had to put a jug of DEF in mine already. It gave me the 500 mile warning at 2,650 miles. I"m at 3770 miles, the oil life is showing 57% remaining life.
The 6.7 always showed a message when doing the regen, I haven't seen one on the 3.0
I had Edge gauges on the 6.7 so I could see the EGT's and make sure I didn't shut the engine off while it was still at high temps. I need to find some gauges for this one so I can see it on this one.

I can hear it in my truck too, when I first heard the ticking I had my windows down and went to take off and I heard it got the truck back home at and got out and looked around it was coming from the DPF / muffler and when u press the gas the tick got faster ?

I've only heard the ticking a few times after parking in the garage when returning home. From this thread, it does sound like metal under the truck cooling that was heated up for an in-progress DPF regen. This is why I will be adding the DPF % with FORScan so that I can know if I have reached 100% and DPF regen is in progress or not.

How soon do you think you will do the delete? Are you going to do it during the warranty period? Just curious.
Yes I will. Ive done 2 6.7s that way and they were in the shop less (not at all) compared to buddies stock 6.7s (all in shop for emissions issues only).
Ill maybe do it around 10k once I feel comfortable with motor, maybe sooner. I will not turn up power, just run delete. Or if I turn up power, just first level.
If anything happens I will put back to stock, or just eat cost and fix myself. I am pretty good when it comes to these fords and know alot of people to fix them, although I dont think it will ever get to that if you dont go crazy on turning up power levels.

What were the FORScan changes to make this appear? I have been searching online to figure this one out, and since you did it, thought to ask.
Thanks
I believe I followed this from the F250 forum.
Add DPF Filter % to screen IPC 720-07-02 x7xx xxxx xFxx xxxx This adds the DPF % screen to the Truck Information screen. Some trucks will report a camera error after making this modification. To avoid that, make your update according to the following: If your original default value is 0, change to 8; if 1, change to 9; if 2 then A; if 3 then B; if 4 then C; if 5 then D; if 6 then E, if 7 then F (as shown)

That is the correct code. The superduty is the same as the 150.

I came home last night and parked in the garage and heard the ticking sound again that I had interrupted yet another DPF regen cycle. I would say this has happened to me now probably 4 times, maybe 5.
So, I said enough is enough, and I can confirm that what is posted above is the correct coding for bringing DPF % Full to the instrument panel cluster (IPC), the same as for the Super Duty. Once I got it to display, it showed 80% full. So, that tells me that I was in a regen when I pulled into my garage, and that my countdown from 100% Full to 0% Full had only made it 1/5th of the way down. Next time driving the truck the regen does not resume, but it starts filling back up from 80% to 100% to trigger another regen.
I have about a 15 minute drive to work. My theory is that I reached 100% several times while not far from home and pulled into the garage with a regen partially complete. Then, it doesn't take that long for this cycle to repeat itself.
With the mod to the IPC and ability to see DPF % Full on my display, this morning I drove it to 100%, and then watched as the 100% started dropping in 5% increments (same as it goes up in 5% increments) as I drove some highway miles at 60-70mph. It took about 18 miles of driving for it to go from 100% Full down to 0% Full.
Now that I can keep an eye on the % Full, I can try to plan a little better so that I am on longer highway runs when I approach the 100% Full reading. This will keep me from being in what seemed like a frequent regen situation, and often times interrupting it when I parked in my garage. I should say that if I wasn't watching the DPF % Full gauge I would have had no idea I was undergoing a regen down the highway this morning--no abnormal noises or any indications other than my fuel mpg were looking about 18mpg during the regen.
Thought to share this in case it is insightful for anyone else. I am coming from a 2010 F150 5.4 Triton, and this is my first ever diesel, so I am going through the learning curve right now to figure all this out.
Merry Christmas and Happy Holidays to all!
