2019 Ram 3500 purchased new December 2019 it has run flawlessly for 46,000 plus miles pulling my 40' fifth wheel. Not once has the "Regeneration in Progress" come on.
Fast forward to last month when I took it in for the HPFP (high pressure fuel pump) Recall. After installing the previous generation Bosch CP-3 fuel pump the "Exhaust system regeneration in progress continue driving" message has shown up 3 different times.
My thoughts are the truck does not operate as it should with a fuel pump that was not designed or engineered for this particular engine.... it was designed for the Bosch CP-4 fuel pump. I too have notice a downgrade in fuel mileage!
Any thoughts apperciated.
