So with a 2016 Platinum, any idea if that option can be added? My truck has the problem oif regening to often. I am currently averaging about 140 miles between regens and I can see on my CTS2 that I will be regening on my way home form work before the filter will be full. I just regened Friday, drove the truck a bit to the store over the weekend and alerady need to regen.

Tom,
I'm sure smarter guys will give a more detailed response. The manual re-gen is a stationary process, and only really necessary if you use a PTO accessory with your truck. In my experience, re-gens are really a non-issue if you drive your truck for more than to the grocery store and back. The engine needs to get up to temp, and get out on the highway. The DPF% gauge will countdown during a regen. Soot burning while not in re-gen is referred to as a "passive re-gen", and occurs at temps above 700 or so. That is easily achieved while towing a heavy trailer, but otherwise not. Even if getting passive regeneration, the truck will still do a commanded regen about every 500 miles regardless of DPF%.
I've owned a 2011 6.7L, and now the 2016, and have never had an issue with the re-gen process.
Other items to be picky on:
- only put diesel fuel in fuel tank. I personally don't let anyone else fuel the truck. Gasoline, or DEF in the fuel tank can be an extremely costly mistake
- When adding DEF, do NOT be distracted. Guys get busy talking on phone, etc, and have poured it into the fuel tank instead of the DEF tank. IF this occurs to you, do NOT turn the key at all, in fact some will pull the fuse to the frame mounted fuel pump so that it wont get pumped up through the fuel system.
Both of these items can be a $10K or more problem.
Other than that, just drive it!
