Ram Truck Emissions Recall N40 (Cummins Diesel)
I had my truck in the dealership the other day for routine maintenance (because it was handy), and they told me there was a recall to reprogram the powertrain control module, and asked if I had time to get it done also.
I asked them what it was for, and they said it was for "emissions". I asked if it would hurt my fuel mileage, and the rep said, "Oh no, if anything it will help you fuel mileage". This guy must be taking lessons from some of the politicians of today.
Bottom line, my fuel mileage has gone down a solid 15%, both towing and running empty since the change. So, if you have a Ram 2500 with the 6.7L Cummins engine built before '13, you will probably be getting the recall, and if I had it to do over, I would not let them change it.
