Got it from Harbor Freight, about $100 - ordinary reader
If you're wondering about the "permanent code" - once you've fixed the issue and cleared the active code, drive it normally for a day or two and the ECU will clear the "permanent" one. It has to sense that the code setting condition no...
When I get the DEF code (DEF pressure too high, or similar) I take the nozzle out of the exhaust, steam clean it and the hole it was in, with a little, cheap unit I bought off Amazon for $30-$40. Comforday, I think is the brand. After that's done I reset the code and all is well for another...
I, too, have a 2015, currently at 156k mi - had since 26k mi. Here's what I do:
I've used a lot of Rotella T-6 full synthetic 5w-40, also Valvoline Premium full synth 5w40. I use 8qts oil w/ 2qts Lucas synthetic oil stabilizer. Changes at 8000 miles. Been thinking about going to 6k or 7k mi...
I'd also check that front injector installation for proper sealing with the head - sounded to me like an exhaust/combustion leak, the oilyness seems to originate around the injector, and there was smoke being pumped out immediately after starting as opposed to having to warm up a min before...
The main tuners like GDE and SFT have tuner units that have the new tune on it, you plug it into the OBD2 port and flash the ECU yourself. No need to send off the ECU.
Only other thing I can think of is to check continuity of wires and a visual for rub thru on the harness outer wrap. I know, a huge hemorrhoid, but I've seen others on various forums have issues with this.
Start off reading this link on the P200 and P2d2 codes. Yes, the last letters are slightly different than yours, but it will get you on the right track.

Like Mar said, replace the coolant valve; it's...
The relay is in the underhood fuse block. Should be inexpensive at a parts store and take seconds to change. Those seem to be notorious for failing. Seems like that would cause the symptoms you described.
I believe "reductant" is the DEF fluid and your pump isn't functioning properly. Check your DEF spray nozzle, it could be clogged with urea deposits, causing the issue.
When I had issues with my DEF system (don't recall the code), I cleaned the nozzle and mount hole with steam*, cleared the...
If you have trouble with getting SFT to turn off your EGR, you could use a restrictor in the tube to significantly limit the flow. There are some plates on the internet, but I've been using a very inexpensive MacGuyver restrictor (SFT stage 1 w/ EGR on - have to pass emissions still): 1 Ace...
Given that the regens had a positive effect, I'm thinking that your DPF just needs more time with EGTs above about 750°F to burn more soot off. If you have mountains nearby to do a long, highway speed, drive up, or access to a big, aerodynamically impaired trailer to pull down the highway...
If I may add...
That failed on my truck this last fall at about 150k mi. The independent shop that did it initially quoted $2600 to replace the rubber part and the forward (easier) metal tube. I opted for a complete, one piece assembly with braiding over the rubber tube. That added another...
After reading thru the W58 recall that John Jensen posted, it looks like if your truck DID NOT get the "Approved Emissions Modification" and the settlement money, they will replace your tone wheel and flash your ECU to read the cam sensor when the tone wheel fails. If your truck DID get the...
