OP here. Other than at idle the engine is completely silent in the cab when driving, we have never detected a regen event. There is only a drive position on the selector, you can downshift with the paddles but it reverts back to a lower gear in short order.
The liqui-Moly is not a fuel additive but a DPF treatment that includes spraying a solvent and rinse through the DPF sensor hole then starting the engine and shooting the dissolved soot in solution out the tailpipe. I was hoping someone had tried the process.
I see on some websites that DPF clogging is even prevalent on the big rigs and equipment has been developed to clean them but requires removal.
I'll try regular longer trips at higher speeds and see how it goes. We really love the vehicle and would hate to give it up.
Yes stay away from the fuel additive type DPF cleaners. We've had some success with some of our John Deere equipment that received a sprayed in DPF cleaner, with good results and some required the DPF to be replaced. For your situation I believe you need to get the vehicle on the highway more often with some complete regens and all maybe good again.
